INTERCONNECTION
• Connect the RCA lineouts of the head unit with the RCA jacks LINE IN CH 3 and CH 4 of the amplifier with appropriate
high-value RCA cables. If a separate SUB OUT from your head unit is available, use this as line output.
• Connect the subwoofers with the SPEAKER OUTPUTS CH1/2 + BRIDGED - and CH3/4 + BRIDGED -.
• Always ensure that the total impedance load per channelpair is not lower than 4 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.
CROSSOVER SETTINGS & BASS BOOST CONTROLLER
• The X-OVER switch of CH1/2 must be in position DUPE an X-OVER switch of CH3/4 must be in position LP..
Note: All controllers (BASS BOOST, HP, LP) except LEVEL are without function. All settings will be synchronized with CH3/4.
• The cut-off frequency ist adjustable with the LP controller of CH3/4 and should be set between 60 to 100 Hz, depending on the
size of the subwoofer.
• The BASS BOOST of CH3/4 controller adjusts the bass enhancement between 0db and +12dB.
LEVEL CONTROLLER CH1/2 & CH3/4 (SUBWOOFER 1+2)
• Turn the LEVEL 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 controller clockwise until you hear some distortion.
• Then turn back the LEVEL controller slightly until you hear a cleaner sound.
BASS REMOTE (SUBWOOFER 1+2)
• The enclosed BASS REMOTE CONTROLLER adjusts the bass-level e.g. from the driver's seat.
Please use only the enclosed bass remote controller and cable.
NOTE
Use the bass boost with care.
A high bass boost level may cause damages to your speakers and hearing abilities.
