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 O BRIDGED -) by using appropriate wires.
• Ensure by any means, that the total impedance load of the channel-pair 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.
CROSSOVER SETTINGS
• In the mono/subwoofer mode the X-OVER MODE switch must set to the LPF/BPF position (Lowpass/Bandpass mode), thereby the
higher frequencies will be eliminated. The cut-off frequency ist adjustable with the LPF controller and should be set between
60 to 100 Hz, depending on the size of the subwoofer.
• In the lowpass mode the HPF controller works also as subsonicfilter, that eliminates the ultra-low, not hearable and harmful
frequencies to generate a bandpass signal (Bandpass mode). The subsonic frequency should be set between 15 to 40 Hz, depending
on the size of the subwoofer. NOTE: If this value is higher than the lowpass setting, no sound is hearable.
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!
REMOTE BASS LEVEL CONTROLLER BLC-TSi
• The enclosed remote BASS LEVEL Controller BLC-TSi adjusts the bass-level e.g. from the driver’s seat.
Please use only the enclosed controller and cable.
The remote controller works as level attenuator and if the knob is on MAX position, the actual level which is set by the LEVEL controller
on the amplifier will be played back. By turning the knob counter-clockwise the level will be attenuated and lower.
