Incognito table-top keypad 3
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-BUSTM 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:

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:
BK10 rear
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.

Connect to a pair of speakers with two
runs of standard high-quality speaker
cable. Speakers of at least 88 dB SPL
for 1W @ 1 metre efficiency should be
used with the BK10. Speakers from

and holding the Standby button for
about 2 seconds, all BK10s
connected to the AH10 hub will be
turned off. If the BK10 is connected to
a Cambridge Audio Incognito Ready
Amplifier rather than an AH10 hub,
the amplifier will be turned off.

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.

OPERATING INSTRUCTIONS
Volume adjustment
Volume is adjusted using the volume up and volume down buttons on the
keypad or remote; this is indicated on the keypad by the intensity of the blue
LED lights, there are four levels of intensity per LED.
Source selection
The Source left and right buttons allow you to choose from multiple connected
sources. The LED display will indicate which source is selected.
Sound adjustment modes
Pressing the Power/Standby button while holding the Volume down key
activates the sound adjustment modes, the four central LEDs on the keypad
will then light in sequence to indicate each of the four sound adjustment
modes in turn; Bass, Treble, Balance and Fader. These modes can also be
activated using the 'Select' button on the remote control.
After holding both buttons down for a short period, the second LED on the
keypad will light indicating that Bass adjust mode has been activated. In this
mode pressing the Volume up/down keys will adjust the Bass (low frequencies)
level.
Continuing to hold both keys down will light the third LED indicating that Treble
adjust mode has been activated. In this mode pressing the Volume up/down
keys will adjust the Treble (high frequencies) level.

up/down keys will adjust the balance between
the main speakers and the pre-amp output. The
pre-amp output is on the rear of the KP10 and not
accessible from the back of the BK10.
The volume up and down buttons on the remote
control can also be used to adjust the sound in
each mode.
Note: If no adjustment is made the system will
automatically go back to volume adjustment after
two seconds.

After holding both buttons down for a short
period, LED 2 will light indicating that Sources
1–6 (default) are available for selection.
Continuing to hold both keys down will light LED 3
indicating that Sources 1–6 + Local source 1
mode is available for selection.
Continuing to hold both buttons will light LED 4 indicating that Sources 1–6 + Local source 1 +
Local source 2 mode is available for selection.
Continuing to hold Volume up and Power buttons will light LED 5, to indicate
that Off mode is available for selection, and no source will be selected.
To select these modes, wait till the corresponding LED is lit and then release
Power and Volume up buttons.
Note: If no adjustment is made the system will automatically go back to volume
adjustment after two seconds. If “Standard A-BUS/Incognito Ready” mode is
selected on the Mode switch, the BK10 will only rotate round the main 6
sources.
