INTERCONNECTION EXAMPLE
Normal mode: subwoofer operation
FUNCTIONAL INSTRUCTIONS
INTERCONNECTION
• Connect the RCA lineouts of the head unit with the RCA jacks LINE IN of the amplifier with appropriate high-value RCA cables.
If your head unit is equipped with a additional subwoofer lineout (SUB OUT), it is recommended to use this lineout.
• Connect the subwoofer with the speaker outputs (SPEAKER / -) by using appropriate wires.
• Always ensure that the total impedance load on the speaker outputs is not lower than 2 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.
X-OVER MODE SWITCH
• The MODE switch must be in Position LP/BP.
LEVEL CONTROLLER
• 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 BOOST COBTROLLER
• The BASS BOOST controller adjusts the bass enhancement between 0db and +18dB.
LOW PASS CONTROLLER
• The LP controller adjusts the cut-off point of the frequency range to above. The cut-off frequency is continuously
adjustable from 35 Hz to 250 Hz.
SUB SONIC CONTROLLER
• 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.
PHASE CONTROLLER
• The PHASE controller allows to adjust the phasing between 0° and 180°.
Thereby you are able to adjust the subwoofer perfect to the vehicle’s acustics.
BASS REMOTE
• 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.

Connect stereo RCA output (R/L or SUB OUT)
of the head unit with LINE IN R/L of the amplifier
An additional subwoo-
fer can be connected to the
non-occupied speaker out-
puts. In this case ensure
a impedance of 4 - 8 ohms
per subwoofer.
