Back Panel – RCA Inputs, Power Connection and Speaker Outputs
1.
Power Terminals
– The power and ground connectors on the amplifier are platinum-plated and will accommodate up to
1/0 AWG wire, maximizing the input current capability of the amplifier.
2.
REMOTE Terminal
– This heavy duty, platinum-plated wire connector will accept wire sizes from 12 AWG to 24 AWG.
This terminal is used to remotely turn-on and turn-off the amplifier when +12V DC is applied.
3.
RCA Input Jacks
– The industry standard RCA jacks provide an easy connection for signal level input.They are platinum-plated
to resist the signal degradation caused by corrosion.
4.
Speaker Terminals
– These high current binding posts (
+
and
-
) will accept wire sizes up to 4 AWG.
Front Panel – Controls
5.
Gain Control
– The input gain control is preset to match the output of most source units. It can be adjusted to match output
levels from a variety of source units. Setting displayed at item 16 on the top panel status board.
6.
Variable Crossover
– Is a built-in 12dB/octave Butterworth filter selectable for Low-Pass (LP),All Pass (AP), or High-Pass (HP)
operation variable from 32Hz to 300Hz. Setting displayed at item 17 on the top panel status board.
7.
Infrasonic Filter Button Switch
– Pressing this switch in, switches on a 24dB/octave infrasonic filter designed to prevent fre-
quencies below the audio range from being applied to the subwoofer from the amplifier. Consequently improving subwoofer per-
formance and power handling, particularly in vented enclosures.
8.
Channel Link Button Switch
– Pressing this switch in, switches the inputs to a 2-channel mode, allowing connection to only
the Channel-1 and Channel-2 inputs with a full 4-channel output. Setting displayed at item 15 on the top panel status board.
NOTE:
When the Channel Link Button Switch is engaged, only the Channel 1-2 controls will function and the gain and frequency
displays on the top panel status board for channels 3 and 4 will turn off.

Output Display
– These LED needle simulation displays show the real-time output of the amplifier from - 00(infinity) to +2dB.
During normal operation the indicator should not reach +2dB, as this indicates clipping.
10.
Warm-Up
– This LED will be on while the unit warms up when it is first turned on. Depending on the available power, the unit
may take up to a minute to warm up.
11.
Thermal Protect
– This LED comes on if the amplifier reaches the third stage of thermal protection.The amplifier will shut
down to cool if this occurs.
