Cable connection
• Connect INPUT of the amplifier to the head unit line output with good quality RCA cables.
By connecting the RCA jacks OUTPUT with a additional amplifier, a full range signal will be
provided to the amplifier.
• Connect the subwoofer with the terminal block (SPEAKER OUTPUT + BRIDGED -) of the
amplifier.
• The minimum final subwoofer impedance must not be below 4 Ohm per channel pair. Too low
speaker loads result in too high heat dissipation and may cause the amplifier run into
protection.
• Please observe speaker channel and polarity as printed by the speaker terminal block.
Incorrect phasing of the speakers results in total loss of bass response.
X-OVER - Switch & Control
• For the operation with one subwoofer select at X-OVER "LP/BP" (LOW PASS/BANDPASS).
Adjust a frequency between 30Hz - 150Hz, depending on the size and response of the Subwoofer.
The Lowpass adjustment can be done with the LOW PASS control.
• The HIGH PASS - Control is working in this configuration as controller to adjust the Subsonic-Frequency (lower Frequency Cut-off).
Therewith a BANDPASS-Signal will be generated, where too low and not hearable frequencies will be eliminated.
Thereby a clean and powerful Bass-Signal will be generated. The adjustable level depends on the size and response of the
subwoofer and should be between 10Hz (no cut-off) and 30Hz (max. suggested Level).
NOTE: If the HIGH PASS - Level is higher than the LOW PASS - Level, no Sound is hearable.
LEVEL INPUT - Control
• Turn the LEVEL INPUT - Control on the amplifier to "4V" position.
• Turn the head unit volume control to about 80-90% of its full setting.
• Turn the LEVEL INPUT - Control clockwise until you hear some distortion.
• Then turn back the LEVEL INPUT - Control slightly until you can hear clean sound.
BASS BOOST - Control
• The BASS BOOST - Control adjusts the bass level at 45 Hz from 0 up to 12dB. Please use the Bass-Boost carefully.
BASS REMOTE
• The BASS REMOTE allows to control the Bass-Level for example from the driver's seat.
1-Channel-Mode: 1 Subwoofer / Mono bridged
Caution
