540A/640A V2.0 Integrated amplifier

MULTI-ROOM

The Azur V2.0 amplifiers feature Incognito ReadyTM / A-BUSTMReady outputs, allowing multi-room capability. One or two amplified keypads (and an external PSU power supply) 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 via Cat5/5e cables and no mains connection is required in the secondary rooms.

The keypads operate independently of the amplifier in terms of volume/bass/treble etc and can be independently turned on and off, however 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 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. 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 Incogntio LR10 can fully control the keypads, “learn” the source's remote controls and change source input on the amplifier etc.
