NORMAL OPERATION:
Page 9/Diagram9 show you an example of a typical stereo set-up. Connect your inputs into channels one and two of the amplifier.
Connect your speakers to the outputs on the rear of the amplifier. Be sure that your front gain controls are turned down to their lowest
level (full counter-clockwise). Turn your amp on. Turn your input level up. Use your front gain controls to regulate the output volume. Be
sure not to raise the volume to the clip level however, an intermittent clip signal is acceptable.
MONO BRIDGE OPERATION:
Page 8/Diagram 8 give you a description of mono bridge set-up. Be sure you amplifier and all other equipment is shut off. Press
the Stereo/Mono switch to the in position (Page 5/Diagram 2 #7). Connect an input signal to channel one. Connect your speaker
across the red output binding post on the rear of your amplifier (See Page 7 Mono Bridge Set-Up). Turn your equipment on (your
amplifier should be the last piece you turn on). Apply an input signal to your amplifier. Turn channel two gain up. Use the channel
one gain to regulate your amplifier output.
PROTECTION:
LIMITER
During normal operation, the limiter does not affect the audio signal and is, in fact inaudible. It will allow brief clipping of peaks and
will only activate when continuous,hard clipping occurs. The limiter will then reduce the audio signal enough to minimize the amount of
clipping. When the signal amplitude decreases enough that clipping ends, the limiter will deactivate and cease its gain reduction.
SHORT CIRCUIT PROTECTION
The Output Short circuit protects the output devices from short circuits and stressful loads.
THERMAL PROTECTION
A single variable-speed fan provides adequate cooling. But if the heatsink temperature exceeds 90C., the amplifier will mute until
the amplifier cools down.
INPUT/OUTPUT PROTECTION
The input circuits are isolated by 10k resistors. An ultrasonic network decouples RF from the output and helps keep the amplifier
stable with reactive loads.
