Do not connect loudspeaker cables with the vehicle 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 EXAMPLE 2-Channel Mode: 1x Stereo System (Front or rear)
INTERCONNECTION
• Connect the RCA lineouts of the headunit with the RCA jacks LINE INPUT of the amplifier with appropriate high-value RCA cables.
• Connect the front- or rear speakers with the speaker outputs (SPEAKER 1CH - and + 2CH -) by using appropriate wires.
• 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.
CROSSOVER SETTINGS
• 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
• 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 .
