• Insert the plus and minus sides of the batteries properly according to the marks in the battery case.  
• Batteries with the same shape may have different voltages. Do not use different batteries together.  
Operating other PIONEER  
com ponents  
Operating range of rem ote  
control unit  
Connecting an optional control cord allows you to  
operate other PIONEER components simply by  
pointing the receiver’s remote control at the remote  
sensor on the front panel of the receiver. The  
receiver then sends the remote control signals to the  
other devices via the CONTROL OUT terminal.  
The area in which you can use the remote control to  
operate the VSX-D938TX/D908TX/D908TX-G is fairly  
large. To use, point the remote control toward the  
remote sensor on the front panel of this unit while  
within the range shown below.  
Remote control may not function properly if:  
• There are obstacles between the remote  
control and the remote sensor.  
• Direct sunlight or fluorescent light is  
shining onto the remote sensor.  
• The receiver located near a device  
emitting infrared rays.  
You can also control PIONEER  
components (and those made by other  
manufactures) by pointing the receiver’s  
remote control directly at the respective  
component. This type of operation does  
not require control cords. All you have to  
do is recall the appropriate preset code  
(see P.79 (VSX-D938TX), P.83 (VSX-  
D908TX/D908TX-G)).  
• Operated simultaneously with another  
remote control which uses infrared rays.  
• If you use a remote control hooked up via  
the CONTROL IN jack with a control cord,  
you will not be able to use this units  
remote control.

Connecting Your Equipm ent  
Audio Com ponents  
To begin set up, connect your audio components to the jacks as shown below. These are all analog connections  
and your analog audio components (turntable, cassette deck) use these jacks. Remember that for components  
you want to record with you need to hook up four plugs (a set of stereo ins and a set of stereo outs), but for  
components that only play (like a turntable) you only need to hook up one set of stereo plugs (two plugs). To use  
DTS surround sound features you must hook up your digital components to the digital inputs but it is also a good  
idea to hook up your digital components to analog audio jacks. If you want to record to/from digital components  
(like an MD) to/from analog components, you must hook up your digital equipment with these analog  
connections. See p.10-11 for more on digital connections.  
When connecting your equipment, always make sure the power is turned off and the power cord is  
disconnected from the wall outlet.  
NOTE  
• Only the VSX-D938TX has a 2 RF IN jack.  
• The arrow s indicate the direction of the audio signal.

Connecting Your Equipm ent  
Video Com ponents  
Connect your video components to the jacks as shown below. Regarding digital video components (like a DVD),  
you must use the analog connections pictured on this page for the video signal but in order to use Dolby Digital  
you should hook up their audio to a digital input (see the next page). It is also a good idea to hook up your digital  
components with analog audio connections as well (see the previous page). To cover all possible laser discs a  
DVD/LD player or LD player requires an analog connection (as shown here) and two digital connections (see the  
next page).  
When connecting your equipment always make sure the power is turned off and the power cord is  
disconnected from the wall outlet.

If your video components have S-video  
jacks, you could use S-video cords (not  
supplied) to connect them on the back of  
the receiver. These jacks are labeled by the  
Japanese designation “S2” on the VSX-  
D938TX/D908TX/D908TX-G but they are  
simply S-video jacks.  
Use audio/video cords (not supplied) to connect  
the video components and a video cord to

However, if you use S-video cords for your  
video hook ups you must also hook up your  
TV with S-video connections. Conversely, if  
you use regular composite video cords for  
video hook ups, you should use them for  
your TV as well.

Connecting Your Equipm ent  
Digital Connections  
In order to use Dolby Digital/DTS soundtracks and MPEG audio, you need to make digital audio connections. You  
can do this by either coaxial or optical connections (you do not need to do both). The quality of these two types  
of connections is the same but since some digital components only have one type of digital terminal, it is a  
matter of matching like with like (for example, the coaxial out from the component to coaxial in on the receiver).  
The VSX-D938TX/D908TX/D908TX-G has two coaxial and two optical inputs for a total of four digital inputs. For  
the VSX-D938TX, a DVD/LD player or LD player should be connected to a digital jack and the special AC-3 RF  
jack (if the LD has one) as well as a pair of analog jacks (see the previous page). Connect your digital  
components as shown below. There is one digital out jack which is marked PCM/2/DTS/MPEG(VSX-D938TX  
only) OUT. If you connect this to the optical input on a digital recorder (currently these include MD, DAT and CD-  
R) you can make direct digital recordings with this unit.  
When connecting your equipment, always make sure the power is turned off and the power cord is  
disconnected from the wall outlet.

Connecting Your Equipm ent  
Speakers  
A full complement of six speakers is shown here but, naturally, everyones home set up will vary. Simply  
connect the speakers you have in the manner described below. The VSX-D938TX/D908TX/D908TX-G will work  
with just two stereo speakers (called “front” speakers in the diagram) but the receiver is designed to be used  
with at least three speakers.  
Make sure you connect the speaker on the right to the right terminal and the speaker on the left to the left  
terminal. Also make sure the positive and negative (+/–) terminals on the receiver match those on the speakers.  
When connecting your equipment, always make sure the power is turned off and the power cord is  
disconnected from the wall outlet.  
The VSX-D938TX/D908TX/D908TX-G has two speaker systems, A & B. A is the main system supporting  
the full complement of surround sound speakers. If you switch on both A & B speaker systems, only  
front speakers and the sub-woofer will be audible. No sound will come from the center or surround  
speakers but multi channel sources will be down-mixed to the active speakers so no sound will be lost.  
Similarly, if you choose just the B system, you will only hear the front speakers connected to the B  
system and multi channel sources will be down-mixed to these two speakers.

Speaker placem ent  
If you have a multiple speaker arrangement the placement of the speakers is extremely important. To achieve  
the best possible surround sound, install your speakers as shown below. Make sure all speakers are installed  
securely to prevent accidents and improve sound quality. Be sure to consult your speaker manuals for the best  
placement of the speakers. Some speakers are designed to be floor-standing but others benefit greatly from  
speakers stands which raise them off the floor.

• Install the left and right front speakers at equal distances from the TV.  
• When installing speakers near the TV, we recommend using magnetically shielded speakers to  
prevent possible interference such as distortion in the color of the TV screen. If you do not have  
magnetically shielded speakers and notice discoloration of the TV screen, place the speakers farther  
away from the TV.  
• Install the center speaker above or below the TV so that the sound of the center channel is localized  
at the TV screen.  
CAUTION:  
When installing the center speaker on top of the TV, be sure to secure it with tape or some other  
suitable means. Otherwise, the speaker may fall from the TV due to external shocks such as  
earthquakes, and it may lead to endangering those nearby or damaging the speaker.  
• If possible, install the surround speakers slightly above ear level.  
• It may be difficult to obtain a cohesive surround effect if the surround speakers are installed farther  
away from the listening position than the front and center speakers.

Connecting Additional Am plifiers  
Although the VSX-D938TX/D908TX/D908TX-G has more than sufficient power for any home use, it is possible to  
add additional amplifiers to your system. If you want to use separate amplifiers to power your speakers, make  
the connections shown below.  
When connecting your equipment always make sure the power is turned off and the power cord is  
disconnected from the wall outlet for all the eqiuipment.

Surround Sound Set Up  
On Screen Display  
There are a number of possible ways to hook up the receiver to your video components like a DVD player and  
hook up to your receiver to your TV, but some of them will not allow you to use the on-screen display of this  
unit. To avoid this one simply needs to follow two rules.  
1 Always use the same type of video cords to hook up your video components to the receiver as you use to  
hook up the receiver and your TV. For example, if you use composite video cords to hook up your DVD and  
the receiver, use composite video cords to hook up the receiver to your TV. If you use S video cords to hook  
up your DVD and the receiver, use S video cords to hook up the receiver to your TV.  
2 Always make sure your TV is set to the appropriate input channel on your TV (for example, video 1). Your TV  
may have a number of input channels and if you do not select the proper one you will not be able to use this  
receiver’s on-screen display. If you are unsure how to choose an input channel for your TV, refer to the  
manual which came with your TV.  
You might, for example, use both composite and S video cords to hook up your video component with this  
receiver and then use composite video cords to hook up this receiver to your TV. This arrangement would still  
NOT let you see the on screen displays from this receiver on your TV. The best idea is just to use one type of  
video cord for all your video component and TV hook ups.  
Sw itching video system betw een PAL and NTSC  
This receiver is able to use two types of video systems for its OSD (on screen display) and you need to set the  
receiver to the type of video system you have, either PAL or NTSC. If you do not match the system on the  
receiver with your home system no OSD will appear on your TV. People with multi-system TVs, dont need to  
worry about changing the setting. If necessary, follow the instructions below to switch the type of video  
system.

Surround Sound Set Up  
Setting Up for Surround Sound  
To ensure the best possible surround sound, be sure to complete the following set up operations. This is  
particularly important when using the DTS, 2 (Dolby) Surround sound and MPEG (VSX-D938TX only) modes.  
You only need to make these settings once (unless you change the placement of your current speaker system  
or add new speakers, etc.). These set up operations use your TV to display the settings and choices so be sure  
your TV and receiver are properly hooked up.

If you have a sub woofer and like lots of bass, it may seem logical to select LARGE for your FRONT  
speakers and leave the sub woofer selected. This may not, however, yield the best bass results.  
Depending on the size and shape of your room, you may actually experience a decrease in the amount  
of bass due to what is called “low frequency cancellations.” If you have a sub woofer, listen to the bass  
response with the FRONT speakers set to LARGE and SMALL alternatively and let your ears judge  
which sounds best.  
The safest option in this case is to route all the bass sounds to the sub woofer by selecting SMALL for  
the FRONT speakers.

Channel delay  
Adding a slight delay to some speakers is necessary to achieve a surround sound effect. You need to figure out  
the distance from your listening position to your speakers to add the proper delay. The following steps show you  
how to set the delay time for each channel by specifying the distances from your listening position to each  
speaker. Once you specify the speaker distances, the receiver calculates the correct delay times automatically.  
If continuing from SPEAKER SETTING, go to step 1. If starting fresh, complete steps 1-3 in Setting Up for

D-range control  
This feature makes it possible to enjoy full surround sound effects on Dolby Digital sources even at low  
volumes. It does this by compressing the dynamic range. Dynamic range is the difference between the loudest  
and the softest sounds in any given signal. Compressing the range plays sounds so the quieter ones are audible  
and the louder ones dont get distorted or become overpowering. This feature only applies to Dolby Digital  
sources but the MIDNIGHT LISTENING mode accomplishes the same end for a variety of sources (see p.46). If  
continuing from BASS PEAK LEVEL MANAGER, go to step 1. If starting fresh, complete steps 1-3 in Setting

Sound Modes  
The six sound modes on the VSX-D938TX (The five sound modes on the VSX-D908TX/D908TX-G) are explained  
here. These can be turned on from the front panel or from the remote control.  
There are four (VSX-D938TX) or three (VSX-D908TX/D908TX-G) cinema modes: STANDARD, MPEG (VSX-  
D938TX only), HOME THX CINEMA, and ADVANCED THEATER. These are designed to be used with multi  
channel surround sound audio/visual sources (like DVDs and LDs). Intrinsic to home theater, these modes can  
deliver realistic and powerful surround sound that recreates the movie theater experience. You may need to  
experiment with them to see which settings suit your home system and personal tastes.  
The DSP and STEREO modes are designed to be used with music sources but some DSP modes are also suited  
for film soundtracks. Again, try different settings with various soundtracks to see which you like.  
You must choose one of the three cinema modes or the DSP mode in order to get surround sound. In STEREO  
mode, only the front two speakers are used.  
STANDARD m ode  
This mode is for pure decoding of Dolby Digital, DTS and Dolby Pro Logic. No special effects are added. It is  
good for enjoying movies that have been recorded in Dolby Digital, DTS or Surround.  
HOME THX CINEMA m ode  
THX is a set of technical standards created by Lucasfilm, Ltd. These standards were designed to emulate a film  
sound stage and thus reproduce, with the greatest possible accuracy, the soundtrack intended by the  
filmmakers.  
For more detailed information, see P.78.  
MPEG m ode (VSX-D938TX only)  
Use this mode to enjoy playback of software recorded in MPEG audio.  
ADVANCED THEATER m odes  
The Advanced Theater mode is a newly designed system for enhancing movie soundtracks and other audio-  
visual sources. It incorporates the use of DTS (Digital Theater System) as well as Dolby Digital into its sound  
processing. These functions switch on automatically when the source you are playing is encoded with DTS,  
Dolby Pro Logic or Dolby Digital (bearing the  
logo). There are four Advanced Theater settings that use  
1
DSP (Digital Signal Processing) to create different types of sound environments.  
MUSICAL  
This mode is primarily for music and adds a spacious feeling to the sound. A long delay time of reflected  
sounds, provides resonant tones which emulate a concert hall.  
DRAMA (CINEMA)  
This mode is designed for movies with a lot of dialog. The elements of dialog are enhanced, making the  
characters seem more real. The mode also compresses the dynamic range somewhat so loud sounds do not  
overpower softer ones (compare this with the MIDNIGHT LISTENING mode explained on p.46).  
ACTION  
This mode is designed for action movies, which generally use lots of sound effects. The mode enriches the  
sound to make it more realistic and extends the parameters to pick up high and low sound effects.  
5-D THEATER  
This mode is especially designed to give sound depth to stereo sources. The overall effect builds a dynamic  
and broad sound space, allowing two-channel (stereo) signals to faithfully imitate a five speaker sound. The  
mode should be used in conjunction with Dolby Pro Logic for sources bearing the 3 mark.  
When a Dolby Digital soundtrack is played back, the Dialog Normalization function of the receiver  
activates automatically. Dialog Normalization is a Dolby Digital function that establishes the average  
dialog level for the program source being played. If the receiver’s level does not match the average  
dialog level, first you see “DIAL. NORM” flash in the receiver’s display and next OFFSET + 4 dB (as an  
example) will appear. The number +4 dB is the difference between the receiver’s gain structure and the  
Dolby Digital average dialog level. To match the average dialog level, subtract or add the OFFSET level.  
Fleovreel.xample, if the OFFSET level is +4 dB, the amplifier’s output is 4 dB over the average recorded 39

DSP m odes  
The DSP (Digital Signal Processing) modes allow you to transform your living room into a variety of different  
sonic environments when playing either two-channel or multi-channel sources.  
HALL 1  
Simulates the acoustic effects of a large concert hall. Suitable for classical music.  
A long delay time of reflected sounds, coupled with reverb effects, let the listener enjoy the dynamic and  
rich sounds characteristic of concert halls and powerful orchestral performances.  
HALL 2  
Simulates the acoustic environment of a very resonant concert hall. Rich reverberation and a full sound  
create the impression of a lively performance space.  
J AZZ  
Simulates the acoustic effects of a jazz club. Reflected sound is virtually below 100 msec so that the listener  
can enjoy a live band effect.  
DANCE  
Simulates the acoustic effects of a dance club. Features a strong bass sound.  
Reflected sound delay time is virtually below 50 msec, for the listener to enjoy the the visceral power of  
dance music.  
THEATER 1  
Reproduces theater sound field effects without losing the localization of each channel. Theater effects can  
be enjoyed without losing Dolby Digital/ Pro Logic effects when used in combination those formats (with  
movies bearing the 3 trademark).  
THEATER 2  
Simulates the acoustic environment of a theater while maintaining proper localization of each channel.  
Stereo m ode  
Use the STEREO mode to enjoy standard (two-channel) stereo sound from the front left and right speakers.  
This m ode also allow s you to :  
• Use the BASS and TREBLE tone controls  
• Use DIRECT for truer reproduction of the original recording.  
• Use DIGITAL NR.  
See display explanations on p.18-19 and front panel explanations on p.20-23 for details on SPEAKERS (A/B),  
BASS (–/+) and TREBLE (–/+). See P.45 for DIGITAL NR explanation.  
When listening to Dolby Digital or DTS sources, DIGITAL NR do not function even if you select  
STEREO.

Selecting a Sound Mode  
To ensure the best possible surround sound, be sure to complete the set up procedures described in Setting  
Up for Surround Sound” (starting on page 27) before using the sound modes. This is particularly important when  
using the 2 (Dolby) Digital or DTS sources. When using the sound modes, using SPEAKERS A will give the  
best results. If you use SPEAKERS B, the sound will be down mixed to the two front B speakers and the  
surround sound effect will be lost.

We recommend using different modes for different types of  
DTS material. For watching movies, the THX or ADVANCED  
THEATER setting should provide the best results. For listening  
to music, the STANDARD, DIRECT, STEREO, or DSP modes  
should serve the listener best.

When playing LD recorded in Dolby Digital  
4
When connecting a DVD/LD or LD player using the AC-3 RF  
output, a commercially available RF demodulator (RFD-1) is  
required. The RF demodulator changes the RF signal to a digital  
signal which is then processed by the receiver at the digital  
input jacks. For more details, refer to the instruction manual  
supplied with the RFD-1 (see p.11).  
Refer to pages 76-78 for explanations of Dolby Digital, Dolby  
Pro Logic, DTS, and MPEG (VSX-D938TX only).  
VSX-D938TX m odel:  
Make sure you connect your DVD/LD or LD players using the  
AC-3 RF jack. If your player has an AC-3 RF output, this will  
ensure you can use all LD players. Refer to page 10, 11 and 37.

Using MPEG audio discs (VSX-D938TX only)  
The VSX-D938TX can decode a variety of different types of audio formats for DVDs and these include MPEG.  
MPEG is a highly sophisticated audio encoding system which some discs use. If the disc you are using has  
MPEG audio (it will be marked on the disc) switch the receiver to MPEG using the procedure below. If you try to  
play an MPEG audio disc in any mode other than MPEG no sound will be heard.

Sw itching ANALOG/ DIGITAL signal input  
This switch moves the input fed to the receiver between analog, digital and AC-3 RF sources. You need to take  
special care to switch to the appropriate input, when necessary. For example, the switch would have to be on  
digital to use DOLBY DIGITAL, DTS surround sound and MPEG audio (VSX-D938TX only) but it would have to be  
on analog to record from the analog out jacks on the receiver. On the VSX-D938TX, the default setting is AUTO  
(which chooses digital when all three are available but foes with whatever is available if it is the only choice), on  
the VSX-D908TX/D908TX-G is ANALOG.

formats. It cannot play back digital singals other than these so  
for those formats you will have to play them back in an analog  
manner (making sure your equipment is hooked up with  
analog connections and setting the SIGNAL SELECT to  
ANALOG.”  
• When an LD or CD with DTS is played back with the SIGNAL  
SELECT set in ANALOG,” digital noise caused by playing  
back the DTS directly (with no decoding) is output. To prevent  
noise, you need to make digital connections (See p. 10, 11)  
and set SIGNAL SELECT to DIGITAL(VSX-D938TX could  
also be set to “AUTO).

Listening in MIDNIGHT LISTENING m ode  
This feature makes it possible to get excellent surround sound effects even when listening at low volumes. It  
can be used with a variety of surround sound sources and plays soundtracks so that the quieter sounds are  
audible while the noisier sounds do not become overly loud or distorted. It does this by bringing all the sounds in  
a given soundtrack closer together in volume. Compare this feature with the D-Range Control (only for Dolby

(DSP modes. ADVANCED THEATER modes, DIRECT mode,  
TONE controls, etc.), as well as the TUNER and PHONO  
modes, cannot be used. Also, all speaker settings and other  
setup settings have no effect.  
96kHz/ 24bit perform ance  
This receicver is capable of playing back advanced DVD discs which are recorded in 96 kHz/24 bit format (these  
are all stereo discs). The receiver will automatically read the format of the disc and play accordingly (of course  
the SIGNAL SELECT will have to set to AUTO (VSX-D938TX only) or DIGITAL to read the DVD soundtrack).  
When the receiver plays a 96 kHz/24 bit disc “96kHz” appears in the display. If you try to use one of the  
functions or modes mentioned below “96kHz” will light on the display, as shown below, indicating the  
procedure is not possible.

Rem ote Control of Other Com ponents  
Setting Up the Rem ote Control to Control Other  
Com ponents  
In addition to controlling the receiver, the supplied remote control can operate your other components (VCR, TV,  
LD, CD, etc.) after you program it to do so. In this way, instead of fumbling with many different controls and  
buttons, you only need to use one remote control. If your component(s) are listed in the remote control’s  
memory, simply follow the steps below. If your component(s) are not listed, or if you want the remote control to  
learn additional operations, you can use the learning mode to input the information from the remote controls  
supplied with your other components.  
Recalling preset codes  
The following steps show you how to recall preset codes stored in the remote control. Once a preset code is  
recalled and the component assigned, you can use this remote control to easily operate the component.  
See “Preset Code List” on p.79-82 (VSX-D938TX), 83 (VSX-D908TX/D908TX-G) for the components and  
manufacturers available.

The following explanations show you how to record an analog audio signal with the component you connected  
to the MD/TAPE 1 or TAPE 2 MONITOR jacks. Note that you cannot record an component that is only  
connected digitally. If you want to record from a digital component, it must be connected in an analog manner as  
well. If you want to record a digital signal, see the next page.  
The receiver’s volume, channel level, tone (BASS, TREBLE, and LOUDNESS), and surround effects  
have no effect on the recorded signal and the EXTERNAL DECODER input cannot be recorded.

Using Other Functions  
Recording from Digital Audio Com ponents  
The following explanations show you how to record digital audio. Using this method you can make exact digital  
copies of sources like CDs or MDs. The only drawback is that you cannot switch between various recorders at  
the touch of a button like you can with analog recordings (see the previous page). If you look on the back of the  
VSX-D938TX/D908TX/D908TX-G, you will find a digital out jack which is marked PCM/2/DTS/MPEG (VSX-  
D938TX only) OUT (it is to the right of the digital in jacks in the upper left-hand corner). If you connect this to the  
optical input on a digital recorder (currently these include MD, DAT, CD-R, and DVD video recorder), you can  
make direct digital recordings with this unit. Of course, the digital components you want to record all need to be  
connected to the VSX-D938TX/D908TX/D908TX-G with digital inputs as well. See p.10 if you have not made  
these connections.  
The receiver’s volume, channel level, tone (BASS, TREBLE, and LOUDNESS), and surround effects  
have no effect on the recorded signal.

Recording from Video Com ponents  
The following operations show you how to record audio and video to the video tape recorder connected to the  
VCR 1 or VCR 2 jacks. Note that all signals coming out of these jacks will be analog and it is not possible to  
record DTS soundtracks.  
The receiver’s volume, channel level tone (BASS, TREBLE, and LOUDNESS), and surround effects have  
no effect on the recorded signal.

Using Other Functions  
Multi Operations  
Multi operations allow you to tell the receiver and your other components to do a number of things with the  
push of just two buttons on the remote control. For example, you can program the unit to turn on your TV, turn  
on your DVD player, go into a specific sound mode and start playing the loaded DVD. This feature allows you to  
decide which operations you want performed as well as the order in which you want them performed.  
The steps below show you how to program a string of up to 5 different operations based on eight possible  
components. You do not need to program the power of this unit, or any PIONEER product, to go on, it/they will  
do so automatically when the MULTI OPERATION function is used. Also, for some DVD players you will not  
need to program a play command. Most DVDs will start to play automatically if their power goes on and a DVD  
is loaded.  
Be sure to recall or teach the rem ote control com m ands for each com ponent before attem pting  
m ulti operations (see “Setting Up the Rem ote Control to Control Other Com ponents,” p. 54).

Using Other Functions  
Setting Up the Direct Function  
The direct function is designed in case you have an external video source connected to your TV (a video source  
that is not going through the VSX-D938TX/D908TX/D908TX-G). For this explanation we will call this the “external  
video deck.” You would like to control external video deck with this units remote control so you have assigned  
it a function button (for example purposes, the VCR 2 button). Yet, if you put the receiver in VCR 2 mode you  
will get no picture on your TV because the external video deck signal is not going through the VSX-D938TX/  
D908TX/D908TX-G. To get around this problem, you set the DIRECT FUNCTION for VCR 2 to OFF. Now when  
you press VCR 2 function button you can control the external video deck with the remote control but the  
receiver does not go into VCR 2 mode.

Dolby Digital  
Dolby Digital is a compression format which records  
the sound of 6 channels of the theater surround  
system (Dolby Digital) on the movie film digital track.  
Of the 6 channels, the sub woofer channel is  
intended for bass only, and because the frequency  
range is smaller than the main channel, it is  
expressed as 5.1 channel.  
Laser disc form at  
Laser discs are now available on the market in large  
numbers. This means that the recording of different  
format audio signals on the laser disc raises the  
important question of compatibility with existing  
laser discs. Dolby Digital tracks on Laser discs record  
signals using the space of one analog audio channel  
so it will maintain compatibility with existing discs  
and players.  
As shown in the following figure, the digital audio  
sounds of Dolby Digital discs can be played back as  
currently done. Analog sounds are played back by  
using the other channel without the Dolby Digital  
signals for monaural audio signals.  
Dolby Digital is the name of the Dolby surround  
multi-channel digital system that was developed  
after the Dolby Surround System and Dolby Pro  
Logic Surround System.

Com parison w ith Dolby Pro Logic  
Surround  
Dolby Digital for m ovie film s  
Dolby Digital is also known as the 5.1 channel  
system. It is equipped with 5 channels (front left,  
front right, center, surround left, surround right) in  
the frequency range from 20 Hz to 20 kHz and an  
independent Low Frequency Effect (LFE) channel.  
The sub woofer channel is also called Low  
Frequency Effect (LFE).  
The sub woofer channel can be used as desired to  
enjoy strong bass sounds.  
The table on the next page shows the comparison  
with Dolby Pro Logic Surround effects.  
The number of movies made using Dolby Digital  
since 1992 has exceeded 300 and continues to  
increase. For compact disc players and laser disc  
digital sounds, 16 bits are used to sample the original  
analog audio waveform and sampling is carried out  
44,100 times every second. However, because an  
enormous amount of recording signal data is  
required for the multi channel system with this  
method, AC-3 is used to compress the data.  
In reproducing audio signals, the smaller the bit  
number used, the lower the sound quality. With AC-  
3, drop in auditory sound quality is prevented by  
using masking technology and digital filtering  
technology based on the human auditory  
characteristics.

DTS  
DTS has been adopted as a sound recording format in the latest movie theaters since the release of “JURASSIC  
PARK” in 1993, and has a good reputation for high quality sound and dynamic surround effects.  
In this system, 6 channels of digital sound are recorded on CD-ROM, rather than on the film. DTS adopts a  
simultaneous playback format. With a low rate of compression of sound signals and a high rate of transmittance,  
a higher sound quality format is produced. Also, unlike the process of recording digital sounds on film directly,  
the only components required are a CD-ROM player as might be used with a personal computer and a DTS  
processor, and therefore less investment is required than with other formats. For this reason, the format is  
being introduced in more and more movie theaters, and is being adopted in home movie software (DVD, LD)  
and music software (5.1 channel CD).  
More than 11,000 movie theaters around the world have adopted the DTS format, which is now the most  
popular digital format for movie theaters, especially in U.S.A, Europe, and Asia.

Warning about DTS test m ode  
The VSX-D938TX/D908TX/D908TX-G has a mode for PIONEER repairmen to test the DTS sound quality. You will  
never need to access this mode. Rather you should be careful NOT to put the receiver in this mode because  
doing so will erase all your setup parameters like speaker settings, delay settings, channel settings, etc.  
STANDBY/ON  
In STANDBY m ode, holding the DIRECT button and  
pressing the STANDBY/ ON button w ill put the receiver in  
DTS test m ode. Be careful NOT to do this.  
DIRECT  
VSX-D938TX  
The above described method is similar to choosing either PAL or NTSC  
video setting and choosing 8 or 6 setting so be particularly careful  
when performing these operations noy to accidentally put the receiver in  
DTS test mode.  
If you accidentally put the receiver in DTS test mode, repeat the  
same procedure (as above) to put the receiver back in a usable  
mode. After this you will need to reset your setup parameters  
(speaker settings, delay settings, channel settings, etc.).

Techno Tidbits and Problem -solving  
THX  
TM  
THX is a Lucasfilm, Ltd. program dedicated to  
maximum accuracy in movie presentation. Movie  
sound tracks are recorded in large movie dubbing  
stages using movie theater equipment. For a sound  
track to be presented accurately in your home,  
special technologies are required. In your home the  
room is much smaller and has a bright sound, the  
speakers are very different and there are only six of  
them, plus, you sit much closer to each one of those  
speakers. Because of these differences we often  
miss the power and emotion that thrills us in a good  
movie. Now Pioneer and THX have teamed up to  
bring the full glory of accurate cinema sound to the  
comfort and convenience of your home.  
Tim bre Matching  
: When recording a sound track  
it is very important that the surround sounds move  
smoothly and seamlessly around the theater. It is  
very distracting when sounds seem to jump from  
speaker to speaker.  
Timbre Matching helps to smooth the movement of  
the surround sounds even though you are using only  
two speakers.  
TM  
Bass Peak Level Manager  
: Some Dolby Digital  
and DTS soundtracks can produce bass peaks that  
are undesiable in a home theater environment. The  
Bass Peak Level Manager allows you to set the  
maximum peak levels appropriate to your system.  
(Set this function according to the bass peak level  
instructions on page 35.)  
Re-Equalization TM : In a theater the room is very  
large and dead sounding, you sit a long way back  
from the speakers and the speakers themselves are  
very specialized. Because a sound track recorded in  
this dead sounding space when it is played at home  
it sounds overbright. THX Re-Equalization adjusts for  
this difference in a very precise way.  
TM  
Loudspeaker Position Tim e Synchronization  
This feature allows you to adjust for the difference in  
the distance from each individual loudspeaker to the  
listening position. Doing this ensures that all the  
speakers operate in precise synchronization  
improving the seamless nature of the soundfield.  
(Set this function according to the channel delay  
instructions on page 31.)  
:
TM  
Dynam ic Decorrelation  
: When a sound track  
sends mono sound to the surround speakers it often  
seems to be coming come from one side instead of  
from all around you as it would in a theater. Dynamic  
Decorrelation helps to correct this inaccuracy.  
MPEG Audio (VSX-D938TX only)  
MPEG is an audio encoding system which delivers high quality audio for music and movies. By removing  
frequencies which are out of the human hearing range, the sound is then compressed to enable the  
transmission of mono, stereo, or multichannel (5.1 and 7.1) audio in a single bitstream which is why it has  
become a standard audio format for DVD an personal computers. The composition and versatility of MPEG audio  
also ensures that the presentation of a multichannel soundtrack will sound appropriate on everything from a 7.1  
channel surround sound home theater setup to a mono televition set. Above all, MPEG audio is designed to be  
compatible with past and future MPEG audio versions, which means that future versions of MPEG audio will be  
compatible with decoders currently being produced (the signal is merely reconfigured to fit the number of  
channels available in a system).

Pow er cord CAUTION!  
Maintenance of External Surfaces  
Handle the power cord by the plug. Do not pull  
out the plug by tugging the cord and never  
touch the power cord when your hands are  
wet as this could cause a short circuit or  
electric shock. Do not place the unit, a piece of  
furniture, etc., on the power cord, or pinch the  
cord. Never m ake a knot in the cord or tie it  
with other cords. The power cords should be  
routed such that they are not likely to be  
stepped on. A dam aged power cord can cause  
a fire or give you an electrical shock. Check the  
power cord once in a while. When you find it  
dam aged, ask your nearest PIONEER
