INTERCONNECTION EXAMPLE 3-Channel Mode: Stereo System bridged + Subwoofer
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.
NOTE: Due to the loudspeakers in bridged mode on channel pair 1/2 and 3/4, the RCA line input must be connected like the following:
1.) Split the stereo RCA output (FL or RL) of the headunit with a Y-connector and connect the jacks
with LINE INPUT CH1 / CH3 of the amplifier
2.) Split the stereo RCA output (FR or RR) of the headunit with a Y-connector and connect the jacks
with LINE INPUT CH2 / CH4 of the amplifier
INTERCONNECTION SPEAKERS
• Connect the front- or rear speakers with the speaker outputs (SPEAKER OUTPUT CH1/2 + BRIDGED - and CH3/4 + BRIDGED -).
• Ensure by any means, that the total impedance load of the bridged speakers is not lower than 4 ohms per channel pair.
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 OUTPUT + 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 4CH position on the MODE switch in this example. 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 (bridged channel left) and CH3/4 (bridged channel right)
• 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 (bridged channel left), CH3/4 (bridged channel right) 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.
