INTERCONNECTION EXAMPLE LOWPASS-MODE: 1 x Subwoofer

ENG|OPERATIONAL INSTRUCTIONS

INTERCONNECTION

• Connect the RCA lineouts of the headunit with the RCA jacks LINE IN 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 OUTPUTS + / -) 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.

XOVER MODE SWITCH

• The XOVER MODE-Switch must be in Position LPF/BPF.

LEVEL CONTROLLER

• Turn the LEVEL controller of the amplifier to the MIN. 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.

BOOST CONTROLLER

• The BOOST controller adjusts the bass enhancement between 0db and +12dB @ 50 Hz.

• 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!

LPF (LOW PASS FILTER) CONTROLLER

• The LPF controller adjusts the cut-off point of the frequency range to above. The cut-off frequency is continuously

adjustable from 50 Hz to 250 Hz.

HIGHPASS/SUB SONIC CONTROLLER

• The HPF 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 10 to 100 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.

REMOTE BASS LEVEL CONTROLLER BLC-TR

• The enclosed remote BASS LEVEL Controller BLC-TR adjusts the bass-level e.g. from the driver’s seat.

Please use only the enclosed controller and cable.

Position XOVER MODE:

LPF/BPF

An additional subwoofer can be connected to the non-occupied

speaker outputs. In this case ensure a impedance of 4 - 8 ohms

per subwoofer.

NOTE!
