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 CH3/4 on the amplifier.
• Connect the speakers with SPEAKER CH 1 - and + CH 2 - and the subwoofer with the SPEAKER OUTPUT CH3/4
+ BRIDGED - of the amplifier.
• Ensure by any means, that the total impedance load of all speakers 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 amplifier operation.
CROSSOVER SETTINGS CH1/2 (STEREO-SYSTEM)
• Observe the settings on page 25.
CROSSOVER SETTINGS CH3/4 (SUBWOOFER)
• Observe the settings on page 26.
LEVEL CONTROLLER CH1/2 & CH3/4 (STEREO SYSTEM & SUBWOOFER)
• Turn the INPUT LEVEL controller of the amplifier to the 6V position.
• Turn the volume controller of the headunit to 80 - 90% of its full setting.
• Turn the INPUT LEVEL controller clockwise until you hear some distortion.
• Then turn back the INPUT LEVEL controller slightly until you hear a cleaner sound.
BASS BOOST CONTROLLER CH1/2 (STEREO-SYSTEM)
• The BASS BOOST controller must be turned to 0 dB position in this interconnecting example .
BASS BOOST CONTROLLER CH3/4 (SUBWOOFER)
• The BASS BOOST controller adjusts the bass enhancement between 0db and +12dB.
• A too high bass boost may cause clipping/distortion and damage on the loudspeakers and also may harm your hearing abilities.
Use this controller carefully!
