Cooling Fan Operation

Once the amplifier has been turned on, the power supply fan will start along with the
rear panel cooling fans. The CBA B series uses a forced air cooling system where air
is drawn in to the front grill and exhausted out of the rear of the amplifier. Temperature
sensitive fan circuits are used for optimal audible noise when the amplifier is in use.
When in standby mode the fans will operate at their slowest speed, once the amplifier
is set to, "Operate" mode, the RF modules will be enabled and start to generate heat.
The fans will slowly increase in speed until the amplifier has reached thermal
equilibrium.
Hints and tips: The air intake/exhaust should be kept clear at all times. If they are
blocked for any reason the amplifier will overheat and fault latch. Once the internal
amplifier temperature has cooled to within normal operating conditions the fault can be
reset and normal operation resumed.
