connecting the ENABLE OUT to the ENABLE IN of the next amplifier. A mating connector is shipped with the amplifier.
13.FAN GRILL
A continuously
intake! The fan operates only when the amplifier heat sinks require cooling.
OPERATION
AC MAINS CIRCUIT SIZE REQUIREMENTS
Power requirements for ICA™ amplifiers are rated at “idle”, 1/8 power (“typical” music conditions), 1/3 power, and maximum rated power. The maximum power current draw rating
is limited by the amplifier’s circuit breaker. Consult the specification sheet for the current that each amplifier will demand. AC mains voltage must be the same as that indicated on the back of the amplifier. Damage caused by connecting the amplifier to improper AC voltage is not covered by any warranty. NOTE: Always turn off and disconnect the amplifier from the mains voltage before making audio connections. As an extra precaution, have the input attenuators turned down during initial power up.
COOLING REQUIREMENTS
ICA Series amplifiers use a
panel, and exhausts through slots on the front panel. The fan will remain inactive until internal operating temperature rises above 45º C (113º F). Make sure there is enough space around the back of the amplifier to allow air to enter. NOTE: If the amplifier is rack mounted, do not use doors or covers on the front or back without pressurizing the back of the rack. Whatever type of rack you are using, make sure that heated air can escape freely, and that there is no resistance to the intake of cool air through the back grill. Intake and exhaust air must flow without resistance.
HIBERNATION™
All ICA Series amps feature Hibernation circuitry. Current draw and thermal emissions are at a minimum when the absence of input signal is sensed for more than a minute. Once signal is present, Hibernation instantly restores the amplifier to normal. Current draw specifications while Hibernation is active are included in specifications under Idle Current Draw.
THERMAL EMISSIONS
The system installer or designer should specify system cooling needs. Refer to the specifications at the back of this manual for specific thermal emissions figures.
INPUT CONNECTIONS
The input connector accepts balanced and unbalanced audio signals. For use with an unbalanced source, tie the inverting
