The 740A features Incognito
Ready/A-BUS Ready outputs,
allowing multi-room capability. One
or two amplified keypads can be
plugged into the 740A (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 740A is Incognito Ready Type I, which means the keypads can
operate independently of the amplifier in terms of volume/bass/treble
etc, be independently turned on and off from the 740A and each other,
but they can only listen to the same source as selected on the amplifier.
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 740A from the keypad.
Connections to the 740A’s 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 740A.
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 740A etc.
For further details on the Incognito multi-room system please contact
your local Cambridge Audio dealer or visit www.cambridge-audio.com.

The 740A 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.
The 740A is also fitted with dip-switches which can be set for
different C.I. configurations. When the 740A is used in a
cupboard (or when using routed IR) it may be desirable to
disable the Front Panel IR by setting the dip-switch to ‘Off’.
By default, all Cambridge Audio source equipment loop the
Control Bus signals from ‘In’ to ‘Out’. If several units are used
in a complete loop, set the Control Bus Passthru dip-switch to ‘Off’.
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.
A full code table for this product is available on the Cambridge Audio
website at www.cambridge-audio.com.
