INTERCONNECTION EXAMPLE 1-Channel Mode: 1x Mono Subwoofer bridged
Subwoofer
4 – 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 your headunit is equipped with a additional subwoofer lineout (SUB OUT), it is recommended to use this lineout.
As alternative you can connect the loudspeaker outputs of your headunit with the HIGH LEVEL INPUT. Never use the High Level Input
and the RCA inputs at the same time. This may damage the amplifier seriously. Attend therefor the descriptions on page 28.
• Connect the subwoofer with the speaker outputs (SPEAKER OUTPUT + Mono bridged -) by using appropriate wires.
• Ensure by any means, that the total impedance load of the channel-pair 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.
CROSSOVER SETTINGS
• In the mono/subwoofer mode the X-OVER switch must set to the LP/BP position (Lowpass/Bandpass mode), thereby the higher
frequencies will be eliminated. The cut-off frequency ist adjustable with the LOW PASS controller and should be set between
60 to 100 Hz, depending on the size of the subwoofer.
LEVEL CONTROLLER
• Turn the LEVEL INPUT controller of the amplifier to the 4V position.
• Turn the volume controller of the headunit to 80 - 90% of its full setting.
• Turn the LEVEL INPUT controller clockwise until you hear some distortion.
• Then turn back the LEVEL INPUT controller slightly until you hear a cleaner sound.
BASS BOOST CONTROLLER
• 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!
REFERENCE NOTE
Do not connect loudspeaker cables with the vehicle chassis.
Always ensure the correct polarity of all connections.
Use the bass enhancement with care.
A high bass boost may cause damage to your speakers and hearing abilities.
