Owner`s manual

1-Channel-Mode: 1 Subwoofer / Mono bridged

Cable Connections:

• Connect the INPUT Terminals of the amplifier to the head unit subwoofer output with good quality RCA cables.

• Connect the speakers with the terminal block (– BRIDGED +) of the amplifier.

• The minimum final speaker impedance must not be below 4 Ohm per channel. Too low speaker loads

result in too high heat dissipation and may cause the amplifier run into protection status.

• Please observe speaker channel and polarity as printed by the speaker terminal block.

Incorrect phasing of the speakers results in total loss of bass response.•

FILTER - Switches & Controls

• In 1-Channel-Mode in Mono select FILTER to "LP", which eliminates the higher frequencies.

The recommended crossover frequency ranges between 60 - 100Hz, depending on the size and response of the Subwoofer.

The Lowpass adjustment can be done with the XOVER control.

GAIN - Control

• Turn the GAIN control on the amplifier to "MIN." position.

• Turn the head unit volume control to about 80-90% of its full setting.

• Turn the GAIN control clockwise until you hear some distortion.

• Then turn back the GAIN control slightly until you can hear clean sound.

BASS-EQ - Control

• The BASS-EQ control increases the bass level from "+/– 18dB". Caution! Please use the Bass-Boost carefully.
