Connecting to the AC Mains Supply

Connect the socket on the AC Power cable to the Power inlet ⑩ on the rear panel of the SmartPower. Now connect the cable to a suitable AC power point.

The mains power switch ® 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 ^⑪ . 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 ⑧ to Stereo. Connect a stereo phono interconnect from the output of the preamplifier to the SmartPower's left and right inputs ④ and ⑦. 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 ⑧ on both amplifiers to Mono. Connect a single phono interconnect from the left output of the preamplifier to the 'M' Mono input ⑥ of the left channel SmartPower. Connect the right output of the preamplifier to the 'M' Mono input ⑥ 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 ⑩ (red speaker plug) and ⑨ (black speaker plug) of the SmartPower. Connect the right loudspeaker to the rear panel sockets ① red speaker plug) and ② (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+ ⑩ (red speaker plug) and M- ① (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.

Bi-amplification

For convenience of connection in applications such as Bi-Amplification the Chain outputs ⑤ and ④ 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 ⑤ and ④ to the inputs ④ and ⑦ of the new SmartPower. For single channel (mono) chain installations, connect the 'M' chain output ⑤ of each Mono amplifier to the 'M' Mono inputs ⑥ 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 ③ 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.

OPERATION

Key to the front panel drawing (Fig.2)

Switching On

The mains power switch ⑭ 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 ¹⁵ may be used for power control. The Standby light ¹⁶ 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 ③ 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 ⑰ will glow red if the rear panel STEREO/MONO switch ⑧ 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.

FAULT INDICATION SYSTEM

The SmartPower 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.

FAULT INDICATIONS

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.	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.
Standby light flashing Green
A fault has been reported from the PSX-R	Switch off the power to the SmartPower and the PSX-R Switch on again. If the problem does not clear, return both units to your Cyrus distributor for checking.
The PSX-R is disconnected or switched off.	Check there is power to the PSX-R and check the PSX-R connection to the SmartPower.
Standby light flashing Yellow / Red
The SmartPower has over heated.	Check the ventilation around the SmartPower. Allow the unit to cool down before re-applying power.
MONO light flashing
The STEREO/MONO switch has been changed whilst the amplifier is operating.	Return the switch to its original position.

If after taking remedial measures a fault condition remains, you should return the SmartPower to your Cyrus appointed dealer or an authorised Service Centre.
