and i (black speaker plug) of the 8/X Power. Connect the right loudspeaker
to the rear panel sockets a (red speaker plug) and b (black speaker plug) of
the 8/X Power.
Connecting to the AC Mains Supply
Dual outputs are provided for the convenient connection of bi-wiring speaker
cables. Figure 4a shows a wiring schematic for a bi-wired stereo system.
Connect the socket on the AC Power cable to the Power inlet 1@ on the rear panel
of the 8/X Power. Now connect the cable to a suitable AC power point.
Single channel mono speaker connections
Connect the left loudspeaker to the left 8/X Power using the panel sockets
marked M+ 1) (red speaker plug) and M- a (black speaker plug).
The mains power switch 1$ on the rear panel of the 8/X Power should be left
on for normal operation, except when left unattended for a long period when it
should be switched off or disconnected from the AC supply.
Repeat this procedure to connect the right channel speaker to the right
channel 8/X Power. Fig 4b shows a wiring schematic for a bi-wired system
using mono amplifiers.
External Regulated Power Supply - PSX-R
The Cyrus PSX-R is a unique DC power supply which will upgrade the sonic
performance of your 8/X Power and enhance its current drive. When a 8/X
Power/PSX-R combination is installed, analogue and signal related sections
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.
Audio-Visual multi-channel systems
Connect each 8/X Power in turn to the system speakers, following the two
channel or single channel instructions above, as appropriate.
Bi-amplification
For convenience of connection in applications such as Bi-Amplification the
Chain outputs e and d allow more than one 8/X Power to be connected to a
Pre-Amplifier.
To connect the PSX-R to the 8/X Power plug the connector on the umbilical
cord of the PSX-R into the Multi-Pole socket on the rear of the 8/X Power (1!
Fig.1) You will need a mains supply for both units.
The Chain facility can be used with two or more 8/X Powers for Bi/Tri-amping
by connecting the Chain output of the first 8/X Power to the inputs of the next
8/X Power. Such a system provides the sonic benefits of totally separate
power amplification for the bass and treble units of the loudspeakers.
Two channel or Single channel high power operation
The 8/X Power may be configured as either a two channel (stereo) amplifier
or as a single channel (mono) amplifier for higher power applications. The 8/X
Power is factory set for stereo operation.
When adding additional 8/X Powers to a system, connect a quality RCA
phono interconnect from the Chain output RCA jacks e and d to the inputs
f and g of the new 8/X Power. For single channel (mono) chain
installations, connect the ‘M’ chain output e of each Mono amplifier to the ‘M’
Mono inputs f of the new amplifiers.
Stereo systems
Stereo systems may be set up with either a single 8/X Power set for two
channel (stereo) operation or twin 8/X Powers set for single channel (mono)
operation.
When the input connections to the new amplifier are complete, separate
connections may be made to the bass and treble units of the system
speakers. Fig 4c shows a wiring schematic for a bi-amped system using
stereo amplifiers.
Audio-Visual multi-channel systems
Both two channel and single channel high power modes may be employed for
the multiple channel requirements of audio-visual systems. Two channel and
single channel amplifiers may also be mixed in these systems if preferred, for
example- three 8/X Power amplifiers set for single channel (mono) operation
to drive the Front Left, Right and Centre channels and a single Two channel
(stereo) amplifier to drive both the left and right surround channels.
MC-BUS connection
Connecting the MC-BUS sockets c of the 8/X Power 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 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 (see
example system connections in Fig.3).
Note: Ensure all equipment is disconnected from the power before any
connections or disconnections are made.
Input Connection
With MC-BUS established you can control the power function of the system
from the front panel or remote control of the main Cyrus amplifier or Surround
Processor.
Two channel (stereo) operation
Set the STEREO/MONO switch h to Stereo. Connect a stereo phono
interconnect from the output of the preamplifier to the 8/X Power's left and
right inputs f and g. Be sure to observe colour coding of the plugs to keep
left and right channels correctly ordered.
Single channel (mono) operation
When switched for single channel mono operation, twin 8/X Power amplifiers
are necessary in a stereo system – one for the left and one for the right
channel.
Set the STEREO/MONO switch h on both amplifiers to Mono. Connect a
single phono interconnect from the left output of the preamplifier to the ‘M’
Mono input f of the left channel 8/X Power. Connect the right output of the
preamplifier to the ‘M’ Mono input f of the right channel 8/X Power.

Switching On
The mains power switch 1$ on the rear panel of the 8/X Power should be left
on for normal operation, except when left unattended for a long period when it
should be switched off or disconnected from the AC supply.
When power is applied, the STANDBY key a may be used for power control.
The Standby light b shows red when the 8/X Power is in Standby and green
when operational.
In addition to manual power control from the STANDBY key, the 8/X Power
also features a music sensing automatic power control which listens for the
presence of an input signal and will switch on if music begins to play. If the
8/X Power has been activated in this way it will reset to Standby five minutes
after the music has stopped.
Remote power control can also be enabled by connecting the MC-BUS
sockets c of the 8/X Power to a Cyrus system which includes a Preamplifier,
Integrated amplifier or Surround decoder. A number of 8/X Powers may be
connected in this way to provide remote standby control of all the system
power amplifiers.

Disabling the Music Sensor
In some installations a number of 8/X Power amplifiers may be driven from a
single preamplifier source to feed loudspeakers in several extension rooms.
In systems such as these it may be preferable to disable the Music Sensor to
prevent all amplifiers switching on when music commences.
FAULT INDICATION SYSTEM
The 8/X Power has a powerful protection system and fault indication system
designed to prevent damage to your hi-fi system and help you diagnose a
possible problem. If a fault persists, reset the amplifier via the rear panel
mains switch.
The user can disable the Music Sensor by holding the front panel Standby
key whilst switching on the unit at the rear. The amplifier will now respond
only to the front panel standby button and MC-BUS commands. The Music
Sensor will remain disabled until power is next disconnected from the unit.
FAULT INDICATIONS
The Music Sensor may also be permanently disabled by returning the 8/X
Power to your retailer or the Cyrus factory for an internal adjustment.
Standby light flashing Green / Yellow
This indicates overload in at least
one channel. If the problem is
temporary (e.g. excessive volume),
normal operation will resume after
ten seconds. If the fault indication
persists, there may be a problem
with the speakers or connections.
NOTE:- If MC-BUS connections are made to the 8/X Power the music sensor
is disabled automatically.
FRONT PANEL INDICATORS
MONO Indicator
The MONO Indicator c will glow red if the rear panel STEREO/MONO switch
h is set for MONO Operation. This switch can be operated only when the 8/X
Power is in Standby. Operating it at any other time activates the fault
indication system.
Standby light flashing Green
A fault has been reported from the
PSX-R
The PSX-R is disconnected or
switched off.
Standby light flashing Yellow / Red
The 8/X Power has over heated.
MONO light flashing
The STEREO/MONO switch has
been changed whilst the amplifier is
operating.
Switch off the power at the rear
panel and unplug the speaker
cables. If the fault indication clears
when power is re-applied, check the
loudspeakers, cables and plugs for
loose strands of wire causing a
possible short circuit.
Switch off the power to the 8/X
Power and the PSX-R Switch on
again. If the problem does not clear,
return both units to your Cyrus
distributor for checking.
Check there is power to the PSX-R
and check the PSX-R connection to
the 8/X Power.
Check the ventilation around the 8/X
Power. Allow the unit to cool down
before re-applying power.
Return the switch to its original
position.
If after taking remedial measures a fault condition remains, you should return
the 8/X Power to your Cyrus appointed dealer or an authorised Service
Centre.
