Plug Fitting Instructions (UK Only)

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:

The wire which is coloured BLUE must be connected to the terminal which is marked with the letter ‘N’ or coloured BLACK.

The wire which is coloured BROWN must be connected to the terminal which is marked with the letter ‘L’ or coloured RED.

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.

Thank you for taking the time to read this manual; we do recommend you keep it for future reference.

Matthew Bramble, Cambridge Audio Technical Director and the 840E/840W design team

Standby/On

Switches the unit between Standby mode (indicated by dim power LED) and On (indicated by bright power LED). Standby is a low power mode where the power consumption is less than 30 Watts. The unit can be left in Standby mode when not in use. If the unit is not going to be used for a long period of time it should be switched off via the Power On/Off switch on the rear panel.

Note: As default the 840E ramps the volume up or down when switched on and when going into Standby mode. This feature can be turned off if desired; please refer to the ‘Pre-amplifier setup’ section of this manual for more information.

Phones

Allows for the connection of stereo headphones with a ¼" Jack plug. Headphones with an impedance of between 32 and 600 ohms are recommended. When the headphones are connected, the loudspeaker relays are released switching off the output to the loudspeakers (speakers A and B).

Mode

Press to switch between Volume, Balance, Bass and Treble modes. Press and hold to to enter the 840E System Configure menu.

Infrared sensor

Receives IR commands from the supplied Azur remote control. A clear unobstructed line of sight between the remote control and the sensor is required.

& Input select buttons

Push the appropriate input selection button to select the source component that you wish to listen to (highlighted by a solid circle on the display). The signal selected is also fed to the Rec Out sockets so that it may be recorded. The input should not be changed whilst recording.

Display

LCD used to control the 840E. Please refer to the ‘Operating instructions’ and ‘Pre-amplifier setup’ section of this manual for more information.

Direct

This control gives the audio signal a more direct path by bypassing the tone control circuits for the purest possible sound quality.

The Bass/Treble icon ( ) appears in the display when the bass and treble circuit is active (in circuit) and is not present when they are bypassed.

Note: Direct can be set on or off individually for each input. This setting is recalled each time a source is selected.

Volume

Use to increase/decrease the level of the sound from the outputs of the amplifier. This control affects the level of the loudspeaker output, the pre-amp output and the headphone output. It does not affect the Tape Out connections.

As the 840E uses a very high quality passive resistor ladder switched by relays to achieve volume and balance, audible control clicks can be heard from the unit when the volume or balance is adjusted.

The Volume control is also used in navigating the 840E System Configure menus on the front panel display.

Please refer to the ‘Operating instructions’ section of this manual for more information on some functions of these buttons.

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.

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.

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,

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.

Make sure the Balanced/Unbalanced switch for Inputs 1 and 2 are set to the connection type you wish to use.

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.

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).

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.

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).

840E

840W

Output connections - Balanced

The diagram below shows the 840E connected to an 840W using the Balanced Audio inputs via three-pin XLR connectors.

When using balanced (XLR) connections, the Left and Right Input Type switches on the 840W must be in the ‘Balanced’ position.

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.

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).

Note: In this configuration the 840W must be set to Stereo mode.

840E

840W

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).

The diagram below shows the 840E pre-amplifier connected to an Azur 840W power amplifier and a pair of loudspeakers.

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.

840W

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.

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.

The example below uses balanced connections from 840E to each 840W, unbalanced connections can also be used and the principle is the same.

Important! 840W settings

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.

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

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.

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.

Balance, Bass, Treble

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.

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.

Direct

With a well produced CD and a good system the tone controls are unnecessary and can be switched out by pressing the Direct button:

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 compensate. To use the tone controls press the Direct button so that the Bass/Treble icon ( ) lights in the display indicating that they are active and direct mode is Off.

The 840E stores whether Direct mode is on or off for each input individually. For example it is possible to have the tone controls automatically active for the Tuner source but not the CD source.

Pre-amplifier setup

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

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.

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 ramp, Volume display, and Fixed input gain.

To exit the System Configure menu and its sub-menus, press the Mode button again.

LCD brightness

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.

Volume ramp

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.

Volume display

To change the volume display from decibels (-95 to 0dB) to arbitrary volume units (0 to 96 units) select VOL DB in the System Configure menu. Press the input select button to turn off the volume in decibels. Press the Mode button to exit.

Front IR

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.

Input gain trim

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.

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.

Surround sound source e.g. 540D V2 DVD player

Stereo source e.g. 840C CD player

Pre-amplifier setup continued

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.)

Also, this feature can be used to integrate an AV Receiver which has preamp outputs (such as our own 540R or 640R models) with the 840E.

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.

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.

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.

To set a fixed volume for a source, select FIXED INP in the System Configure menu:

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.

On/Off control menu

When going in/out of Standby mode the 840E can automatically turn on and off other connected Cambridge Audio Azur models that have control bus sockets. For this feature to work the units must be connected together (see diagram) by RCA/phono leads. The Control Bus sockets are colour-coded orange on the rear panels of compatible Azur models. Connect the Control Bus Out from the 840E to the Control Bus In on another Azur model (e.g. 840W). Continue the chain to other Azur models if required.

Now while the 840E is on press and hold the Standby/On button until ON/OFF CTR appears on the display:

Select the connected Azur models by pressing the appropriate input select button. For example, CA XXXC for an Azur CD player (740C, 840C), CA XXXD for an Azur DVD player, CA DAB T for an Azur DAB tuner etc.

Press ON & OFF to scroll through the options of ON (turns all Azur units on only), OFF (turns all Azur units into Standby only) or ON & OFF (turns all Azur units on and into Standby mode).

Press OK to confirm and exit.

Connections to the 840E Incognito Ready / A-BUS Ready outputs are made by Cat-5 cable (terminated with an RJ45 jack plug). The RJ45 plug must be wired to the EIA/TIA 568A wiring standard:

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 minijack to mini-jack lead can be used. Commands received by the keypads can now be sent back to the source equipment via the 840E.

It is then possible to control the source equipment from the remote rooms by using the source equipment's own remote controls or through a learning remote. The Incognito LR10 Learning Remote can fully control the keypads, “learn” the source's remote control codes (including those from other manufacturers) and change source input on the 840E etc.

On the front panel display of the 840E the extra multi-room zones are indicated by a circle outline next to the input source (see Fig. 1). When listening to the same source, the circle outline and solid circle overlap (see Fig. 2).

Fig. 1 - One or both keypads are listening to a different source (Input 2)

to the amplifier (Input 1).

Fig. 2 - One or both keypads are listening to the same source (Input 2)

The 840E features Incognito Ready/ABUS Ready outputs, allowing multi-room capability. One or two amplified keypads can be plugged into the 840E (using Cat5/5e cable and RJ45 plugs) to provide multi-room audio in one or two secondary rooms or zones. The keypads are powered by an external PSU (also required) through the Cat5/5e cables and no mains connection is required in the secondary rooms.

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.

A-BUS is a standard that allows compatibility between different manufacturers equipment, so A-BUS compatible keypads from other manufacturers can also be used. If used with our own Incognito KP10 keypads, there are some extra features such as the ability to change source on the 840E from the keypad (EU model shown here):

840Eazur

ENGLISH

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.

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.

An RS232C port is also featured which allows the 840E to be controlled by C.I. systems.

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:

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.

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.

A full code table and RS232 protocol for this product is available on the Cambridge Audio website:
