Connecting a Cyrus Surround Sound decoder
If your system includes a Cyrus multi-channel surround sound decoder, it may
be connected through your stereo amplifier 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
amplifier. For this system to function correctly both the amplifier and the Cyrus
surround decoder must be included in an MC-BUS connection loop and the
'Cyrus AV' input name must be set for the input used (see 'MC-BUS' section
and 'Input names' in the 'Setup menu' section).
When set up in this way, the amplifier will automatically check for the
presence of the decoder when the 'Cyrus AV' input is selected, then lock its
volume setting to an appropriate level.
Connecting a Surround Sound decoder (other brand)
If your system includes a multi-channel surround sound decoder (but not a
Cyrus model), it may be connected through your amplifier 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
amplifier. For this system to function correctly, the 'AV Direct' input name
must be set for the input used (see 'Input names' in the 'Setup menu' section).
When set up in this way, the amplifier will automatically lock its volume setting
to a fixed 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
amplifier will be fixed at a very high level.
MC-BUS System
(Refer to fig 4)
a
Connecting the MC-BUS sockets
in an MC-BUS system provides unified
system 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 in
a daisy-chain. Complete the loop by returning the MC-BUS output of the final
component to the MC-BUS input of the first.
With MC-BUS connection established you can control the power function of
the entire system from the front panel or remote control. Selecting 'CD' from
the front panel will switch on the amplifier, the Cyrus power amplifier and a
Cyrus CD player. When the amplifier is set to Standby, the entire system will
also switch off.
When a Cyrus Surround Processor is included in the MC-BUS loop, setting of
the volume calibration level will take place automatically when the 'Cyrus AV'
input is selected. Refer to the handbook for the Surround Processor for further
details.
External Power Supply - PSX-R
The PSX-R is a unique DC power supply which will upgrade the sonic
performance of your amplifier. When an amplifier / PSX-R combination is
installed, analogue and signal related sections of the amplifier are powered
from this clean, stable power source while other requirements are supplied
internally. This ensures complete isolation of control circuits and sensitive
analogue sections reducing AC mains-borne noise and power supply ripple.
To connect the PSX-R to the amplifier, disconnect both components from the
mains, then plug the connector on the umbilical cord of the PSX-R into the
1!
Multi-Pole socket on the rear of the amplifier (
Fig.1). You will need a mains
supply for both units.
NOTE: Connection of a PSX-R is detected automatically by the amplifier, so
no internal adjustments are required.
