X-Over-Switch (CH1/2 Subwoofer 1 & CH3/4 Subwoofer 2)

• Switch to the LP/BP-position (LOW PASS/BAND PASS), that the higher frequencies are cut off. The cut-off frequency can be

selcted by the LOW PASS-controller. In LP/BP-Mode the HI PASS-controller is working also as Subsonic-Filter. The Subsonic

frequency can be selected by the HI PASS-controller.

Input Level (CH1/2 Subwoofer 1 & CH3/4 Subwoofer 2)

• Turn the LEVEL control of the amplifier to 6V position.

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

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

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

Bass EQ (CH1/2 Subwoofer 1 & CH3/4 Subwoofer 2)

• This Controller regulates the Bass Boost from 0 - 18 dB.

Caution! Please use the Bass-EQ carefully. The additional boost may result in clipping or overload.

Bass Remote (CH3/4 Subwoofer 2)

• The provided Bass Remote regulates the Bass Level of CH3/4 from f.i. the driver's seat.

Speaker & RCA Connections

3-Channel-Mode 2 Mono Subwoofer bridged

RCA & Speaker wiring:

• Connect the LINE INPUT of the amplifier to the head unit line output with appropriate good quality RCA cables.

• Connect the speakers/subwoofer with appropriate wires to the terminal block (SPEAKER OUTPUT/ - CH1/2 - Mono bridged +

and the subwoofer with CH3/4 - Mono bridged +) of the amplifier.

• The minimum final subwoofer impedance must not be lower than 4 Ohms per channelpair. Too low speaker loads result in too

high heat dissipation and may cause the amplifier run into protection.

• Please observe correct speaker channels and polarity as printed by the speaker terminal

Caution!

Do not connect speaker (-) to the ground or vehicle's chassis.
