2 channel amplifier

crossover mode selector

when used with normal, full range systems, set this switch to “FULL.” If

 

you wish to use the internal crossover to power a driver of specific frequency

 

range, use the “LOWPASS” or “HIGHPASS” settings.

input level control

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.

low pass frequency control

when the crossover selector switch is in “low pass” mode, this control sets

 

the upper frequency limit for audio program sent to the speakers.

high pass frequency control

when the crossover selector switch is in “high pass” mode, this control

 

sets the lower frequency limit for audio program sent to the speakers.

bass boost level control

this control permits adjustment of the bass level up to an increase of

 

approximately 18 dB.

low level inputs

this amp features gold-platedRCA input jacks for high impedance input.

 

Use these with car stereo output which uses RCA-typeconnector cables.

high level inputs

if your car stereo lacks RCA-typeoutput 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-inprotection circuitry is activated.

power fuse

the fuse protects the amplifier and your car’s electrical system from short

 

circuit conditions.
