INTERCONNECTION EXAMPLE 4-Channel Mode: 2 x Stereo System (Front & Rear)
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.
REFERENCE NOTE
INTERCONNECTION
• Connect the RCA lineouts of the headunit with the RCA jacks LINE INPUT of the amplifier with appropriate high-value RCA cables.
• If there is only one stereo signal with two jacks available, you must use two y-connectors to splice the signal.
• 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 per channel.
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 CH1/2 & CH3/4
• For bigger speakers (more than 20cm) you can set the X-OVER switch to the FULL position (Full Range Signal).
• For smaller speakers (8.7cm - 16cm) you must set the X-OVER switch to the HP 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
60Hz to 150Hz, depending on the size of the speakers.
• The LOW PASS Controller is not in use in this interconnecting example.
LEVEL INPUT CONTROLLER CH1/2 & CH3/4
• 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
• The BASS BOOST controller must be turned to 0 dB position in this interconnecting example .
Connect the stereo RCA output (FL/FR and
RL/RR) of the headunit with LINE INPUTS
