ULTRALINK UL2000M
1. INTRODUCTION
Thank you very much for expressing your confidence in the ULTRALINK Series by purchasing this unit.
With the UL2000M from BEHRINGER, you have acquired a modern, high-performance wireless
transmission system.
Thanks to its amazing set of features, you can use the UL2000M in all situations in which the highest
sound quality and mobility are a must, e.g. live concerts, events and video productions.
Depending on your local wireless transmission regulations, you can use up to 20 systems simultaneously.
The ULR2000 receiver uses two complete receiver channels, which are automatically tuned to the
same frequency. This function requires no attention from the user. This so-called True Diversity
technology enables outstanding disturbance-free signal transmission. This way, you can profit from
the greatest freedom of movement and can fully concentrate on what’s essential: your music.
The IRC compander system guarantees an extremely wide transmission dynamic range. Since vocals
benefit from this characteristic most, the UL2000M is ideal for such applications.
The microphone features a high-quality Panasonic® capsule with a cardioid polar pattern. Therefore, it primarily
picks up the sound from the front and less so from the sides. The signal entering the microphone from the
back is mostly suppressed. This way, the microphone’s propensity to creating feedback is very negligible,
even in live situations.
The ULTRALINK Series equipment features 3 factory presets, each with 8 permanent, interference-free
channels. This allows you to use several systems in parallel without them influencing one another. Additionally,
you have the option of storing 8 of your own frequencies in a user preset, thus individually addressing your
own needs.
Determining which microphone is assigned to which receiver is done either by observing the transmission
channel in the display or by comparing the transmission frequency. In addition, the ULTRALINK equipment
from BEHRINGER leaves you the option to color-code your gear for easy identification.
Beyond that, both units feature other useful functions, such as Scan and Auto Mute. This way, no wishes are
left open during practice or in live situations.
ꢀ
The following instructions are intended to familiarize you with the unit’s controls, so that
you can learn all of its functions. After having thoroughly read these instructions, store them
in a safe place for future reference.
1.1 Before you get started
1.1.1 Shipment
The UL2000M was carefully packed at the factory to assure secure transportation. Should the condition
of the cardboard box suggest that damage may have taken place, please inspect the unit immediately
and look for physical indications of damage.
ꢀ
Damaged units should NEVER be sent directly to us. Please inform the dealer from whom
you acquired the unit immediately as well as the transportation company from which you
took delivery of the unit. Otherwise, all claims for replacement/repair may be rendered invalid.
ꢀ
ꢀ
ꢀ
Always use the original packaging to avoid damage due to storage or shipment.
Never leave children unsupervised with the unit or its packaging.
Please dispose of all packaging materials in an environmentally friendly manner.
1.1.2 Registration
Before powering up the unit for the first time, you have to register it with your local postal/
telecommunication authority! Additional information is available there.
1.1.3 Initial operation of the receiver
Assure adequate ventilation and never place your ULR2000 receiver on top of an amplifier or near
radiators to avoid overheating.
The wall power unit (model: E-SPS1) included in the delivery supplies the power to your ULR2000. Only use
the external power supply delivered with the unit!
The interchangeable AC plugs can be swapped at any time, adapting to various socket types in
different countries (Fig. 1.1).

Keep the button (A) on the front side of the power supply pressed to release the plug. Pull the
plug out and let go of the button.
1.
2.
Insert a different plug into the power supply unit. The plug is securely snapped into place when you
hear a click.
Fig. 1.1: Swapping plugs on the switching power supply unit
1.1.4 Initial operation of the microphone
The ULM2000 microphone requires one or two 9V batteries. Of course, using only one 9V battery
decreases the effective uptime. When using only one battery, it does not matter which of the two
battery compartments you use. Either one will work.
ꢀ
When running the unit on two batteries, please make sure that both batteries are equally
fresh. Therefore, whenever changing batteries, always use two brand-new batteries.
When the battery is nearly depleted, the LED located on the bottom of the microphone will start to blink
rapidly. Simultaneously, a special inaudible signal is sent to the ULR2000 receiver, and “LowBat” is shown in
its display. To assure dependable operation of the transmitter-receiver system, change the transmitter batteries
as soon as possible after seeing the “LowBat” message.
To change the transmitter (mic) batteries:
1.
2.
Unscrew the bottom end of the microphone and pull out the battery compartment.
Be sure to insert the batteries according to polarity. Labels for battery orientation are found in
each battery holder of the compartment.
3.
4.
Keep the microphone in the usual upright position and begin by placing the bottom battery.
Remove the base plate in order to connect the battery to the contacts. Re-insert the plate to
ensure the battery fits securely.
5.
6.
To place the second battery, turn it upside down. Insert the battery with the bottom end first into
the open side of the holder by pushing the base plate, which is fixed to a spring, into the
microphone body. Then connect the battery to the contacts (pay attention to the correct polarity).
Screw the bottom end of the microphone back on.
1.1.5 Online registration
Please do remember to register your new BEHRINGER equipment right after your purchase by visiting
warranty carefully.
Should your BEHRINGER product malfunction, our goal is to have it repaired as quickly as possible.

2. ULR2000 RECEIVER
2.1 Control elements and connections
In this chapter, different control elements of your ULR2000 will be described, explained in detail, and
you will get useful information on how to use them.
2.1.1 The front
Fig. 2.1: ULR2000’s front side
POWER
To power the ULR2000 on or off, keep the POWER button pressed for at least 2 seconds. To disconnect
the unit from the mains, please unplug the power supply. Make sure the wall power supply is easily
accessible whenever you use the ULR2000. If you mount it in a rack, make sure that you can easily
unplug the wall power supply or an all-pole disconnect switch.
ꢀ
ꢀ
Please keep in mind: The POWER switch does not entirely separate the unit from the mains.
Please disconnect the power cord from the mains if you won’t be using the unit for a while.
VOLUME
The output signal level of the receiver can be set using the VOLUME control. If you run the ULR2000
in a setup with balanced connections, a maximum signal level of 12.5 dBu is possible; in setups with
unbalanced connections, the maximum signal level is 6.5 dBu.
We would like to point out that high volume levels may cause distortion and high signal
levels in other equipment to which your ULR2000 is connected (e.g. mixing console or
headphones). High volume levels may damage your hearing and/or your headphones/
speakers. Please turn the VOLUME control all the way to the left (very low output signal)
before turning the ULR2000 on. Always make sure that an appropriate volume is set.
DISPLAY
All important parameters are shown in the display (ch. 2.1.2).
SET
The SET button has 2 functions:
ꢁ
ꢁ
Press this button to bring up the menu.
To confirm the values you set in the menu, press the SET button.
ꢁ UP and ꢂ DOWN
These two buttons let you navigate the menu and change the values shown in the display (e.g. frequency,
channel number, preset number).
If the ULR2000 is in the basic setting (menu not selected), pressing the ꢁ UP and the ꢂ DOWN
buttons changes the transmission channel within the selected preset.
The ꢁ UP and ꢂ DOWN buttons have a repeat functionality with many function (i.e. the action
is carried out perpetually if the button is kept pressed; for example, setting a carrier frequency
can be simplified this way).

COLOR CODE
Each BEHRINGER ULTRALINK transmitter can be color-coded using a color ring; this way you can
easily differentiate between multiple transmitters (set to different frequencies). To easily match a
transmitter to a receiver, you can also attach color-coded strips to each receiver.
ANTENNA
Two bar antennae can be connected to the ANTENNA 1 and ANTENNA 2 connectors.
2.1.2 Display
Fig. 2.2: Closeup of the ULR2000 display
(antenna symbol)
These two antenna symbols indicate which antenna signal is currently being processed. The left symbol
lights up when the signal from the left-hand antenna (ANTENNA 1) is stronger, and the right symbol
shows that the signal from the right-hand antenna (ANTENNA 2) is being processed.
RF LEVEL
The 8-level RF LEVEL display shows the reception strength of the carrier frequency (Radio Frequency)
on the ULR2000.
If not a single bar is shown, the carrier frequency is not being received. Bad reception is indicated with
1 - 3 bars; signal noise may be somewhat higher in this case. The more bars are shown, the better the
reception of the transmitter carrier frequency on the ULR2000.
AF
Similar to a distortion gauge on a mixer or an amplifier, the 8-level AF indicator shows how loud the
demodulated audio signal (Audio Frequency) is.
If the signal has no amplitude or if the amplitude is low, no bars are shown. The maximum undistorted
AF-level is received when 7 bars (and not 8!) light up.
ꢀ
Only when the audio signal is overdriving or when no RF signal can be received (the receiver
creates too much noise), 8 bars are shown in the LCD.
Alphanumeric display
All the values and letters relevant to the operation of your ULR2000 are shown in the 6-digit alphanumeric
display: for example, channel number, channel color, frequency and menu items.
CHANNEL
If the ULR2000 is in the basic setting (menu not selected), pressing the ꢁ UP and ꢂ DOWN buttons
changes the transmission channel within the selected preset.
If CHANNEL is lit, the individual channel numbers are shown (CHAN1, CHAN2, ...).
Also, when storing a user-selected frequency in the user preset, a channel number is entered.
FREQ MHz
If FREQ MHz lights up, changing the transmission channel using the ꢁ UP and ꢂ DOWN buttons
also displays the frequency of the selected channel.
ꢀ
If neither CHANNEL nor FREQ MHz are lit, the display is indicating the channel color
(BLUE, RED, ...) of the set channel. When storing a user-selected frequency in the user preset,
you will be asked to enter a channel color.

ULTRALINK UL2000M
MUTE
MUTE indicates that the ULR2000’s output is being muted.
If the received and demodulated AF starts getting weaker, the noise increases; the signal-to-noise
ratio gets smaller.
The SQUELCH menu item lets you enter a threshold value (in dB) for the signal-to-noise ratio. If this
ratio gets smaller than the threshold value, the receiver automatically mutes the signal (ch. 2.2.3).
2.1.3 The back
Fig. 2.3: ULR2000’s back
The power is supplied via a 12 V connector. A matching cable is included in the delivery.
ꢀ
If the power supply is interrupted (e.g. by removing the wall power supply), please wait at
least 10 seconds before restoring the power supply again. This avoids causing possible
damage to the unit.
Balanced XLR output.
Balanced TRS output.
GND
The unit can be earthed. Attach an earthing cable to the GND screw.

To do this, press the SET button; the scan is immediately interrupted. Now, you can either
start another scan (see lines 4 and 5), or the frequency shown can be stored (see lines 6, 7
and 8).
2.2.3 SQUELCH
With wireless signal transmission, restricted reception conditions may cause the transmission of additional
noise and interference. The Squelch function lets you adjust if the ULR2000 is muted under such conditions.
You can also enter the noise level that will trigger the mute function:
ꢁ
ꢁ
ꢁ
0 dB:
the receiver is not muted
low dB value:

ULTRALINK UL2000M
2.2.4 AUTO MUTE
If the transmitter is turned on, off, or is switched to another channel without first muting the receiver,
or if the transmission drops out due to weak batteries, audible noise will result. Even if the noise limiter
is enabled on the receiver (ch. 2.2.3), it still requires some time to react, and such noise can not be
suppressed safely.
To bridge this latency time, the ULR2000 offers a practical Auto Mute function:
ꢁ
When the ULM2000 is being turned off, when you are switching channels or during low-battery indication,
an inaudible send signal is being transmitted.
ꢁ
The ULR2000 recognizes this signal and automatically mutes the output before the transmitter is
actually turned off, switched to another channel or before it powers down on its own due to battery
charge being too low.
ꢀ
For the Auto Mute function to work, it has to be activated on both the transmitter and the
receiver!

2.2.7 PRESET
The ULR2000 lets you work with 4 presets, each with 8 channels.
Factory presets (Presets 2, 3 and 4)
In the ULR2000, there are 3 factory presets (each with 8 interference-free channels). That means that all 8
channels of one preset can run simultaneously with 8 different transmitters and receivers without causing
mutual interference.
The channels in the 3 factory presets are all assigned to different frequencies. This way, you can always
select a frequency range that assures the best signal transmission.
The following table shows which frequencies are stored in the factory presets.

Changing the channel when the transmitter is powered off
1.
Turn the selection switch to one of the values (1 - 8), corresponding to the desired channel number.
2.
If you turn on the transmitter, the channel you selected is automatically loaded.
ꢀ
If an invalid channel number was selected (0 or 9), the channel selected last remains selected.
3.2.3 Setting your own frequency
A carrier frequency in the range between 798.1 and 805.9 MHz can be freely selected. This frequency is
stored in a self-assignable user preset (Preset 1).
ꢀ
The carrier frequency can only be set in 25-kHz steps. The frequency you select has to be a
multiple of 25 kHz. If you select a frequency that is not a multiple of 25 kHz or does not lie in
the frequency range between 798.1 and 805.9 MHz, the ULM2000 gives off an error message
(the LED blinks quickly 5 times).
1.
2.
Engage MUTE. The transmitter can now be switched to the programming mode.
Turn the selection switch to 9 and confirm your selection by keeping the POWER button pressed for
about 2 seconds. The LED indicates confirmation by blinking once with medium tempo and blinking
once slowly. The transmitter is now in the programming mode and awaits the entry of a 6-digit frequency.
3.
Enter all 6 digits one after another in the following fashion:
ꢁ
Select the desired value on the selection switch, for example 4. If a valid value is selected, the
LED blinks quickly once as a confirmation. This way, you can be sure that a correct value is
entered (in regard to the frequency range and divisibility by 25 kHz) even before confirming your
selection.
ꢁ
ꢁ
Confirm your selection by briefly pressing the POWER button.
If the end frequency value you entered is valid, the LED blinks quickly once more. If the frequency
value is invalid, the LED blinks quickly 5 times, and the unit is no longer in the programming
mode. In this case, start anew with step 2.
After a brief interruption, a second blink code is given: the LED blinks corresponding to the value
selected (in this case, 4 times) with medium tempo.
ꢀ
ꢀ
The value 0 is indicated by a very short blink of the LED, and you will easily tell a
0 from a 1.
If no entry is made for more than 5 seconds (either on the selection switch or by pressing the
POWER button), the LED blinks quickly 5 times, and the programming mode is aborted.
After entering the 6 digits for the frequency value, enter another value to indicate the channel number under
which the frequency will be stored.
4.
Select a desired channel number on the selection switch, for example channel 2 (possible values: 1 - 8).
If a valid value is selected, the LED blinks quickly once to confirm. This way, you can be sure that a
correct channel number is being entered even before confirming your selection.
5.
6.
Confirm your selection by briefly pressing the POWER button.
When a valid value is selected, the LED blinks briefly again. When an invalid value is selected, the
LED blinks quickly 5 times and the unit is no longer in the programming mode. In this case, start anew
with step 2.
After a brief interruption, a second blink code is given: the LED blinks corresponding to the value
selected (in this case, 2 times) with medium tempo.

After a second blink pause, an additional blink code is given as a confirmation:
ꢁ
A successfully stored frequency is signaled with 2 slow blinks. The transmitter leaves the
programming mode.
ꢁ
If the LED blinks quickly 5 times, the frequency was not stored. In this case, start anew with step 2.
ꢀ
If no entry is made for more than 5 seconds (either on the selection switch or by pressing the
POWER button), the LED blinks quickly 5 times, and the programming mode is aborted.
8.
Disengage the MUTE switch.
ꢀ
A user-assigned frequency is automatically stored in the user preset (Preset 1)!
3.2.4 Preset
The ULM2000 lets you work with 4 presets, each with 8 channels.
Factory presets (Presets 2, 3 and 4)
In the ULM2000, there are 3 factory presets (each with 8 interference-free channels). That means that all 8
channels of one preset can run simultaneously with 8 different transmitters and receivers without causing
interference to one another.
The channels in the 3 factory presets are all assigned to different frequencies. This way, you can always
select a frequency range that assures the best signal transmission.
The following table shows which frequencies are stored in the factory presets.

7.
Disengage MUTE.
3.2.6 Auto Mute
If the transmitter is turned on, off or switched to another channel without first muting the receiver, or if the
transmission fails due to weak batteries, audible noise will result. Even if the squelch circuit is turned on at
the receiver end, it still requires some time to react, and such noise can not be suppressed safely.
To bridge this latency time, the ULM2000 offers a practical Auto Mute function:
ꢁ
When the ULM2000 is being turned off, when you are switching channels or during low-battery indication,
an inaudible send signal is being transmitted.
ꢁ
The ULR2000 recognizes this signal and automatically mutes the output before the transmitter is
actually turned off, switched to another channel or before it powers down on its own due to
battery charge being too low.

programming mode.
ꢁ
If the setting for Auto Mute could not be stored, the LED blinks quickly 5 times. In this case, start
anew with step 2.
7.
Disengage MUTE.
3.2.7 Turning the microphone off
To turn of the transmitter, keep the POWER button pressed for 2 seconds. A long blink confirms that
microphone is being turned off.
ꢀ
The transmitter stores the frequency and the channel settings. These parameters are restored
to these same values the next time you turn the unit on.
3.3 Status query
While you are using your microphone, you may want to check the “transmission channel,” “battery condition,”
“transmission frequency,” “preset,” “Mic Gain” and “Auto Mute” parameters. The status of these parameters
can be checked without having to turn the microphone off and back on.
3.3.1 Battery condition and transmission channel

3.5 ULM2000 level setting
ꢀ
To optimally set the level on your ULM2000, the High Gain or Low Gain setting has to be set
to the level of the signal being transmitted (ch. 3.2.5).
Adjust the gain control in the microphone channel of your mixing console so that the peak LED lights up only
occasionally or never at all. The EQ controls in the microphone channel should be set to mid-travel position
to start with. To get the sound you want, try changing the mic position relative to the sound source or even
move the microphone around in the recording room of your studio. Adjusting the angle at which walls face the
sound source can also be helpful. Only when the desired basic sound has been achieved should you start to
use equalizers and signal processors, if any at all (remember: less is often more!)

5. INSTALLATION
5.1 Installation information
ꢁ
Always make sure that the devices are not operated in direct proximity of large metallic surfaces
(radiators, metal racks, reinforced concrete walls and similar).
ꢁ
ꢁ
The devices should always be at a height of at least 1 m (3 ft.) off the ground.
To assure good reception in many different positions, we advise against having the antennae point at
a 90-degree angle. Instead, antennae should be arranged at an angle of no more than 40° in respect to
one another.
ꢁ
ꢁ
To assure interference-free reception, ideally there should be no large objects placed between the
transmitter and the receiver. Not only the size but also the type of material play a role in determining
how strong signal interference will be!
If you want to install your ULR2000 in a rack, please read the following chapter; there you can find all
the necessary information.

5.2 Installation in a rack
The ULR2000’s antennae are located in the front of the unit. This allows unproblematic installation
in a rack.
Each unit is delivered with a rack bracket and a connecting joint. This way, you can choose:
1.
If you wish to install only one unit in a rack, mount a rack bracket to one of the sides. In this case, you
will not need the included connecting joint. Now, install one side of the receiver into the rack.
2.
To install 2 receivers in a rack, first connect the two receivers to one another at the bottom using the
connecting joint. Mount one rack bracket on the left side of one unit and one rack bracket on the right
side of the other unit. Now, both ULR2000s can be installed in a rack.
ꢀ
To assure good reception, if possible, install the ULR2000 as high in a rack as possible, so
that the antennae protrude above the upper edge of the rack.
The ULR2000 requires one height unit (1 HE) for installation in a 19-inch rack. Please assure that there are
additional 10 cm (4 inches) of free space in the back for connecting cables.
For installation in a rack, use M6 machine screws and nuts.
Be sure that there is plenty of space around the unit for cooling and, to avoid overheating, please do not
place the ULR2000 on top of power amplifiers or other heat-emitting equipment.
If you wish to install more than 2 units in a rack, please make sure that there is enough space between them
(fig. 5.1). The lower unit’s antennae may not perturb against the upper unit’s antennae. Otherwise, they could
interfere with one another, causing a decrease in reception quality.
