when used with normal, full range systems, set this switch to “FULL.” If
youwishtousetheinternalcrossovertopoweradriverofspecificfrequency
range, use the “LOWPASS” or “HIGHPASS” settings.
use this control to match the outputs of your head unit to the amplifier.
Starting with your head unit set at about the 2 o’clock position, increase
the amp level control until distortion begins to occur, and reduce slightly
from this point.
whenthe crossover selector switch isin “low pass” mode, this control sets
the upper frequency limit for audio program sent to the speakers.
when the crossover selector switch is in “high pass” mode, this control
sets the lower frequency limit for audio program sent to the speakers.
this control permits adjustment of the bass level up to an increase of
approximately 18 dB.
this amp features gold-plated RCA input jacks for high impedance input.
Use these with car stereo output which uses RCA-type connector cables.
if your car stereo lacks RCA-type output jacks, you may connect speaker
output leads to these input connectors.
this indicator is illuminated when power is applied.
this indicator is illuminated when built-in protection circuitry is activated.
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.
