INTERCONNECTION
• Connect the RCA lineouts of the headunit with the RCA jacks LINE INPUT of the amplifier with appropriate high-value RCA cables.
If your headunit 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.
• Ensure by any means, that the total impedance load of subwoofer is not lower than 1 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.
MODE SWITCH
• The MODE switch must be in Position MASTER .
LEVEL CONTROLLER
• Turn the 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 LEVEL controller clockwise until you hear some distortion.
• Then turn back the LEVEL controller slightly until you hear a cleaner sound.
EXTENDED BASS CONTROL
• The SUB BOOST controller adjusts the bass enhancement between 0db and +18dB.
• A too high bass boost may cause clipping/distortion and damage on the loudspeakers and also may harm your hearing abilities.
Use this controller carefully!
• Attend therefor the further information (EXTENDED BASS CONTROL) on page 19 (Section #5).
LOW PASS CONTROLLER
• The LOW PASS 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.
INTERCONNECTION EXAMPLE Low Pass-Mode (Standard Subwoofer Operation)
Connect the bass remote
controller and the
remote terminal on the amplifier
with the enclosed cable.
Connect stereo RCA output
(R/L or SUB OUT)
of the headunit with
LINE INPUT R/L of the amplifier
R L
Subwoofer
1 – 8 Ohms
Switch setting =
MASTER
A additional subwoofer can be
connected to the non-occupied
speaker outputs. In this case
ensure a impedance of 2 - 8 ohms
per subwoofer.
NOTE!
