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.
SLAVE IN/MASTER OUT SWITCH
• The SLAVE IN/MASTER OUT switch must be in position
MASTER OUT
.
LEVEL 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 adjusts the bass enhancement between 0db and +12dB.
• 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!
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 40 Hz to 180 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.
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.
