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.

The BK10 is an A-BUS TM compatible amplified keypad unit with buttons for control of speaker volume levels, Standby/On and source select (with compatible Cambridge Audio equipment), as well as having an IR window for both receiving remote control signals and passing them to connected source equipment (IR pass-through). The BK10 can connect to the Incognito Ready outputs of Cambridge Audio receivers and amplifiers, or A-BUS hubs and A-BUS

Ready receivers from other manufacturers, using Cat-5 wiring. The BK10 then connects to speakers using conventional speaker cable.

Thanks for taking the time to read this manual, we do recommend you keep it for future reference.

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.

Alternatively when a dedicated A-BUS hub is used the system has many more options available such as sub-zones, local inputs and video switching.

Please see www.cambridge-audio.com for more details.

For both possibilities, as the BK10 is compatible with the A-BUS TM standard, the unit works with any manufacturers A-BUS compatible products, however source selection from the keypad is only possible with Cambridge Audio’s own

Incognito A-BUS system or Incognito Ready outputs on Cambridge Audio hi-fi units.

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:

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. 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 Incognito LR10 Learning Remote can fully control the keypads, “learn” the source's remote controls and change source input on the amplifier etc.

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.

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.

Use a screw driver to carefully remove the backplate and set the mode switch to the "AH10" position as shown below:

Note: Setting the mode switch to the wrong setting can cause erroneous operation!

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. This can interfere with the remote operation of the source equipment.

Do not place the keypad in areas directly lit by strong sunlight or where it will be strongly lit by fluorescent tubes. These can be sources of infra-red energy which can interfere with the remote control operation of the system. Some plasma televisions can radiate a lot of infra-red energy and care should be taken if fitting a BK10 near a plasma screen television. Avoid placing the BK10 near to dimmer switches or other items, which generate a lot of electrical noise.

Safety precautions

The BK10 runs on 24 V DC supplied through the connecting cable. As such there is no mains voltage present in the BK10 and the unit is often safe to place in areas where only extra low voltage (ELV) equipment is permitted.

However, it is imperative that you always check the wiring regulations in force for your application and area.

REMOTE CONTROL

The BK10 can be used with the Incognito LR10 remote control, a sophisticated learning remote which is able to learn the codes of all the source equipment remotes. Once programmed the user can thus use the LR10 to perform all operations from one remote.

The LR10 is also suitable where the BK10 is to be connected to the A-BUS Ready outputs of AV receivers and amplifiers instead of one of our hubs as it can learn the relevant source change commands etc of the receiver or amplifier as well as the source equipment.

Please refer to the Incognito LR10 manual for further information.
