Pb-1838Gx; Pb-738Gx; Input Sensitivity - Pyramid PB-1038GX User Manual

crossover mode selectors when used with normal, full range systems, set these switches to "FULL."
If you wish to use the internal crossovers to power a driver of specific
frequency range, use the "LOWPASS" or "HIGHPASS" settings.
input level controls use these controls 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 controls until distortion begins to occur, and reduce slightly
from this point.
low pass frequency controls 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.
high pass frequency controls when the one or both of crossover selector switch is in "high pass" mode,
one can set the lower frequency limit for audio program sent to the
speakers.
Remote Bass Boost Plug in the Remote Bass Boost Control wire in here.
bass boost level controls this control permits adjustment of the bass level up to an increase of
approximately 18 dB in either or both pairs of channels.
low level inputs this amp features gold-plated RCA input jacks for high impedance input.
Use these with car stereo output which uses RCA-type connector cables.
high level inputs if your car stereo lacks RCA-type output jacks, you may connect speaker
output leads to these input connectors.
power LED this indicator is illuminated when power is applied.
protection LED this indicator is illuminated when built-in protection circuitry is activated.
power fuse the fuse protects the amplifier and your car's electrical system from short
circuit conditions.
power terminals use these connectors to deliver power, ground and remote turn-on control
to the amplifier.
speaker connections these terminals are 14K gold plated to guarantee high conductivity and
minimum signal loss.
