(4) MAINS POWER SOURCE
All CinemAcoustics Series power amplifiers are fitted with a single, heavy-duty, three-conductor line
cord and a conventional, three-terminal AC plug with a ground pin for 120 V products. For 100 V
and 220 V products, the line cord is fitted with the appropriate power connector. The power plug
should be connected to an independent circuit capable of supporting at least 15 amps for 100 V and
120 V service, and 7.5 amps for 220 V service. This is particularly important for applications where
the amplifiers will be continuously operated at, or near, their maximum power rating. The use of
extension cords should be avoided, but when necessary, use a three-wire type with at least a 14
WG wire size.
Always allow a qualified electrician to install any new electrical service. The ground pin of the
power plug is provided for your safety and should not be defeated. To prevent the risk of shock
or fire hazard, always be sure that the amplifier is properly grounded.
NOTE: FOR UK ONLY
As the colors of the wires in the mains lead of this apparatus may not correspond with the colored
markings identifying the terminals in your plug, proceed as follows: (1) The wire which is colored
green and yellow must be connected to the terminal which is marked by the letter E, or by the earth
symbol, or colored green or green and yellow. (2) The wire which is colored blue must be connected
to the terminal which is marked with the letter N, or the color black. (3) The wire which is colored
brown must be connected to the terminal which is marked with the letter L or the color red.
(5) CIRCUIT BREAKER
The power circuit breaker serves to protect the amplifier. The trip current value has been
carefully chosen to allow continuous operation at the rated power while still offering adequate
protection. Under normal conditions, the breaker will not trip unless there is a fault condition that
draws excessive mains current. Please note, however, that abnormal conditions such as a short
circuit applied to an output or continuous operation at overload or clipping will also cause the
breaker to trip. If you suspect that the breaker has tripped because of abnormal conditions, be sure
to remedy the cause of the fault before resetting the breaker. When tripped, the breaker button
extends outward nearly 1/2", and can be reset by pushing inward after a brief wait to allow the
breaker to cool down. When not tripped, the breaker button extends outward about 1/4". If the
