INSTALLING AN AV SYSTEM
The AV master is a versatile six-channel Home Theatre
decoder unit which can be installed in two ways. Installation
and operation instructions are given for both options. The
options are-
'System 1', where a separate integrated amplifier (or a
pre/power combination) is also installed in the system. The
audio sources are connected to the system amplifier, whilst the
audio visual sources are connected to the AV master. The audio
will operate independently of the AV master whilst the AV
master will fully control the audio visual sources. (You will
need an additional Cyrus Power amplifier to ensure full
functionality of front and rear channels.).
'System 2', where the AV master is installed with power
amplifiers for the front and rear channels. In this way, as many
as four input sources may be connected to the AV master and
all input selection and volume control adjustments take place
through the AV master.
NOTE:- Certain connections and operating procedures apply
only to a 'System 1' set-up. These sections are highlighted as in
this example.
System 2 owners should skip these sections.
Examples of both systems are shown on the next page. Interwiring between the Cyrus amplification components are shown
as bold lines.

INSTALLATION Cyrus AV master
POSITIONING THE SYSTEM COMPONENTS
Location of the TV monitor in a Home Theatre system
The TV in a Cyrus Home Theatre system should ideally be
located centrally at the front of the chosen viewing area. The
monitor location should allow correct positioning of the left
and right loudspeakers.
Positioning the loudspeakers
The main left and right loudspeakers should be placed on each
side of the TV monitor, equi-distant from the viewer. If
domestic conditions restrict the placement of the speakers, the
ALS (auto-alignment system) of the AV master may be used to
compensate for any inaccuracies in volume level which result.
Set up the front speakers for best stereo results in accordance
with the manufacturer's instructions.
Surround channel speakers should be positioned behind the
listener on the side walls or rear wall. The loudspeakers should
ideally be mounted high enough to avoid acoustic masking by
furniture. Good results and minimum visual impact can often
be achieved by mounting the loudspeakers at ceiling height.
The centre channel dialogue speaker should be located
centrally, above or below the TV monitor to link the centre
channel sound closely to the on-screen action.

Cyrus AV master INSTALLATION
CONNECTION
Before proceeding to connect the AV master, ensure that all
system components are disconnected from the mains power
supply.
For a system 1 installation: Please ensure that the main system
amplifier and source components have been installed and fully
tested before connecting the AV master and the audio visual
sources to the system.
Installation cautions
• All stereo audio signals must be correctly connected for left
and right channel alignment. Stereo RCA phono
interconnects are colour coded to assist with channel
identification.
• All speaker connections must be checked to ensure phase
polarity. The + or red speaker terminal must always connect
to the + or red amplifier terminal. Speaker cables are
marked with a moulded or coloured tracer to enable channel
identification.
• The AV master is not designed for connection to video
signals. Permanent damage may result if video connections
are made to the audio inputs.
The numbers in the text of the following section refer to the
rear panel view on page 10
AUDIO CONNECTIONS
Connecting inputs to the
AV master
Up to four inputs may be connected to the AV master audio line
inputs AV1-AV4
- . These could be from audio visual
program sources such as a TV monitor audio output, VCR,
video disc player or a home video camcorder or from stereo
audio sources such as a CD player, FM tuner or cassette deck.
For each input, connect a stereo RCA phono interconnect from
the audio output connections of the source to the chosen rear
panel input sockets AV1-AV4
- .
Connecting a VCR or cassette deck for audio recording
Record output connections are also available for a VCR or
stereo cassette deck. Connect a RCA phono interconnect from
the AV master REC OUT sockets
to the line audio inputs of
the VCR or cassette deck.
VIDEO CONNECTIONS
The audio outputs of your video recorder, laser disc player, etc
should be connected to the Cyrus AV master line inputs. Video
outputs should be connected to the TV monitor (or video
processor if you have one). Please consult the user manuals of
your TV and video components for details.

INSTALLATION Cyrus AV master
CONNECTING THE FRONT CHANNEL MAIN
AMPLIFIER
For System 1, front channel amplification is provided by a
stereo integrated or pre/power amplifier at the centre of an
existing audio system. In this case, connect the video input
sockets of this amplifier to the FRONT sockets of the AV
master.
NOTE:- When connecting to a Cyrus stereo system the video
input of the amplifier must be used to achieve the correct level
calibration settings. For other amplifiers which may not have a
specific video input any line input will be suitable.
For System 2, front channel amplification is provided by a
stereo power amplifier. Connect a stereo phono interconnect
from the FRONT sockets
of the AV master to the
corresponding inputs of the front channel power amplifier.
CONNECTING THE REAR CHANNEL SURROUND
AMPLIFIER
A stereo power amplifier can now be connected for the rear
surround channels. Connect a stereo phono interconnect from
the REAR sockets
of the AV master to the signal inputs of
the surround channel power amplifier.
LOUDSPEAKER CONNECTION
Position the loudspeakers for the front and surround channels
and cut the speaker cables to length allowing some for cable
dressing. Connect the speaker cables to the front and surround
amplifiers and speakers. Refer to the instructions and cautions
in the amplifier handbooks.
Centre channel loudspeaker
Position the centre channel dialogue loudspeaker either above
or below the TV monitor. Prepare a suitable cable and connect
the speaker to the AV master CENTRE sockets
.
The system speaker connections are now complete. Re-check
each speaker cable connection for the correct channel and
phase polarity. An incorrect connection will compromise the
sonic performance of the system.
If you are using high performance amplifiers to drive the front
speakers, you may wish to add a monoblock to the centre
channel. A special line adaptor is available to convert both the
impedance and signal level from the centre channel output of
the AV master to the line level needed for monoblock
operation. Connected in this way, the centre channel will
function as a high quality preamplifier, enabling you to
optimise the AV master’s centre channel performance.
For details of this impedance convertor, please consult your
Cyrus dealer.

Cyrus AV master INSTALLATION
SUBWOOFER CONNECTION
Subwoofer selection
A subwoofer may be added to the system to enhance deep bass
performance. When selecting a subwoofer, an 'active' design
(with internal amplifier) is preferred as the AV master can
provide full remote control of active subwoofer level. Passive
subwoofers must be connected to the front system speakers and
cannot be independently controlled in this way.
Active Subwoofer connection
Subwoofers may have single or dual input connections.
For single input subwoofers, use a single RCA phono
interconnect and connect from the line input of the subwoofer
to the top SUB OUT socket
of the AV master. For stereo or
dual input subwoofers, use a stereo RCA phono interconnect
from the line inputs of the subwoofer to both SUB OUT
sockets
PSX-R
of the AV master.
CONNECTION
If a PSX-R is to be used with the AV master, connect the
umbilical cord of the PSX-R to the 5-pin PSX-R INPUT socket
of the AV master. When correctly fitted, the connector will
latch into place in the socket. Note that when a PSX-R is in use,
both the PSX-R and the AV master will require mains power.
Where the AV master is used in conjunction with an existing
stereo audio system, the operation of the stereo amplifier and
its connected input sources remains completely separate from
the audio visual inputs and extra sound channels provided by
the AV-master. The AV master should therefore remain set to
standby unless an audio visual source is to be selected. (If
you own other Cyrus components, you can extend this
functionality - please refer to Page 21 for details )
POWER CONTROL
The mains power switch is located at the rear of the unit. This
switch should be left on for normal operation, except when the
unit is left unattended for long periods. In this case the mains
power should be switched off or the product disconnected from
the mains power supply.
The numbers in the following text refer to the front panel
drawing on page 10.
When the AV master is in regular use and the power is on, the
STANDBY key
STANDBY light
can be used for power control. The
will indicate red when the unit is off (in
standby mode) and green when operational. Remember also to
switch on the system amplifiers when the AV master is in use.
Cyrus components can operate automatically if required (see P.
21.)

Cyrus AV master OPERATION
Careful setup of an A/V system is critical if the system is to
work properly. Please read the following sections thoroughly
and carry out the operations indicated in the proper sequence.
SETTING THE REFERENCE LEVEL
For owners of a 'System 1' set-up (see pages 4 & 5) where
front channel amplification is provided by a stereo integrated
amplifier or Pre/Power amplifier combination, it is essential to
set the volume control of this amplifier to a known reference
level when used with the AV master as follows-
With some Cyrus amplifiers, including Cyrus Pre, Cyrus III,
this setting can easily be achieved. The following procedure
should be followed each time the system is used-
• Adjust the volume level slowly until
the volume display matches the diagram.
When correctly set the volume displays one
green light in the indicated position (two
o’clock). The amplifier reference level is now
accurately set.
With other amplifiers the volume control should be set at that
point where the noise burst levels are of equal loudness when
the AV master is in manual calibration mode. (Refer to P. 12
for details)
CAUTION:- Remember to reduce the volume setting before
switching the main amplifier to another input source.
CALIBRATING THE SYSTEM- SPEAKER LEVEL
Accurate speaker level calibration is critical in a Home Theatre
system to project the most realistic sound image.
The MISSION auto-alignment system
ALS
provides a fast and
accurate automatic level setting system. An essential
requirement is the miniature microphone (supplied) which
connects to the AUTO LEVEL MIC socket
on the AV
master rear panel. Before connecting the microphone to the
socket the battery must be fitted. Unscrewing the barrel from
the microphone plug case will expose the battery holder. Fit the
battery into the holder observing polarity and re-fit the barrel to
the plug. The microphone can now be plugged in.
NOTE:- If the ALS system is not in regular use, disconnect the
microphone and remove the battery.
ALS calibration is only necessary when initially setting up the
system, when moving to a new listening position or when
changing any of the system loudspeakers. The AV master will
memorise ALS settings each time the STANDBY key
is
operated or when storing settings in the memory.
Although the ALS system is the most accurate and efficient
way to calibrate the system loudspeakers, a manual alignment
option is available. The following page gives details of both
methods.

KNOW YOUR
AV MASTER
Power
• When first switched on from the power switch on the rear
panel, the AV master will run a self test, checking the
internal functions and the LCD display operation. After
completion of this cycle the AV master will revert to
standby mode.
• When set to standby, all current settings are normally
retained. If, however, the unit is put in standby mode whilst
set to abnormally high volume settings, when next switched
on the AV master will power on at a master volume level of
-15dB .
The
For owners of the Cyrus System Commander, the following
information may be of some use:
When the Cyrus System Commander is used to control the AV
master it is possible to select the four input sources.
This is achieved as follows:
Using the function key, select 'green' a/v mode. By pressing the
Tape (TP) key, you can then scroll through the input sources
till you reach the desired one.
Turning the AV master on via the Commander is also
accomplished by pressing the TP key in 'green' mode.
Stereo bypass
• In standby, the Centre channel power amplifier is shut down
to minimise power consumption and heat generation.
Addition of a
• The addition of a Cyrus PSX-R- a highly regulated DC
PSX-R
power supply, will upgrade the sonic performance of all
sound channels of your AV master by providing a clean,
stable power feed for the sensitive multi-channel decoder
stages. No adjustments are necessary when connecting the
Cyrus PSX-R to the AV master- refer to page 9 for
connection instructions.

When the AV-master is set for Stereo sound mode the internal
decoder is completely by-passed to ensure the most direct link
for stereo signals which require no processing.

The
MC-Bus System
The AV master also supports connection for the Cyrus MCBus. The MC-Bus system enhances functionality and ease of
use by harmoniously linking together the intelligent control
systems of many Cyrus components.

Cyrus AV master ADDITIONAL INFORMATION
MC-Bus System Connection-'System 1'
MC-Bus connections should be wired as a 'loop' using single
RCA interconnects. This typical 'System 1' set-up uses a Cyrus
III amplifier, DAD7 CD player, AV master and a Cyrus Power
amplifier for the rear channels. Connect a cable between the
MC-Bus output of the Cyrus III and the MC-Bus input of the
next Cyrus component. Wire the MC-Bus output of each
component to the next MC-Bus input, finally returning to the
Cyrus III input to complete the loop.
MC-Bus connections- 'System 2'
This typical 'System 2' set-up features an AV master, a Cyrus
CD player and two Cyrus Power amplifiers for the front and
rear channels. Starting with the AV master output wire the MC-
Bus loop of each component to the next MC-Bus input, finally
returning to the AV master input to complete the loop.
NOTE:- Many Cyrus products may be connected as detailed in
an MC-Bus loop.
It is possible to control the system in the following way-
• One-touch Standby control for the full system, from the
front panel or remote, of the Cyrus III, or Cyrus Pre.
• Selecting the VI input of the Cyrus III/Cyrus Pre will
switch on the AV master.
NOTE:- On some Cyrus amplifiers, selecting the VI input of
the amplifier will automatically switch on the AV master and
set the reference level. For details see the relevant manual.

It is possible to control the system in the following way-
• One-touch Standby control for the complete system from
the front panel or remote control of the AV master.
Note. Some Cyrus products are available which do not feature
MC-Bus. Products such as the XPA power amplifier feature
automatic turn-on and shut off, thus rendering them
operationally compatible with MC-Bus equipped components.

TROUBLESHOOTING Cyrus AV master
TROUBLESHOOTING
The installation of a full Home Theatre system can be complex.
If the system will not respond correctly after installation we
recommended-
• Disconnect the power from the system.
• If you are already own Cyrus components, pease read
your user manuals thoroughly.
• Check carefully all signal connections between the system
components.
• Check all loudspeaker connections at both ends of the
cables.
• Re-connect the system power and switch on all
components.
• Select the correct input for the front channel amplifier and
check the Reference Volume setting at the front channel
amplifier if necessary (see page 11)
• Run the ALS calibration system, checking that a sound is
heard from each speaker during calibration.
• When ALS calibration is complete, select an input and set
the chosen source to play.
If problems persist, refer to one of following sections for
guidance.In the event of an unresolved installation problem,
please refer to your dealer for assistance.
No sound from any speakers
• Check that the correct input is selected and the source is set
to play.
• Check that the power is switched on for all system
amplifiers and that the volume control is not at minimum.
• Check that mute is not on (the centres are removed from the
display speaker symbols when muted).
No Sound from the front channels
• Check that the front channel amplifier is switched on.
• Check that the correct input is selected at the front channel
amplifier.
• Check that the volume of the front channel amplifier is set
to the reference level (see page 11).
No Sound from the rear channels
• Check that the rear channel amplifier is switched on.
• Check that a sound mode is selected with active rear
channels.
Low volume level from the front channels
• Check that the volume of the front channel amplifier is set
to the correct reference level (see page 11).
Unbalanced sound levels from the sound channels
• Re-calibrate the loudspeaker acoustic levels with the ALS
calibration system (see page 11).

Cyrus AV master TROUBLESHOOTING & SPECIFICATIONS
Unable to complete
• Check that all system amplifiers are switched on
• Check that the ALS microphone is connected to the rear
ALS
calibration
panel and that the microphone battery is not flat.
• Check that the correct input is selected on the front channel
amplifier.
• Check that the front amplifier Reference Level is correctly
set (see page 11). If the volume control of the front channel
amplifier is set too low, ALS calibration may not be
possible.
No TV picture or the wrong TV picture
• Check that the TV monitor is set to the correct line input or
channel for the chosen source.
• If video connections are 'chained', ensure that all audio
visual sources in the chain are switched on and that the line
inputs are correctly set.
Front and Effects channels play different programmes
• It is a common problem with non-integrated A/V systems
for front and rear channels to be playing different sources.
Ensure the amplifier's input is connected to the same source
as the AV master or set the
AV master to STANDBY.
