KP10 A-BUS keypad  
INTRODUCTION  
Thank you for purchasing this Cambridge Audio Incognito product. Incognito is a cost-effective,  
modular based system using standard Cat-5 or Cat-6 cable to distribute hi-fi quality sound and  
video around a home.  
TM  
The KP10 is an in-wall, A-BUS compatible amplified keypad with buttons for control of speaker  
volume levels, Standby/On and source select (with compatible equipment), as well as having an  
IR window for receiving remote control signals. The KP10 can connect to A-BUS hubs, A-BUS  
Ready receivers, or to the Incognito Ready outputs of Cambridge Audio receivers and amplifiers  
using Cat-5 wiring. The KP10 then connects to speakers using conventional speaker cable.  
The KP10 keypad fits into any wall and is available with different finishes to compliment various  
decorative schemes. The KP10 is fitted on the wall by fixing it into a standard single UK 47mm  
electrician’s back-box. All knock-outs in the back-box should be removed to provide maximum  
ventilation. Care should be taken in choosing a site for the KP10, and always refer to the  
precautions in this guide. Bear in mind it is not always preferable to fit the KP10 next to a light  
switch, particularly if the faceplates will differ.  
Thanks for taking the time to read this manual, we do recommend you keep it for future  
reference.

SYSTEM OPTIONS  
The KP10 keypad can be used in two main configurations:  
1. 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.  
2. Where the keypad is plugged directly into an A-BUS Ready/Incognito Ready output of a  
compatible Cambridge Audio (or other brand) A/V Receiver or Amplifier, no other accessories  
are possible other than the required power supply and remote control/s.  
The KP10 has two modes of operation to support these configurations, AH10 mode and  
Standard A-BUS/Incognito Ready mode. The modes are selected by setting the Mode switch,  
located on the rear of the KP10.  
Note: Setting the Mode switch to the wrong setting can cause erroneous operation!  
Full Incognito system  
For use in a full Incognito system (see diagram opposite) the Mode Switch MUST be in the "AH10"  
position as shown below:

In this configuration the keypad is wired directly to the amplifier/receiver. A Power Supply Unit  
(PS10) is also required to power the one or two keypads as shown.  
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.

INSTALLATION NOTES  
The KP10 is fitted on the wall by fixing it into a standard UK 47mm depth single-gang  
electrician’s back-box (pattress). All knock-outs in the back-box should be removed to provide  
maximum ventilation.  
Where it is desired to fit a mains lighting switch etc next to a keypad, a barrier-box or two single  
back-boxes must be used (bear in mind it is not preferable to fit the keypad next to a light-switch  
particularly if the faceplate styles will differ). Only a qualified electrician should attempt such  
installations.  
Avoid fitting the KP10 where there is line of sight to another KP10. 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 fitting the KP10 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 fit 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 KP10 near a plasma screen television. Avoid placing the  
KP10 near to dimmer switches or other items, which generate a lot of electrical noise.  
8 Incognito KP10  
 
KP10 A-BUS keypad  
Safety precautions  
Care should be taken when choosing the site for a KP10, the keypad must never be installed in a  
back-box which also contains mains wiring or in areas of high humidity.  
The KP10 runs on 24V DC supplied through the connecting cable. As such there is no mains  
voltage present in the KP10 and the unit is often safe to fit 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.  
Faceplates  
The KP10 faceplate system is based on the 50 x 50 ‘easy-clip’ module standard and is  
interchangeable with the wide range of faceplates made by manufacturers such as MK Electric,  
RPP etc that conform to this standard. If it is desired to fit another faceplate, it can be replaced  
by gently prising apart the KP10 faceplate and snapping on another in its place.  
Fitting the keypad  
Remove the supplied faceplate from the KP10 by gently prising apart. It will “pop” off. Connect  
each wire in the Cat-5 cable to its respective terminal in the screw-down connector on the back  
of the KP10 (refer to the Cat-5 to KP10 screw-down connectors diagram in the ‘Rear panel  
connections’ section of this guide). The recommended maximum length for use with standard  
Cat-5 cable is 30m from hub to keypad in total (screened Cat-5 cable can also be used). After  
making the wiring connections, fit the KP10 to the back-box with the two supplied M3.5x20  
screws. Gently push the faceplate back on to the module.  
Note: If in doubt about any aspect of installation or wiring, seek professional advice from a  
qualified installer.

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 KP10 will only rotate round the main 6 sources.  
REMOTE CONTROL  
The KP10 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 KP10 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.  
Note: Please refer to the Incognito LR10 manual for further  
information.
