Bi-amplification
For convenience of connection in applications such as Bi-Amplification the
Chain outputs
e
and
d
allow more than one SmartPower to be connected to
a Pre-Amplifier.
The Chain facility can be used with two or more
SmartPowers for Bi/Tri-
amping by connecting the Chain output of the first SmartPower to the inputs of
the next
SmartPower
. Such a system provides the sonic benefits of totally
separate power amplification for the bass and treble units of the loudspeakers.
When adding additional
SmartPowers
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
SmartPower
. 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.
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.
MC-Bus connection
Connecting the MC-BUS sockets
c
of the
SmartPower
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).
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.

Switching On
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.
When power is applied, the STANDBY key
1% may be used for power control.
The Standby light
1^
shows red when the
SmartPower
is in Standby and green
when operational.
In addition to manual power control from the STANDBY key, the
SmartPower
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
SmartPower 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 SmartPower to a Cyrus system which includes a Preamplifier,
Integrated amplifier or Surround decoder. A number of
SmartPowers
may be
connected in this way to provide remote standby control of all the system
power amplifiers.
FRONT PANEL INDICATORS
MONO Indicator
The MONO Indicator
1&
will glow red if the rear panel STEREO/MONO switch
h
is set for MONO Operation. This switch can be operated only when the
SmartPower is in Standby. Operating it at any other time activates the fault
indication system .
