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):

Order of selection: 1. Input 1

2. Input 2

3. Input 3

4. Input 4

5. Input 5

6. Input 6 (Tape)

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).
