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.

Custom installation (C.I.) use

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	PassThru	IR
different C.I. configurations. When the 740A is used in a	ControlBus	FrontPanel	Reserved	Reserved
cupboard (or when using routed IR) it may be desirable to
disable the Front Panel IR by setting the dip-switch to ‘Off’.
	Off

By default, all Cambridge Audio source equipment loop the

On

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.
