AS10 A-BUS Active ceiling speakers
Thank you for purchasing these Cambridge Audio Incognito AS10
A-BUSTM Active Ceiling Speakers. 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. The AS10
over-paintable ceiling-mounted active speakers have amplifiers and
IR sensors built-in, and so do not require an Incognito KP10 keypad
to work. These neat components are the only visual clues to an
Incognito equipped room.
The AS10 is based on the A-BUS standard and can be used with other
manufacturers equipment based on this standard. Note that different
modes of operation are possible and it is very important that the
instructions within this guide are read and followed or the unit may not
operate correctly.
About this unit
The AS10 pair is made up of one speaker with the amplifier attached
(active AS10-A) and one conventional (passive AS10-P) speaker. The AS10
is A-BUS compatible for use where an installer wishes to avoid the
complication of a separate keypad and speakers. The drive unit and
crossover have been designed to take account of the angles,
frequencies and energy distribution characteristics of in-wall and in-ceiling
applications.
The discreet visual design of this product ensures that it is the quality of
the audio performance rather than their appearance that holds the
attention. Where required, grilles may also be painted to co-ordinate with
existing décor, rendering them virtually invisible.
Please take time to read this guide, as it contains important installation
information. The AS10 can only be as good as the system it is connected
to. Please do not compromise on your audio/visual source components.
Naturally, we recommend products from the Cambridge Audio Azur range.
Now we invite you to sit back, relax and enjoy!

INTRODUCTION

4 Incognito active ceiling speakers
It is advisable to plan all aspects of installation in advance of work
beginning, preferably with the house/flat building schematics if available.
Great care should be taken to ensure that all building regulations are
followed. If in doubt consult an expert.
When placing the AS10 speakers, thought should be given to positions
which give the best desired sound coverage throughout a room, while
not interfering with existing or planned light fittings or joists. Also, locate
speakers taking into account location of furnishings for optimal stereo
reproduction.
Follow these steps to prepare the mounting location:
1. Remove the round cardboard pad from inside the supplied template
(see below).
PREPARING THE LOCATION
Use an L-shaped probe
to check available void
space before cutting
loudspeaker holes
3. Cut the mounting hole with a drywall or keyhole saw.
Be sure the mounting surface is between 10 and 30mm thick, and
that there is at least 80mm of clearance behind the mounting
surface. Also, be sure no wall studs or other objects block the back
of the speaker.
2. Use the template to mark the position for the mounting hole at the
selected location.
Before cutting ceiling speaker holes, it is suggested that the area is
tested for clearance by making an L-shaped probe from strong wire
(see illustration below), drilling a small hole in the target area,
inserting the probe and slowly turning. Any obstructions will be
immediately obvious, and the target area can be moved to a more
suitable position.

Before mounting, ensure that the four fixing screws are slackened off so
that the red mounting dog-legs can move freely.
Move each red dog-leg foot to the LEFT into it’s holding slot, and then
insert the speaker into the mounting hole.
Using a cross-head screwdriver, slowly turn each fixing screw clockwise,
this will move the mounting dog-legs out of their slots.
Tighten each fixing screw until the mounting dog-legs grip the ceiling.
PAINTING THE FRAME AND GRILLE
Remove grille by inserting a small hook or similar small implement into
one of the grille openings, then pulling on the grille.
For AS10-A, carefully disconnect the IR connector lead before proceeding
(see fig.1 below).
Fit the clear plastic painting mask provided when painting the speaker
surround to avoid getting paint getting on the speaker cone.
For AS10-A unscrew IR window assembly before spray painting (see
fig. 2 below).
MOUNTING THE AS10
Your speakers are an example of superior design and craftsmanship.
These suggestions will help you care for them so you can enjoy them for
years.
Keep the speakers dry. If they get wet dry immediately. Liquids can
contain minerals that can corrode electronic components.
Keep the speakers away from dust or dirt, which can cause premature
wear of parts.
Wipe the speaker frame occasionally with a damp cloth to keep it
looking new. Do not use harsh chemicals, cleaning solvents or strong
detergents.

1. Using a single Cat-5e cable, connect the AS10-A to the AH10/VH10
via an RJ45 plug at the AH10, and the 8-way colour-coded punch-
down connection at the AS10-A (see wiring guide below opposite).
The RJ45 hub connection should be wired to EIA/TIA568A standard
(see below opposite).
The Cat-5 connection from AH10 to the AS10-A should not exceed
30m /100 ft.
2. The AS10-A is then connected to the AS10-P using either a run of
high-quality speaker cable (preferred) or Cat-5e cable (optional)
terminated at 8-way colour-coded punch down connections (all eight
cores must be connected).
Only one method of connection between the active and passive
speaker is necessary.
Do not compromise the performance of your system by using inferior
quality speaker cables. We recommend that high quality cables of 16
gauge or higher be used. Your professional dealer will give you good
advice. Always unplug all A.C. powered components before making any
loudpeaker or component connections. This will avoid the risk of electric
shock or damage to your equipment.
Separate about 100mm of speaker cable at each end, then using a wire
stripper, remove about 10mm of insulation from both ends of the
conductor, and then twist the strands (see fig.1 above opposite).
When connecting the AS10-A to the AS10-P, observing polarity is of the
utmost importance. Ensure that the red (+) terminals on your active
speaker are connected to the red (+) terminals on the passive speaker,
CONNECTING THE AS10
and black (-) terminals on your active speaker to black (-) terminals on
your passive speaker (fig.2 below).
The speaker cable is coded with a bead or stripe down one lead’s insulation,
or has differently coloured wires. Press the spring-loaded red or black tab to
reveal the connecting hole. Insert the stripped end of the speaker wire, then
release the tab. If your speakers are wired incorrectly they will be out of
phase and sound hollow and indistinct, with a weak bass. Re-check your
connections for correct polarity and reverse the connections if necessary.

Local Source Input
It is possible to install a piece of source equipment to be used local
to the room that contains the AS10. This might be a games machine
or CD player in the bedroom, for example. There are two ways of
connecting a local source:
INCOGNITO LM10 WALLPLATE
The LM10 wallplate has a line input and and IR output socket for IR
control of the local source via the AH10/VH10.
See dedicated literature for installation instructions.
Local Jumper MUST be set to left and centre pins – see page 11.
AS10 ONBOARD LOCAL INPUT
A local source can be connected directly to the AS10. IR control of
the source can only be done ‘line-of-sight’ in this case as the AS10
does not have an IR output.
Connection to the local input socket on the AS10-A should be via
screened audio cable, terminated at a suitable faceplate.
Local jumper MUST be set to centre and right pins – see page 11.
Preamp Output
A preamp output is provided for optional driving of an auxiliary stereo
amplifier or active subwoofer etc. Connection from the preamp should
be by screened audio cable.
ADVANCED FEATURES
If utilising the preamp output facility you may wish to activate the
Fader function. This will allow you to balance the relative output
levels between the AS10 and the auxiliary component. Move the
Fader jumper switch on the AS10-A to the centre and right pins (see
page 11).
Independent 24 V local power supply
The AS10 is powered directly from the AH10/VH10 via the Cat-5
cable. If your installation has very long cable runs from the
AH10/VH10 to the AS10 (greater than 30m) the AS10 must be
locally powered instead. This simply involves plugging an Incognito
PS10 power supply into the local power socket on the AS10.
IR Window
Receives signals from remote controls.
Blinks red to indicate signal received.
Status LED
Speaker on: Solid green.
Speaker off: Off.
Speaker in mute: Blinks slowly green.
Adjusting volume or sound: Blinks orange.
