INTERCONNECTION EXAMPLE
3-channel-mode: 1 x Stereo-System and 1 x Mono Subwoofer
FUNCTIONAL INSTRUCTIONS
INTERCONNECTION
Connect the RCA lineouts of the head unit with the RCA jacks LINE IN of the amplier with appropriate high-value RCA cables.
If a separate SUB OUT from your head unit is available, use this for the LINE IN CH3/4 on the amplier.
Connect the speakers with SPEAKER OUTPUT + CH 1 - and + CH 2 -, and the subwoofer with the SPEAKER OUTPUT CH3/4
+ BRIDGED - of the amplier.
Always ensure that the total impedance load per channelpair (CH1 & CH2) is not lower than 2 ohms and the total impedance load
of the subwoofer (CH3 & CH4) is not lower than 4 ohms. Too low impedance cause high temperature and will shut down the
amplier operation.
