Preparations for Installation

Before installing the SmartPower check that the following items are included in
the accessory box.
•
Guarantee Card (with instruction manual)
• Power Cable
•
2 MC-Bus phono cables

Connecting to the AC Mains Supply
Connect the socket on the AC Power cable to the Power inlet 1@ on the rear panel of
the SmartPower. Now connect the cable to a suitable AC power point.
The mains power switch 1$ on the rear panel of the SmartPower 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.
Connecting a Cyrus PSX-R Power Supply (Optional)
Connect the umbilical cord of the PSX-R to the 5-pin input socket of the
SmartPower 1!. When correctly fitted, the connector will latch into place.
Two channel or Single channel high power operation
The SmartPower may be configured as either a two channel (stereo) amplifier
or as a single channel (mono) amplifier for higher power applications. The
SmartPower is factory set for stereo operation.
Stereo systems
Stereo systems may be set up with either a single SmartPower set for two
channel (stereo) operation or twin SmartPowers set for single channel (mono)
operation.
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 SmartPower 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.
Note: Ensure all equipment is disconnected from the power before any
connections or disconnections are made.

Input Connection

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 SmartPower'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 SmartPower
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 SmartPower. Connect the right output of the
preamplifier to the 'M' Mono input f of the right channel SmartPower.

Loudspeaker Connection

Fitting the speaker plugs
Check for polarity indicators (+ and -) on the loudspeaker cable and fit the
plugs provided. Observe any signal directionality markings indicated on the
cable. If an arrow is printed on the cable it should point toward the
loudspeaker.
If additional or replacement speaker plugs are required for the SmartPower
ensure that the correct 'BFA' type are purchased.
Two channel stereo speaker connections
Connect the left loudspeaker to the rear panel sockets 1) (red speaker plug)
and i (black speaker plug) of the SmartPower. Connect the right loudspeaker
to the rear panel sockets a red speaker plug) and b (black speaker plug) of
the SmartPower.
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.
Single channel mono speaker connections
Connect the left loudspeaker to the left SmartPower using the panel sockets
marked M+ 1) (red speaker plug) and M- a (black speaker plug).
Repeat this procedure to connect the right channel speaker to the right
channel SmartPower. Fig 4b shows a wiring schematic for a bi-wired system
using mono amplifiers.
Audio-Visual multi-channel systems
Connect each SmartPower in turn to the system speakers, following the two
channel or single channel instructions above, as appropriate.
