Application Notes
Things to check before you plug the amplifier in
Main AC power
- check that the voltage marked on your amplifier is the
same as the voltage at the power point. It is a good idea to check this
before plugging the amplifier into the power point. Be especially careful
of plugging into unchecked ‘piggyback’ plugs, power distribution boxes
or extension cables.
Your warranty does not cover damage caused by incorrect wiring.
Make sure the amplifier is connected to the same AC power supply and
Earth/Ground as the rest of the system, otherwise you may set up a
Ground loop hum.
The CP550 weighs approximately 11 kilos/24 lbs, and the CP850 12kilos/
26 lbs. We strongly recommend that you use the rear mounting slots as
well as those on the front panel.
All these amplifiers have cooling fans that force air around and through
the heatsinks. There are 2 fans on each model in the Cinema Pro series
Air flow diagram
It is
extremely
important that you ensure that there is
unrestricted
air access
to these fans, and also
unrestricted
air exit path. Clean the fan filters regular-
ly or at the first sign of becoming clogged.

• Heavy Duty Rear rack ears for four point racking
All Cinema Pro amplifiers have sufficient fan cooling capacity built in,
and need no extra external fan cooling to operate normally. Their com-
pact ‘UltraFin’ heatsink provides massive surface areas for rapid cooling
and stable temperatures.
BUT...
When racking up these amplifiers, a you MUST allow space for the air to
exit from the
rear
of the amplifier. Remember that Power = Heat, and
Maximum air flow = successful heat management.
