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 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.
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)
as the amplifier (Input 2).

The 840E features Incognito Ready/A-
BUS 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):
