Rear panel connections
Power On/Off
Switches the unit on and off.
AC 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.
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.
IR (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.
Control 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.
RS232C
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.
A-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.
Input 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.
Input 1/Input 2 Balanced/Unbalanced switch
Use to select the connection type for Input 1/Input 2.
Inputs 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.
Rec In (Input 8)
Connect to the output sockets of a Tape/MD player or other devices that
support recording.
Rec Out 1/2
Connect to the input sockets of your recording device.
Flat/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.
Sub Out
Connect to the input on an active subwoofer if required.
Balanced Pre Out
For connection to the balanced inputs of a power amplifier that support
this type of connection.
Pre Out
For connection to the unbalanced inputs of a power amplifier.
