Caution
Please avoid to connect speaker (-) to the ground or vehicle chassis.
3-Channel-Mode: 2 Speakers / Stereo & 1 Subwoofer / Mono bridged
Interconnect Cable Checklist
• Connect the head unit line outputs with good quality RCA to RCA cables to the LINE INPUT SECTION
CH1/2 & CH3/4 of the amplifier.
• Connect the speakers with the terminal block (SPEAKER OUTPUT + CH1 - and + CH2 -)
of the amplifier.
• Connect the subwoofer with the terminal block (SPEAKER OUTPUT + MONO BRIDGED - from CH3/4)
of the amplifier.
• The minimum final speaker / subwoofer impedance must not be below 2 Ohms / 4 Ohms mono.
Too low speaker loads results in too high heat dissipation and may cause the amplifier runs into
protection-mode.
• 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.
FILTER - Switches & Control Channel 1/2
If larger than Ø 20 cm speakers are used, the FILTER selector should be set on "OFF" (Full-range).
For all smaller speakers (Ø 8.7cm - Ø 16cm) the FILTER selector should be set on "HP", which eliminates the lowest frequencies
and protects the speakers from damages. Set the crossover-frequency between 60Hz - 150Hz, depending on the size of the installed
speakers. The Highpass adjustment can be done with the HP control. The crossover-frequency is continously variable
from 15Hz - 1KHz.
FILTER - Switches & Control Channel 3/4
In 1-Channel-Mode in Mono the FILTER selector should be set on "LP", which eliminates the higher frequencies.
The recommended crossover-frequency should be between 60Hz - 150Hz, depending on the size and response of the subwoofer.
The lowpass adjustment can be done with the LP control. The crossover-frequency is continously variable from 50Hz - 500Hz.
When you use this setting the HP control is activated as a subsonic-filter. This filter eliminates too low frequencies. The threshold is
continously variable from 15Hz up to 1KHz and should be between 15Hz and 50Hz..
TWIN SUB - Switch
• This switch should be set on "OFF" - position.
BASS REMOTE - Switch
• This switch should be set on "ON" - position, if you want to use remote control. When this switch is set on "ON" - position
BASS BOOST - Control of the amplifier is out of function.
INPUT MODE - Switch
• This switch should be set on "4CH" - position, when you use two RCA to RCA cables. This switch should be set on "2CH" - position, when
you use one RCA to RCA cable. Use the inputs CH3 & CH4 when you only use one RCA to RCA cable for connection with the head unit.
INPUT GAIN - Control Channel 1/2 & Channel 3/4
• Turn the INPUT GAIN - controls on the amplifier to "MIN." - position.
• Turn the head unit volume control to about 80-90% of its full setting.
• Turn the INPUT GAIN - controls clockwise until you hear some distortion.
• Then turn back the INPUT GAIN - controls slightly until you can hear clean sound.
BASS BOOST - Control Channel 3/4
• The BASS BOOST controls the bass level (only CH3/4) from "0dB - +18dB" at 45Hz.
REMOTE CONTROL - Channel 3/4
• Allows to control Bass Boost via remote control from any location, e.g. from driver's seat.
