INTERCONNECTION
• Connect the RCA lineouts of the headunit with the RCA jacks LINE INPUT CH 1 and CH 2 of the amplifier with appropriate high-value
RCA cables. If a separate SUB OUT from your headunit is available, use this as LINE OUT.
• Connect the subwoofers with the SPEAKER OUTPUTS CH1/2 + BRIDGED - and CH3/4 + BRIDGED -.
• Ensure by any means, that the total impedance load of all subwoofers per channelpair is not lower than 4 ohms. Too low impedance
cause high temperature and will shut down the amplifier operation.
• Always ensure the correct polarity of the speakers. The interchange of plus and minus cause total loss of bass playback and could
damage the speakers.
INPUT MODE SWITCH
• Select the 2CH position on the INPUT MODE switch.

• Is the TWIN SUB switch on position ON, the controllers BASS BOOST, HIGH PASS, LOW PASS, LEVEL on CH1/2 are without function.
All settings will be synchronized with CH3/4. In switch position OFF, the bass remote works only on CH3/4.
