Connecting Loudspeakers
Fit plugs to the loudspeaker cables making sure to line up +
and - at each end. Most cables have polarity indicators and
may also be marked for direconality. The + and - terminals
must be connected to the corresponding + and - terminals
of the loudspeakers.
Ensure that the connecons are secure, then connect the
le and right loudspeakers to the rear panel sockets 1@ and
a.
NOTE: The dual output sockets are provided for convenient
connecon of bi-wiring speaker cables as shown.
Using the Zone 2 output of your amplier
Your product includes a Zone 2 pre-amp output that can be
used by a system in a second room. You can then extend the
sound from the sources in your main system to a second
zone. To use the Zone 2 output you will need a set of long
interconnects and an amplier with loudspeakers in the
second zone that has its own volume control. Typically the
second zone system would be the auxiliary input of an MP3
player dock or could even be another integrated amplier
with full size separate loudspeakers.
Setting up Zone 2 with powered speakers
To set up Zone 2, connect the long phono cables to the Zone
2 output e and route them to the line inputs of the powered
speakers in Zone 2.
Setting up Zone 2 with a second amplier
To set up Zone 2 with a separate amplier, connect the long
phono cables to the Zone 2 output eand route them to one
of the line inputs of the amplier in Zone 2. Connect the
Zone 2 speakers to the Zone 2 amplier.
NOTE: Ampliers for Zone 2 use must include a volume
control.
Connecting a Tape/Disc recorder for recording
When not in use for a Zone 2 system, the dual-purpose
output Zone 2/Tape may be used to connect a tape recorder
for recording purposes. To set up a tape recording loop,
connect a phono cable from the ‘Input’ or ‘Record’ sockets
of the tape deck to the Zone 2 Output e sockets.
NOTE: This secon assumes that the ‘Play’ or ‘Line Out’
sockets of the tape/disc recorder have already been
connected to Input 6 for playback purposes.

Connecting a bi-amplified speaker system
Bi-amping
The twin pre-amplier outputs may be used in conjuncon
with added power amplier(s) to signicantly upgrade your
loudspeaker system through Bi-amping. The Cyrus range of
power ampliers is recommended for this applicaon.
NOTE: A bi-amp system can only be set up with speakers
that have bi-wire connecons (separate bass and treble
connecons).
Connecting power ampliers:
An external power amplier is necessary to drive the system
speakers when bi-amping.
Both stereo and high power monobloc Cyrus power
ampliers are available to partner your amplier.
Connecting a Cyrus Surround Sound
decoder
If your system includes a Cyrus mul-channel surround
sound decoder, it may be connected through your stereo
amplier to share the main front speakers of your system.
In this case, connect a stereo phono interconnect from the
front channel outputs of the surround decoder to one of the
Analogue Inputs of the amplier. For this system to funcon
correctly both the amplier and the Cyrus surround decoder
must be included in an MC-BUS connecon loop and the
‘Cyrus AV’ input name must be set for the input used (see
‘MC-BUS’ secon and ‘Input names’ in the ‘Setup menu’
secon).
When set up in this way, the amplier will automacally
check for the presence of the decoder when the ‘Cyrus
AV’ input is selected, then lock its volume seng to an
appropriate level.
Connecting a Surround Sound decoder
(other brand)
If your system includes a mul-channel surround sound
decoder (but not a Cyrus model), it may be connected
through your amplier to drive the front channel speakers.
In this case, connect a stereo phono interconnect from the
front channel outputs of the surround decoder to one of the
Analogue Inputs of the amplier. For this system to funcon
correctly, the ‘AV Direct’ input name must be set for the
input used (see ‘Input names’ in the ‘Setup menu’ secon).
When set up in this way, the amplier will automacally lock
its volume seng to a xed level to match the output of the
surround decoder.
CAUTION: The ‘AV Direct’ input name should only be used
for surround decoders that include a volume control, as the
volume control of your amplier will be xed at a very high
level.
NOTE:- Refer to the wiring plan of a bi-amplied system.
Take care to connect each of the amplier output channels
to the correct power amplier and loudspeaker.
Connecting Headphones
The headphones socket 1( is a standard 3.5mm stereo jack
socket for connecon to a pair of headphones. Headphones
may be permanently connected to the amplier and selected
when required with the front panel switch.

MC-BUS System
Connecng the MC-BUS sockets bin an MC-BUS system
provides unied system control.
External Power Supply - PSX-R
(Cyrus 8 DAC)
The PSX-R is a unique DC power supply which will upgrade
the sonic performance of your amplier. When an amplier
/ PSX-R combinaon is installed, analogue and signal related
secons of the amplier are powered from this clean,
stable power source while other requirements are supplied
internally. This ensures complete isolaon of control circuits
and sensive analogue secons reducing AC mains-borne
noise and power supply ripple.
To connect the PSX-R to the amplier, disconnect both
components from the mains, then plug the connector on
the umbilical cord of the PSX-R into the Mul-Pole socket
on the rear of the amplier. You will need a mains supply
for both units.
NOTE: Connecon of a PSX-R is detected automacally by
the amplier, so no internal adjustments are required.

Before changing the names of the inputs, we recommend
making a list of each input number with your preferred
name from the choices above before seng the names. Each
name may only be used once. When a name is assigned to
an input it will be removed from the list for other inputs.
NOTE:- There are two special funcon input names marked *.
‘Cyrus AV’ is reserved for the connecon of Cyrus surround
sound decoders to one of the analogue Inputs 1-6 and
should only be used for this purpose.
‘AV Direct’ is reserved for the connecon of non-Cyrus
surround decoders to an analogue input. This input name
must only be used for this purpose as the volume level
will lock to a very high seng (-6dB) when AV Direct is
selected.
Choose ‘No source’ from the list to name inputs which have
no source connected to them. When named ‘No Source’,
an input number will not appear in the input selector scroll
sequence or in the Zone 2 select sequence.
In addion, the name ‘Tape 3-Head’ will appear as an extra
opon in the naming list for Input 6, and the name ‘USB’ will
appear in the list for Input 11.
Input 11 auto-hide
The USB input has a special ‘auto-hide’ feature. If this feature
is switched on, the USB input will only appear in the input
selector scroll sequence when a valid source is connected to
the USB input. If no source is connected or if the source is
switched o, Input 11 will not appear in the sequence.

Volume and Balance
The level control e performs the dual funcons of volume
and balance.
Volume: In normal mode the level control sets the volume
in 1dB steps. A bargraph and a numeric scale at the top of
the display window show the current volume seng. The
last used volume seng is stored when the unit is set to
standby.
If the volume is set to an abnormally high volume level
(greater than –15dB) before entering standby, the level will
be reduced automacally to a safer level of –15dB for next
use. Similarly, the volume will be reduced to a safer level if
the amplier was muted while set to a high volume seng,
or aer listening to headphones at a high volume seng.
Balance: Press the balance control key on the remote
control to change the mode of the front panel rotary control

volume, be sure to turn the level down before you switch to
normal loudspeaker operaon.
Playing music in Zone 2
As supplied from the factory, the Zone 2 system will always
play the same source as the main system. Changing the
main system source will also change the source playing in
