INTRODUCTION Thank you for purchasing this Cambridge Audio Incognito product. Incognito is a cost-effective, modular based multi-room system using standard Cat-5/5e or Cat-6 cable to distribute hi-fi quality sound and video around a home.
BK10 Table-top keypad CONFIGURATIONS The BK10 can be used in two types of configurations: 1. As an A-BUS Ready / Incognito Ready keypad attached directly to the back of an amplifier / receiver. 2. In a full A-BUS or Incognito Multi-Room system attached to a hub. A-BUS Ready / Incognito Ready allows one or two keypads (and a PSU) to be simply connected to a hi-fi unit to allow a simple 2/3 zone multi-room system to be constructed.
A-BUS READY / INCOGNITO READY In this configuration the keypad is connected directly to the amplifier/receiver. A power supply unit (Incognito PS5) is also required to power the one or two keypads. Refer to the diagrams for system connection details: Speaker cable Speaker cable LR10 BK10 BK10 Cat5/5e cable PS5 CAP5 Multi-Room azur 640A Integrated Amplifier V2.
BK10 Table-top keypad Speaker cable Cat5/5e cable The BK10 comes with 10 metres of Cat5 connection cable, but an Incognito CP20 cable pack (with 20 metres of cable, 2 x 3.5-3.5 connection cables and a punch-down/wire stripper tool) can be purchased separately. 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.
FULL INCOGNITO SYSTEM The BK10 keypad can also be used as part of a full Incognito system, where it is plugged into an Incognito hub (AH10), perhaps with other Incognito accessories such as a video switching unit (VH10) or local input module (LM10) fitted. See the diagram below for an example of an Incognito system.
BK10 Table-top keypad Note: When using a BK10 keypad with an AH10 hub, an Incognito PS10 power supply unit MUST be used. Please consult the AH10 Incognito Multi-Room Installation Guide for full details of the various options available for the full Incognito system. IMPORTANT! The BK10 is default set to the A-BUS Ready/Incognito Ready configuration. For use in a full Incognito system, the mode switch (located inside the keypad block) must be set to the alternative “AH10” mode.
INSTALLATION NOTES Avoid placing the keypad where there is line of sight to another keypad. In such situations both keypads may pick up the same commands from a remote control and it will be difficult to control each zone independently. Avoid placing the BK10 where there is line of sight to the source equipment for the system. In such situations the source equipment may pick up the same IR commands directly as are picked up by the keypad and sent to the source equipment.
