4-channel-mode: 1 x Stereo-System (Front) and 1 x Stereo-System (Rear)
the head unit with INPUT CH1 / CH2 and CH3 / CH4
INTERCONNECTION
• Connect the RCA outputs of the head unit with the RCA jacks (INPUT CH1-4) of the amplifier with appropriate high-value RCA cables.
• Connect the front and rear speakers with the speaker outputs (SPEAKER OUTPUT + 1CH -, + 2CH - and + 3CH -, + 4CH -).
• Always ensure that the total impedance load on the speaker outputs 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.
INPUT MODE SWITCH
• Select the 4CH position on the INPUT MODE switch. If there is only one RCA stereo audio cable from the head unit available,
connect the CH1/2 RCA line inputs and select the 2CH position.
CROSSOVER SETTINGS CH1/2 & CH3/4
• When using bigger speakers (more than 20 cm) set the X-OVER switch to the FULL position (Full Range Signal).
• When using smaller speakers (8.7cm - 16 cm) 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 CONTROLLER CH1/2 & CH3/4
• Turn the LEVEL INPUT controller of the amplifier to the MIN position.
• Turn the volume controller of the head unit 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 must be turned to 0 dB position in this interconnecting example .
BASS REMOTE
• The enclosed BASS REMOTE CONTROLLER is not in use in this interconnecting example.
NOTE
Do not connect loudspeaker cables with the vehicle's chassis. Always ensure the correct polarity of all connections.
