Connect RCA cable
from head-unit with
RCA input INPUT).
Cable connection
• Connect INPUT of the amplifier to the head unit line output with good quality RCA cables.
If your head unit doesn't have RCA Outputs you can connect the Speaker Outputs of the head
unit with the INPUT HIGH LEVEL of the amplifier.
• Connect the speakers with the terminal block (SPEAKER OUTPUT + L - und + R -) of the
amplifier.
• The minimum final speaker impedance must not be below 2 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
If larger than 20 cm speakers are used, the "FULL" position is recommended.
• For all smaller speakers (8.7cm - 16cm) the "HP"-Position (HIGH PASS) is recommended, which
eliminates the lowest frequencies and protects the speakers from damage. Set the crossover-frequency
between 60Hz - 150Hz, depending of the size of the installed speakers. The Highpass adjustment can be
done with the HIGH PASS control. In this configuration example the LOW PASS control is not used.
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
• Turn the BASS BOOST control into “0dB” - position.
