Be sure to insert each power cord securely. To prevent hum and noise, do
not bundle the interconnect leads with the power cord or speaker leads.
For any service, in or out of warranty, please contact your dealer.
Cleaning
Plug Fitting Instructions (UK Only)
To clean the unit, wipe its case with a dry, lint-free cloth. Do not use any
cleaning fluids containing alcohol, ammonia or abrasives. Do not spray
an aerosol at or near the unit.
The cord supplied with this appliance is factory fitted with a UK mains plug fitted
with a 5 amp fuse inside. If it is necessary to change the fuse, it is important that
a 5 amp one is used. If the plug needs to be changed because it is not suitable for
your socket, or becomes damaged, it should be cut off and an appropriate plug
fitted following the wiring instructions below. The plug must then be disposed of
safely, as insertion into a mains socket is likely to cause an electrical hazard.
Should it be necessary to fit a 3-pin BS mains plug to the power cord the wires
should be fitted as shown in this diagram. The colours of the wires in the mains
lead of this appliance may not correspond with the coloured markings identifying
the terminals in your plug. Connect them as follows:
Battery disposal
Please dispose of any discharged batteries according to local
environmental/electronic waste disposal guidelines.
Loudspeakers
Before making any connections to loudspeakers, make sure all power is
turned off and only use suitable interconnects.
The wire which is coloured BLUE must be
connected to the terminal which is marked
with the letter ‘N’ or coloured BLACK.
Servicing
The wire which is coloured BROWN must be
connected to the terminal which is marked
with the letter ‘L’ or coloured RED.
These units are not user serviceable, never attempt to repair,
disassemble or reconstruct the unit if there seems to be a problem. A
serious electric shock could result if this precautionary measure is
ignored. In the event of a problem or failure, please contact your dealer.
The wire which is coloured GREEN/YELLOW
must be connected to the terminal which is
marked with the letter ‘E’ or coloured GREEN.
If a standard 13 amp (BS 1363) plug is used, a 5 amp fuse must be fitted, or if any
other type of plug is used a 5 amp fuse must be fitted, either in the plug or adaptor,
or on the distribution board.

Thank you for purchasing this Azur 840E Pre-Amplifier. We hope that
you will enjoy many years of listening pleasure from it.
Cambridge Audio has taken the Azur 840 series to its peak with the
introduction of two new models – the 840E Pre-Amplifier and 840W
Power Amplifier. The 840E is a high-end pre-amplifier which uses
Cambridge Audio’s new proprietary TerraPin™ modules for unprecedented
audio fidelity, forming the perfect partner for the accompanying 840W
power amplifier.
Other features include the use of precision resistor ladders switched by
gold plated relay contacts for the volume and balance controls rather
than the more common solid-state or volume potentiometer schemes.
Volume is controllable in 1 dB steps over most of the range, giving very
fine control, an accurate logarithmic law and superbly accurate channel
balance. Input switching is also by high quality gold contact relays.
Inputs 1 and 2 feature balanced inputs using XLRs giving optimal
performance with equipment such as the matching 840C Upsampling
CD player which feature balanced outputs.
The casework combines massive structural rigidity with careful damping
and control of acoustic resonance. An Azur Navigator remote control is
also provided, giving full remote control in an attractive and easy to use
handset.
We have also included support for multi-room use. By plugging in one or
two external Cambridge Audio Incognito keypads and a power supply
unit, this unit can become the hub of a simple multi-room system. In
addition, Control Bus Input/Output, IR Emitter Input, Trigger In/Out and
RS232 control are featured making it easy to integrate the 840E into a
Custom Installation system if desired.
Your pre-amplifier can only be as good as the system it is connected to.
Please do not compromise on your source equipment, power amplifier
or cabling. Naturally we particularly recommend models from the
Cambridge Audio Azur range, in particular the matching 840W Class
XD™ Power Amplifier. These have been designed to the same exacting
standards as this pre-amplifier. Your dealer can also supply excellent
quality Cambridge Audio interconnects to ensure your system realises its
full potential.
Make sure you register your purchase.
Thank you for taking the time to read this manual; we do recommend
you keep it for future reference.

Trigger In, Out/Thru
For Custom Install use, the 840E can be turned on and off (i.e. brought
in and out of Standby mode) by the presence of 5-12V DC at the Trigger
input. A trigger input will also produce an internally generated 12V DC
trigger output at the Output/Thru connection. Turning the 840E on from
the remote/front panel also produces a 12V DC trigger output at the
Output/Thru connection. This can be used to turn on/Standby a
connected 840W power amplifier if desired. Refer to the ‘Power syncing’
section of this manual for more information.

Input (Source) connections
Inputs 1 and 2 on the 840E feature either unbalanced (phono/RCA) or
balanced (XLR) connections. The 840E is designed to work at its highest
performance when a balanced interconnect is used.
using a three-wire connection. One signal wire (the hot or in-phase)
carries the normal signal, while other (the cold or phase-inverted)
carries an inverted version. The balanced input senses the difference
between the two lines to give the wanted signal. Any noise voltages that
appear identically on both lines (these are called common-mode
signals) are cancelled by the subtraction.
The diagrams below shows the 840E pre-amplifier connected to an Azur
840C CD player in unbalanced (Figure 1) and balanced (Figure 2)
configurations. The 840E can also be connected to non Cambridge
Audio sources with balanced outputs.
Make sure the Balanced/Unbalanced switch for Inputs 1 and 2 are set
to the connection type you wish to use.
Balanced connections in an audio system are designed to reject
electrical noise, from power wiring etc, and also the effects of noise
currents flowing through ground connections. The basic principle of
balanced interconnection is to get the signal you want by subtraction,

Power syncing (On/Standby control)
When going in/out of Standby mode the Azur 840E pre-amplifier can (if
desired) automatically control the 840W when connected via the Control
Bus sockets (the Control Bus sockets are colour-coded orange on the
rear panels of compatible Azur models). For this feature to work the
units must be connected together by RCA/phono leads. No futher setup
is necessary.
Note: The 840E features a Trigger Out which can alternatively be used
to control the 840W’s Standby/On status if desired. Again, the
procedure is simply to connect the two units together (using a 3.5mm to
3.5mm mono mini-jack lead in this case).
Control Bus is the recommended method when using an 840E and other
Cambridge Audio equipment with Control Bus In/Out.
Connect the Control Bus Out from the 840E to the Control Bus In on the
840W. Continue the chain to other Azur models if it is required to sync
more units (refer to the 840E’s own manual for more information as this
requires some setup).
Trigger In/Out can be useful if the 840W (and indeed 840E) is desired
to be controlled by other equipment that features trigger outputs
(Custom install and/or Multi-Room Systems etc).

azur 840E
Output connections - Unbalanced
The 840E features both balanced (XLR) and unbalanced (RCA/Phono)
output connections. For the best quality we recommend you use the
balanced output with power amplifiers that feature this connection
(such as our own 840W Class XD power amplifier).
Before making any connections to the loudspeakers, make sure all
power is turned off and only use suitable interconnects (e.g. banana
plugs). Ensure that the positive (+) and negative (-) connections are
matched.
The diagram below shows the 840E pre-amplifier connected to an Azur
840W power amplifier and a pair of loudspeakers.
Your loudspeaker may have more than one pair of connecting terminals;
LF (Low Frequency) and HF (High Frequency). For single-wiring it is
recommended to connect to the LF terminals. The metal strip
connecting the low-frequency terminals to the high-frequency terminals
must not be removed (only to be removed for a bi-wiring system).
When using unbalanced (phono/RCA) connections, the Left and Right
Input Type switches on the 840W must be in the ‘Unbalanced’ position.
Note: In this configuration the 840W must be set to Stereo mode.

Mono Bridged connections
The matching Azur 840W power amplifier features Mono and Bridged
Mono settings that allow two (or more) 840Ws to be used as mono-blocs
for high end systems. Below is an example using two 840Ws in Bridged
Mono with an 840E.
Important! 840W settings
Before making any connections to the loudspeakers, make sure all
power is turned off and only use suitable interconnects (e.g. banana
plugs). Ensure that the positive (+) and negative (-) connections are
wired as shown in the diagram.
In Bridged Mono mode each 840W drives one speaker across its output
channels acting as a 500W mono amplifier instead of a 200wpc stereo
one. One 840W drives the left speaker and the other the right. See the
840W manual for full details on Bridged Mono and other possible
combinations.
When using balanced (XLR) connections, the Left and Right Input Type
switches on the 840W must be in the ‘Balanced’ position. When using
unbalanced (phono/RCA) connections, the Left and Right Input Type
switches on the 840W must be in the ‘Unbalanced’ position.
The example below uses balanced connections from 840E to each
840W, unbalanced connections can also be used and the principle is
the same.
Only use the Left Inputs on the 840W for Bridged operation.
In this configuration the Stereo/Mono switch on the 840W must be set
to ‘Mono’ and the Mono mode switch must be set to ‘Bridged’.

Operating instructions
Pre-amplifier setup
The 840E has a custom-made display on the front of the unit that shows
the current status and allows you to access the 840E System
Configuration menus. Here you can adjust the listening settings of the
amplifier to personal preference. The menu system is easy to navigate
and control, simply by using the input select buttons to turn a feature on
(solid circle) or off (no circle) and the volume control knob to
increase/decrease settings.
The 840E features many advanced settings that allow its use to be
customised to user preference. The inputs can be named to reflect the
actual source units you have, each input can be trimmed so that each
sounds the same in terms of loudness when you switch between them
and other options.
Changing input names / source naming
Volume

Volume
Press and hold the relevant input select button for four seconds to
change its name. For example, if Input 1 is a CD player, name it “CD” etc.
Letters are selected by turning the volume control to scroll through the
available characters. Press LEFT or RIGHT to select which character you
wish to edit. Press EXT CHAR to access an extended character set. Press
OK to confirm and exit the input name change menu.
Volume
Adjust the volume control knob on the front panel (or using the remote
control). The display will show the change in volume in decibels (dB).
‘OdB’ indicates maximum volume while lower volume settings progress
into the negative range. This can also be changed to arbitrary volume
units (0-96) in the System Configure menu.

Press and hold the Mode button to access the System Configure menu.
The menu options are LCD brightness, Front IR, Input gain trim, Volume

Press the Mode button to scroll through the options of Balance, Treble
or Bass modes. BALANCE, TREBLE or BASS will appear on the display
depending on which mode you have entered. Adjustments can then be
made using the volume control. This allows subtle adjustments to the
tonal balance of the sound. These modify the sound through your
loudspeakers and the Pre-Out sockets only; they do not affect the
signals sent through the Tape Out connections.
To exit the System Configure menu and its sub-menus, press the Mode
button again.

Press the Mode button again to return to Volume mode or wait 5
seconds for the 840E to automatically exit and return to Volume mode.

Volume
With a well produced CD and a good system the tone controls are
unnecessary and can be switched out by pressing the Direct button:
In the System Configure menu press the LCD input select button to scroll
through bright/dim/off settings for the front panel display. Press the
Mode button to exit.

This completely removes them from the signal path for maximum
fidelity. If the musical recording is of poor quality or other factors are
affecting the sound quality, you can adjust the tone controls to

The 840E automatically ramps the volume down when going into
Standby mode and up when coming out of Standby mode. To turn this
feature off, press the VOL RAMP input select button in the System
Configure menu and set to off. Press the Mode button to exit.
Bass/Treble icon (

Pre-amplifier setup continued
Front IR
Fixed level inputs
Any input of the 840E is able to be set for fixed gain. Whenever this input
is selected the gain will automatically go to this value and will not be
adjustable by the volume control. This can be useful with sources that
have their own built in volume control (such as some set-top boxes etc.)
Mode
Volume
Also, this feature can be used to integrate an AV Receiver which has pre-
amp outputs (such as our own 540R or 640R models) with the 840E.
Used in conjunction with Custom Installation (C.I.) systems or IR
repeater systems, it may be desirable to disable the front panel IR by
setting FRONT IR to off (press the input select button to turn off). Press
the Mode button to exit.
The front Left and Right pre-amp outputs of the AV Receiver are simply fed
to any desired input of the 840E and that input set for fixed gain. The AV
receiver is then wired to the various surround speakers whilst the 840E/W
drives the Front Left and Right.
Input gain trim
The 840E/W can then be used for Stereo sources as normal for best
sound quality. When it is desired to decode surround sound, select the
input chosen for fixed gain on the 840E. Now the AV Receiver can be used
to decode any of it’s surround sound sources. It will have control of the
volume of all channels and the 840E’s own volume control will be
disabled.
The relative levels of the inputs can be adjusted by gain trim. This allows
each to be adjusted so that each sounds the same in terms of average
loudness when you switch between them. Pick the loudest sounding
source and trim its level until it matches the average perceived level of
the others. Repeat this process if other sources also stand out as louder
than the average.
You may wish to re-name the fixed level input as “AV mode” or similar on
the 840E. As the gain can be fixed to any value it is easy to match the
level of the 840E to that of the other AV channels.
Mode
To set a fixed volume for a source, select FIXED INP in the System
Configure menu:
Volume
Mode
To set the input gain trim for each source, select INP TRIM in the System
Configure menu. Select the input required and use the volume control to
set the gain between 0 and -12 dB (the available range is restricted if
the volume is set very low). Press the Mode button to exit.
Volume
Select the input required and set the fixed gain using the volume control
(the OFF setting does not disable the input but leaves the input gain
subject to the volume control which is the default setting). When a
source has a fixed input, the balance is always set to neutral. Press the
Mode button to exit.

To allow control of your source equipment from the remote rooms an IR
emitter (IR10) is plugged into one of the IR outputs on the rear of the
unit and then attached over the IR window of the source unit.
Alternatively, on our own products that feature IR emitter Inputs, a mini-
jack to mini-jack lead can be used. Commands received by the keypads
can now be sent back to the source equipment via the 840E.

Fig. 2 - One or both keypads are listening to the same source (Input 2)
as the amplifier (Input 2).
The 840E is Incognito Ready Type II, which means the keypads can
operate independently of the amplifier in terms of volume/bass/treble
etc, be independently turned on and off, and can also listen to a
different source from that which is currently selected on the amplifier.
However, both keypads can only listen to the same source.

The 840E features a Control Bus input/output that
allow un-modulated remote control commands
(positive logic, TTL level) to be received electrically
by the unit and looped to another unit if desired.
These control commands are typically generated

by custom installation (multi-room) systems or remote IR receiver
systems. The Control Bus sockets are colour-coded orange.
There is no sound
Make sure the unit is not in Standby mode.
An IR Emitter Input is also provided that allows modulated IR remote
control commands to be received electrically by the unit. Commands on
this input operate the unit only and are not looped out demodulated on
the Control Bus Output.
Check that source component is properly connected.
Check that Input 8 (Rec In) is not switched on (unless a tape input is
required).
An RS232C port is also featured which allows the 840E to be
controlled by C.I. systems.
Check that your speakers are properly connected.
Make sure unit is not in mute mode.
In addition the unit features ‘direct’ IR/Control codes as well as toggle
codes for some of their features to simplify programming custom
installation systems. Special direct On/Off and Mute commands can be
accessed on the supplied remote control for teaching into C.I. systems
as follows:
There is no sound on one channel
Ensure that balance control is in the correct position.
1. Press and hold the Standby/On button. The remote first generates it's
standby (toggle) command. Keep the button held down, after 12
seconds an amplifier “On” command will be generated. If the button
is kept held down for a further 12 seconds, an amplifier player “Off”
command is generated.
Check speaker connections.
Check interconnects.
There is a loud buzz or hum
Check turntable or tone arm for ground and connection lead fault.
2. Press and hold the Mute button. The remote first generates it's mute
(toggle) command. Keep the button held down, after 12 seconds a
“Mute on” command will be generated. If the button is kept held
down for a further 12 seconds, a “Mute off” command is generated.
Ensure no interconnects are loose or defective.
Ensure that your tape deck/turntable is not too close to the unit.
A full code table and RS232 protocol for this product is available on the
Cambridge Audio website:
Unable to make or play tape recordings
Check that Input 8 (Rec In) and Rec Out have been connected correctly.
There is weak bass or diffused stereo imaging
Ensure that speakers are not wired out of phase.
The remote handset will not function
Check that the batteries have not expired.
Ensure that nothing is blocking the remote sensor.
