when used with normal, full range systems, set this switch to “FULL”. If you wish the internal crossover to power a driver of specific frequency range , use the “LOWPASS” or “HIGHPASS” settings.

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 upper frequency limit for audio program sent to the speakers.

use this control to match the outputs of you 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.

this amp features gold-plate 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 control permits adjustment of the bass level up to an increase of approximately 18 dB.

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 conductivityRand minimum signal loss.
