when used with normal, full range systems, set this switch to “FULL.” If
youwishto use theinternalcrossoverto power adriverofspecific frequency
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.
when the crossover selector switch is in “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.

If you wish to use the internal crossovers to power a driver of specific
frequency range, use the “LOWPASS” or “HIGHPASS” settings.

when one or both of the crossover selector switches is in “low pass”
mode, one can set the upper frequency limit for audio program sent to
the speakers.

one can set 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 in either or both pairs of channels.
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.
