1 & 10 – HIGH PASS FILTER SWITCHES
Separate switches on each channel to enable highpass filters. Highpass
filters cut off the lowest frequencies to eliminate rumble and prevent
excess speaker excursion. The filter is enabled when the switch is
pushed in.
2 & 11 – HIGH PASS FILTER STATUS LEDS
Separate indicators on each channel illustrate the highpass filter status.
The LED is dark when the filter is not engaged. A Red color indicates the
cutoff is set at 40Hz, green indicates the cutoff is set at 80Hz.
3 & 12 – HIGH PASS FILTER CUTOFF FREQUENCY
SELECTOR SWITCHES
Separate switches for each channel select the highpass filter cutoff
frequency. When the switches are out, the cutoff is set at 40Hz. When the
switches are in, the cutoff is set at 80Hz.
5 – LEVEL CONTROL DEFEAT
When the switch is in, the level controls are set to 0dB attenuation no
matter what the position of the knobs.
4 & 9 – LEVEL CONTROLS
Sets the amount of signal attenuation, down to a maximum of
-100dB.
6 – SIGNAL LEVEL AND DIAGNOSTIC LEDS
An array of indicators that show the operational status of the amplifier
and the signal level.
PROTECT: Whenever a very low impedance (short circuit) is detected on either of the
outputs, or an over voltage, under voltage or over current situation is detected the amplifier
will protect itself and connected loads by immediately ceasing to drive the output stage.
READY: The amplifier is operational.

THERMAL: Whenever the output section and/or the power transformer exceeds preset
thermal limits, the amp is disabled and will resume once it has cooled.
SIGNAL: Indicates a signal is detected at the input.
–12dB: Indicates the output has reached a level 12dB below rated power.
–9dB: Indicates the output has reached a level 9dB below rated power.
–6dB: Indicates the output has reached a level 6dB below rated power.
–3dB: Indicates the output has reached a level 3dB below rated power.
0dB: Indicates the amplifier is producing full output (or slightly below, depending on load
impedance).
CLIP: Indicates the output signal is reaching approximately 1% distortion.
7 – CLIP LIMITER SWITCH
When the switch is "In" the clip limiter is enabled.
8 – CLIP LIMITER STATUS LED
Indicates when the clip limiter is enabled.
13 – 'STANDBY' LED
Indicates that the amp is in Standby mode. When in Standby mode, the
amplifier is turned "OFF", but the AC Mains are connected and the
amplifier waits for a DC voltage at the Sequence connector on the rear of
the amp. Once a DC voltage is applied to the Sequence connector, the
amp turns "ON" and begins its start-up diagnostics and upon completion
is ready for use.
14 – POWER SWITCH
A three-position switch used to select the power operation mode. In the
center position, power is off. In the up position, power is on. In the down
position, amp is set to standby mode.
