VCR/Tape recording
If VCRs/Tape recorders are connected to one of the analogue inputs,
recordings may also be made from the AV8 VCR/Tape Out sockets.
Connect a suitable phono interconnect from the Tape Output sockets of
the AV8 to the Record inputs of the VCR/Tape Recorder.
NOTE: The Tape output sockets are active for Stereo mode only (not for
Stereo + Sub or any Surround mode).
Connecting Power amplifiers
External power amplifiers are necessary to drive the system speakers.
Both stereo and high power monoblock Cyrus power amplifiers are
available to partner the AV8.
With suitable phono interconnects, connect from the Front 1), Surround
1!, and Centre channel 1@ outputs to the appropriate power amplifiers.
The system loudspeakers may then be connected to each power
amplifier.
NOTE:- Take care to connect each of the AV8 output channels to the
correct power amplifier and loudspeaker.
In normal use, only one of the Centre channel outputs and a single
amplifier channel are connected to the Centre channel speaker.

Connecting a Subwoofer
A subwoofer may be connected with a suitable phono interconnect to
either of the Subwoofer outputs 1#. Twin outputs are provided for systems
which include subwoofers with stereo input connections or for twin
subwoofers.
Video Connections
For audio-visual sources (TV, Video recorder, DVD etc.) a separate video
connection must be made from each source to a video line input of the
TV. Some TVs will offer a choice of video connections. In most systems
the S-Video connection will give the best results (where available).
NOTE:- No video connections are made to the AV8.
MC-BUS Connections
Connecting the MC-Bus sockets 1& of the AV8 in an MC Bus system
provides unified system power control. An MC Bus loop is established by
connecting single phono cables from the MC Bus output of one unit to the
MC Bus input of another. Complete the loop by returning the MC Bus
output of the final component to the MC Bus input of the first. The
drawing below shows an example of MC-Bus wiring for a Cyrus AV8 with
a CD player and two power amplifiers.
With MC-BUS established the power function of all connected Cyrus
components may be controlled from the AV8 front panel or remote
control. When power is switched on, components such as power
amplifiers will switch on automatically.
When a Cyrus stereo integrated amplifier or pre-amplifier is connected
into the MC-BUS loop, setting of the volume calibration level will take
place automatically when the VI/AV input is selected at the Cyrus stereo
amplifier.

SETTING UP THE
The AV8 is a highly versatile product which can be easily configured to
match accurately the requirements of different Home-Theatre systems.
The recommended initial setting up procedure for the AV8 is this-
•
Set speaker sizes
•
Set input names
•
Set the channel balance and positions for the speakers
•
Set special modes of operation
Setting up takes place from the remote control using the SET-UP key
area 3&.
You can return to normal operation from the set-up sequence at any time
by pressing the EXIT key 3% on the remote control.
AV8
Setting speaker sizes
The first step in setting-up the AV8 is to set the sizes of each system
speaker using the following key sequence-
1. Press one of the SPEAKER HOT-KEYs 3& twice to select speaker
size setting. The display will show the chosen speaker name with
the current set size (Fig.4.1).
2. Choose the correct speaker size with the ADJUST keys 3^. The
options are SMALL (for bookshelf or satellite speakers), LARGE (for
larger stand mounting or floor-standing speakers), or NONE (if a
speaker is not connected in this position).
3. Press the next SPEAKER HOT-KEY 3& to save this setting and
move on to set the size of the next speaker, and finally the
subwoofer.
The speaker symbols on the display change shape to show the selected
sizes for the system speakers (Fig 4.1 shows large front speakers with
small centre and surround channel speakers).
NOTE:- If SMALL size is selected for all of the system loudspeakers, a
subwoofer must be connected and selected to enable the bass
frequencies to be correctly reproduced.
CAUTION:- For the correct reproduction of DTS encoded recordings
large speakers are recommended for all sound channels. Speaker size
settings are therefore disabled when the AV8 is decoding DTS encoded
recordings. If DTS encoded recordings are played through small system
speakers caution should be exercised to avoid possible damage through
bass overload.
Setting input names
When the AV8 leaves the factory, the input names are set to correspond
to the rear panel connections, for example Input 1 will display as- Input 1,
IN-1 Digital.
The name of any input may be changed to a choice from the following
list-
•
LaserDisc, DVD, DVD 1, DVD 2, DVD-A, CD, CD 1, CD 2, SACD,
CD-R, Jukebox
•
Phono, Deck, Vinyl
•
Tuner, Radio, DAB
•
TV, Satellite, Satellite 1, Satellite 2, Cable
•
Video, VCR, VCR 1, VCR 2, Tape, Cassette, MD, MiniDisc, DAT
•
PC, Games, Special, Keyboard, Aux
To change the names of the inputs, first make a list of each input number
with your preferred name from the choices above. Where an input is not
used, make a note- unused inputs can be switched off.
To rename the current selected input follow this sequence-
Press the SET-UP 1 ‘INPUT’ key 3* on the remote control. The
1.
display will now show the selected input number on the top row and
the current name on the bottom row with brackets (Fig.4.2).

Now you can choose to exit and save the changes (press the EXIT
3.
key 3%) or to re-name another input (repeat step 1 to select another
input then step 2 to re-name it).
Setting speaker channel balance and positions
To ensure the best performance from your multi-channel audio system it
is essential to balance all sound channels to reproduce equal sound
levels from the system speakers. The AV8 includes two noise set-up
options-
•
Manual noise adjustment to balance individual speaker volume
levels.
•
Fully automatic adjustment to balance speaker volume levels and to
measure the distance to the speakers.
The automatic system is recommended, particularly for initial adjustment
to get the system running.
NOTE:- To allow high volume levels to be reached, high value positive
balance settings are reduced at very high settings of the volume control.
When this condition occurs, the display will flash the legend ‘Balance
limiting’ briefly. Normal balance settings are restored when the volume
setting is reduced.
Manual noise adjustment
Press the SET-UP 2 NOISE key 4) once to start the manual noise
sequence. MANUAL CAL will now show on the display and a 5 second
count down begins (Fig 4.3). After the count down a noise signal will be
heard from the front left speaker. Set the noise to a comfortable level with
the ADJUST keys 3^. The noise will now cycle around all of the system
speakers.
As the noise sequence moves you can compare the sound level from
each speaker and make level balance adjustments with the set up
ADJUST keys 3^. The display shows the active speaker and a bargraph
for balance level (Fig 4.5). If no adjustment is made within 2 seconds the
noise will sequence to the next speaker in the system. When adjustment
is complete, press the EXIT key 3%.
When noise adjustment is active the top row of the display will show the
selected speaker while the bottom row indicates the current balance
setting from –10dB to +10dB (Fig 4.5).
Manual distance setting
Before commencing manual distance setting, measure the distance from
each of the five main channel speakers to the listening position and make
a note of the measurements.
1. Press one of the SPEAKER HOT-KEYs 3& three times to select
speaker distance setting. The display will show the chosen speaker
name with the current set distance (Fig.4.6).
2. Choose a distance measurement for the chosen speaker from the
available options with the ADJUST keys 3^. Distances can be set in
the range 0-9.1m (30ft).
Press the next SPEAKER HOT-KEY to save this setting and move
3.
on to set the distance to the next speaker.
Automatic level adjustment and distance setting
NOTE- For automatic setting the microphone must be connected to the
rear panel socket 1* before starting the process. The battery must be
fitted inside the microphone plug before use. Observe the polarity
markings when fitting the battery. Remove the battery from the
microphone if it is only used occasionally.
Before commencing the sequence, set up the microphone in the
1.
listening position at approximately head height, facing vertically
upwards.
Press the SET-UP 2 NOISE key 4) twice to start the automatic
2.
noise sequence. AUTO CAL will show on the display with a 5
second count down (Fig 4.7). Before commencing the AUTO CAL
sequence the AV8 will perform a microphone test with a short noise
burst. If there is a problem with the microphone or it’s connection,
the display will show a ‘Mic Error’ indication. In this case the
microphone connection and battery should be checked before restarting the AUTO CAL process.
Following a successful microphone test the noise signal will be
3.
heard at an increasing level from the front left speaker and the set-
up sequence will start.
The set-up sequence runs in two parts, the first will set the relative
volume levels between the loudspeakers, the second will measure the
distance from the listener to the speakers and set corresponding delay
times. At the end of the sequence the display will show ‘Complete’ (Fig.
4.8) for 5 seconds before returning to normal operation. The stored
settings can be checked, if required by selecting Manual Noise or
Distance adjustment.
Factory balance settings
The factory setting for all channels is centre scale when all channels are
at equal volume.
NOTE:- The noise sequence is also helpful to check that all channels
have been connected correctly. When correctly connected the noise
should start with the left front channel and circulate clockwise.
Setting up the sub-woofer
For correct reproduction of the deep bass content of multi-channel hometheatre programs a sub-woofer is recommended for AV8 systems.
Deep bass information is fed to the sub-woofer in two ways-
From the separate LFE low frequency effects channel of digitally
1.
encoded programs.
When one or more of the system speakers are set to ‘small size’ the
2.
bass from these speakers will be re-directed to the sub-woofer.
Sub-woofer level
The overall level of sound from the sub-woofer can be adjusted at any
time by selecting SUB/LFE from the SPEAKER HOT-KEYs 3& and using
the ADJUST keys 3^ to increase or reduce the level from the sub-woofer
(Fig. 4.9). Most sub-woofers will also have a control panel which includes
level adjustment. The recommended procedure for setting the two
controls is as follows-
Set the AV8 sub-woofer level adjustment to 0dB (centre scale).
1.
Play a program which includes sub-bass content and adjust the
2.
sub-woofer level control to your preferred level.
A full ±10dB range is now available from this nominal setting via the AV8
remote control when listening.
Sub-woofer mode
The sub-woofer can be switched on or off at any time (for example, when
listening late at night) by pressing the SUB/LFE key from the SPEAKER
HOT-KEYs 3& twice and using the ADJUST keys 3^ to select ON or OFF
from the display (Fig. 4.10).
Sub-woofer crossover
The factory setting for the crossover frequency between small system
speakers and the sub-woofer is 100Hz which should be adequate for
most systems. If required, however the crossover frequency may be
changed to better match the low-frequency 3dB response specification of
‘small’ system speakers. The procedure for re-setting the crossover
frequency is as follows-
Press the SUB/LFE key from the SPEAKER HOT-KEYs 3& three
1.
times. The display will show ‘SUB X-OVER’ and the frequency
currently set.
To change this frequency in the range 50Hz-150Hz, use the
2.
ADJUST keys 3^.
Note:- If all system speakers are set to ‘large’, the sub-woofer crossover
frequency will have no effect.

3.
Note:- When a sub-woofer is not selected the LFE channel information
will be routed to any ‘large’ system speakers to avoid information loss.
Dynamic compression
Two dynamic compression settings are provided to reduce the dynamic
range of the system. When dynamic compression is selected, louder
passages will be reduced in volume slightly whilst quieter passages will
be increased slightly. The degree of this effect is greatest with the ‘HIGH’
setting. This feature is useful with speaker systems of reduced capacity
or for late-night listening. Some experimentation is recommended to find
the best setting.
Dynamic Compression selections may be made as follows-
Press the MODE key 3( until the display shows ‘Dyn. Compression’
1.
and the current setting (Fig 4.13).
To change the setting between OFF, LOW and HIGH, use the

NOTE:- Centre width, Dimension and Panorama settings may not be
changed when set to Movie mode, ‘Music only’ will be displayed if these
menu options are selected.
Stereo
If a two-channel signal is detected the AV8 will automatically select Dolby
Pro Logic II decoding. If stereo reproduction is required (for CD music
etc) the STEREO key 3! of the remote control will switch between Pro
Logic II surround and Stereo decoding. An additional Stereo + Sub mode
is available via a second press of the STEREO key 3! which activates
Stereo decoding with bass reinforcement from the subwoofer (when
connected).
Press the STEREO key 3! again to return to surround decoding.
NOTE:- When purchasing program discs or tapes, check the legends on
the sleeve to ensure compatibility with the listed systems.
NOTE:- Some discs (e.g. DVD) may provide a selection of audio
encoding systems or a choice of languages. In this case the correct
system/language is selected from the control menu of the DVD player.
NOTE:- The AV8 employs an ‘auto-mute’ feature for DTS encoded
program material. If the DTS signal is interrupted (e.g. during fast search
or when changing discs) the display will read ‘AUTO-MUTE’ (Fig 4.16)
until the signal is restored. When changing from DTS programs to stereo,
it is necessary to re-set the auto-mute function with the MUTE key 3).
Level Control
The volume level is adjusted by the rotary LEVEL control on the front
panel 2^ or the LEVEL keys on the remote control 3$. When the volume is
adjusted the main display will switch briefly to show the setting in dBs
(Fig.4.15). Additionally, the display bargraph 2# shows the volume level at
all times.
Adjusting channel balance and Subwoofer level
The channel balance settings may be adjusted at any time from the
remote control with the SPEAKER HOT-KEYs 3&. Choose a speaker to
adjust with one of the keys then correct the channel balance with the
ADJUST keys 3^. The bottom row of the display will show the channel
balance setting in the range –10dB to +10dB (Fig. 4.5 shows centre
channel adjusted up by 2dB).
The Subwoofer level can be adjusted in the same way after first selecting
SUB/LFE from the SPEAKER HOT-KEYs 3&.
