INTERCONNECTION LINE INPUTS
• Connect the RCA lineouts of the headunit with the RCA jacks LINE INPUT of the amplifier with appropriate high-value RCA cables.
INTERCONNECTION SPEAKERS
• Connect the front- and rear speakers with the speaker outputs (SPEAKER 1CH -, + 2CH - and + 3CH -, + 4CH -).
• Ensure by any means, that the total impedance load of all speakers is not lower than 2 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.
INTERCONNECTION SUBWOOFER
• Connect the subwoofer with the speaker outputs (SPEAKER 5CH -) of the amplifier.
• Ensure by any means, that the total impedance load of of the subwoofer is not lower than 1 ohm. 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.
MODE SWITCH
• Select the 5CH position on the MODE switch in this example. If headunit is not equipped with a separate subwoofer output (SUB OUT),
connect the CH1/2 and CH3/4 RCA line inputs and select the 4CH position. Thereby the input signal on CH1/2 and CH3/4 will be routed
to the subwoofer channel (CH5) and the subwoofer signal will be filtered out.The use of Y-connectors is not required in this case.
CROSSOVER SETTINGS CH1/2 & CH3/4
• By using bigger speakers (more than 20cm) you can set the X-OVER switch to the FULL position (Full Range Signal).
• By using smaller speakers (8.7cm - 16cm) you must set the X-OVER switch to the HPF Position (Highpass Mode) to avoid any damage
by lower frequencies on the speakers. The cut-off frequency is adjustable with the HIGH PASS controller and should be set between
10Hz to 150Hz, depending on the size of the speakers.
LOW PASS CONTROLLER Subwoofer Channel CH5
• The LOW PASS controller adjusts the cut-off point of the frequency range to above. The cut-off frequency is continuously
adjustable from 30 Hz to 150 Hz.
SUBSONICFILTER CONTROLLER Subwoofer Channel CH5
• The SUB SONIC controller (Subsonicfilter) limits the ultralow and not hearable frequencies of the audiosignal to below, to avoid a
mechanical and electrical overloading on the subwoofer. The cut-off frequency is adjustable from 15 to 55 Hz and depends on the size
of the subwoofer.
BASS BOOST CONTROLLER Subwoofer Channel CH5
• 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!
BASS REMOTE CONTROLLER Subwoofer Channel CH5
• The enclosed BASS REMOTE Controller adjusts the subwoofer level e.g. from the driver’s seat.
Please use only the enclosed bass remote controller and cable.
LEVEL INPUT CONTROLLER CH1/2, CH3/4 and CH5
• Turn the LEVEL INPUT controller of the amplifier to the 5V 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.

INTERCONNECTION EXAMPLE 5-Channel Mode: Stereo Front- & Rear Subwoofer
Do not connect loudspeaker cables with the vehicle’s chassis. Always ensure the correct polarity
of all connections. The interchange of plus and minus cause total loss of bass playback and could
damage the speakers.
