Dust filter
The dust filters remove large particles from the air at the air intake.
Overload indicator
This indicator alerts the user to distortion in the signal. Under normal
operating conditions the indicator is not illuminated. When an unacceptable
level of distortion is detected, the indicator flashes red. The IOC (Input/
Output Comparator) circuit compares the waveform of the input signal to
that of the output. If there is a difference (or distortion) of 0.05% or more, the
indicator flashes brightly with a 0.1 second hold delay. Another IOC function
is to indicate input overload. If the input signal is too large the indicator will
flash brightly (with a 0.5 second hold delay) to indicate input overload.
Power indicator
This indicator illuminates red when the amplifier is powered on.
Power switch
Depress this push-button to turn the amplifier on or off. When turned on, the
output is disabled for approximately four seconds to protect your system from
start-up transients.
Note: To make any changes in this delay, contact AE AE Techron.-
