4-Channel-Mode Stereo Front- and Rearsystem
RCA & Speaker wiring:
• Connect the LINE INPUT of the amplifier to the head unit line output with two appropriate good quality RCA cables.
• Connect the speakers with appropriate wires to the terminal block (SPEAKER OUTPUT - CH1 + and - CH2 + and - CH3 and -
CH4 +) of the amplifier.
• The minimum final speaker impedance must not be lower than 2 Ohms per channel. 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
X-Over Switch CH1/2 & CH3/4
• By using bigger speaker systems (20cm), set the switch on FULL-position (FULL RANGE Signal).
• By using smaller speaker systems (
8.7cm - 16cm), set the switch on HP-position (HIGH PASS Signal).
The cut-off frequency should be between 60Hz - 150Hz. Adjust the level by the LOW PASS-contoller.
• In this configuration the LOW PASS - Mode is out of function.
Input Level CH1/2 & CH3/4
• 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 & CH3/4
• This controller should be set to 0dB-position.
Bass Remote
• The provided Bass Remote is not required in this configuration.
