EXAMPLE 3-Channel Mode: 1 x Stereo System & 1 x Mono Subwoofer bridged
Subwoofers
4 – 8 Ohm
Speaker
2 – 8 Ohms
INTERCONNECTION
• Connect the RCA lineouts of the headunit with the RCA jacks LINE INPUT of the amplifier with appropriate high-value RCA cables. If a
separate SUB OUT from your headunit is available, use this for the LINE INPUT CH1/2 on the amplifier.
As alternative you can connect the loudspeaker outputs of your headunit with the HIGH LEVEL INPUT. Never use the High Level Inputs
and the RCA inputs at the same time. This may damage the amplifier seriously. Attend therefor the descriptions on page 28.
• Connect the speakers with SPEAKER OUTPUT + CH 3 - and + CH 4 - and the subwoofer with the SPEAKER OUTPUT CH1/2
+ BRIDGED - of the amplifier.
• Ensure by any means, that the total impedance load of all speakers per channelpair (CH3 & CH4) is not lower than 2 ohms and the total
impedance load of the subwoofer (CH1 & CH2) is not lower than 4 ohms. Too low impedance cause high temperature and will shut down
the amplifier operation.
INPUT MODE-Switch
• Select the 4CH position on the INPUT MODE switch. If there is only one RCA stereo audio cable from the headunit available, connect
the CH1/2 RCA line inputs and select the 2CH position.
CROSSOVER SETTINGS CH1/2 (SUBWOOFER )
• Attend the regarding notes on page 28.

• Attend the regarding notes on page 25.
BASS BOOST CONTROLLER CH3/4 (STEREO SYSTEM)
• The BASS BOOST controller must be turned to 0 dB position in this interconnecting example .
