Cambridge Audio 840A - Manual (Page 18)

The 840A features Incognito Ready TM / A-BUS TM Ready outputs, allowing
multi-room capability. One or two amplified keypads can be plugged into
the amplifier (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 840A 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 be used. If used with our own Incognito KP10
keypads, there are some extra features such as the ability to change
source on the amplifier from the keypad.
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 amplifier.
