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 can fully control the keypads,
“learn” the source's remote control codes (including those from other
manufacturers) and change source input on the amplifier etc.
On the front panel display of the 840A 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).

The 840A 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 RS232 port is also featured which allows the
840A to be controlled by C.I. systems.
In addition the units feature '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.
