This amp features gold-plated RCA type jacks for high
impedance input. Use these with car stereo output which uses RCA type
connector cables.
If your car stereo jacks RCA type output, use this adaptor to connect the
high-low level input adaptor to connect the speaker output leads of car
stereo and the RCA input jacks of amp.
This amp features gold-plated RCA jacks for AUX line outputs. Use these
outputs. Use these for unlimited system expansion to the next CHOPPER.
This indicator is illuminated in GREEN when power is applied.
This indicator is illuminated in RED when the built-in protection circuitry
is actirated.
The fuse protects the amplifier and your car's electrical system from short
circuit conditions.
Use these connectors to deliver power, ground, and remote turn-on control
to the amplifier.
These terminals are 14K gold plated to guarantee high conductivity and
minimum signal loss.

When used with normal, full range system, set this switch to "FULL" .
If you wish to use the internal crossover to power a driver or specific
frequency range, use the "LPF"or "HPF" FOR the "LOWPASS" OR
HIGHPASS" settings.
Enables the matching of input levels to the output levels from head unit
(or other signal source). The input sensitivity of adjustment ranges from
6V to 200mV.
When crossover mode selector is in HIGHPASS mode, this control sets
the lower frequency limit for audio program sent to the speakers.
When crossover mode selector is in LOWPASS mode, this control sets
the upper frequency limit for audio program sent to the speakers.
The crossover is continuously variable adjustment from 40 t0 250 Hz.
This selector switch permits the bass level an increase of 18dB.
This control permits adjustment of the bass level up to an increase of
approximately up to 18dB.
When the sub sonic selector switch is in "ON" mode, this filter control
permits continuously variable adjustment from 10 to 100Hz.
