ENGLISH

1Power On/Off

Switches the unit on and off.

2AC power socket

Once you have completed all connections to the unit, plug the AC power cable into an appropriate mains socket then switch on. Your unit is now ready for use.

3Trigger 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.

4IR (Infra-Red) Emitter In

Allows modulated IR commands from multi-room systems or IR repeater systems to be received by the unit. Commands received here are not looped out of the Control Bus. Refer to the ‘Custom installation’ section of this manual for more information.

5Control Bus

In - Allows un-modulated commands from multi-room systems or other components to be received by the unit.

Out - Loop out for Control Bus commands to another unit.

Also allows the 840E to turn on/off some Cambridge Audio units, including the matching 840W power amplifier. Refer to the ‘Power syncing’ section of this manual for more information.

6RS232C

The RS232C port allows external serial control of the 840E for custom install use. A full command set is available on the Cambridge Audio website at www.cambridge-audio.com. This port can also be used by Cambridge Audio service personnel for software updates.

7A-BUS™ Ready / Incognito Ready™ multi-room outputs

PSU In - Connect an Incognito PS5 to supply power to the connected multi-room keypads/speakers.

Keypad 1/2 - Connect one or two Incognito A-BUS KP10 keypads (or other A-BUS compatible keypads) using CAT5/5e cable. Incognito AS10 Active Ceiling Speakers can also be connected here.

IR - Four IR outputs for remote control of source equipment.

Please refer to the ‘Multi-Room’ section of this manual for more information on connections and set-ups.

8Input 1/2 Balanced Audio

Inputs 1 and 2 feature either unbalanced (phono/RCA) or balanced (XLR) connections. Either type may be used but not both at the same time. The balanced connection is the higher quality option and can reject noise and interference in the cable when used with other equipment that supports this function. An XLR connector is wired Pin 1 - Ground; Pin 2 - Hot (in-phase); Pin 3 - Cold (phase-inverted).

Use the Balanced/Unbalanced switch (Item 9) to select the connection type you wish to use. The unused input does not require to be terminated.

9Input 1/Input 2 Balanced/Unbalanced switch

Use to select the connection type for Input 1/Input 2.

10Inputs 1-7

These inputs are suitable for any 'line level' source equipment such as CD players, DAB or FM/AM tuners etc.

Note: These inputs are for analog audio signals only. They should not be connected to the digital output of a CD player or any other digital device.

11Rec In (Input 8)

Connect to the output sockets of a Tape/MD player or other devices that support recording.

12Rec Out 1/2

Connect to the input sockets of your recording device.

13Flat/200Hz LP switch

The 840E features a Sub output that is a separate mono mix created from the main pre-amp outputs. This output can have either a ‘Flat’ (i.e. full range, unfiltered) frequency response or a 200Hz Low Pass filter can be applied. Most Subwoofers feature built in Low Pass filtering and ‘Flat’ is usually the best setting. This setting does not affect the main outputs which are always full-range.

14Sub Out

Connect to the input on an active subwoofer if required.

15Balanced Pre Out

For connection to the balanced inputs of a power amplifier that support this type of connection.

16Pre Out

For connection to the unbalanced inputs of a power amplifier.
