LOUDSPEAKER WIRING & CONNECTION
4-Channel Amplifier VE800.4 / VE1200.4
BALANCED INPUT CH 1&2 / CH 3&4
This Input can optionally be used with appropriate cables and
symmetrical signal transmitters. Please do not use this Input at
the same time as the RCA Inputs.
RADIO / HEAD UNIT
CONNECTION
• Connect the head unit line outputs (FRONT L & R and REAR L & R) with the RCA LINE INPUTs of the amplifier
with appropriate RCA cables.
• Connect the speakers with SPEAKER OUTPUT CH 1 ( – / +), CH 2 ( – / +) and the subwoofer with
SPEAKER OUTPUT CH 4 ñ and CH3 + of the amplifier.
• The final speaker impedance should not be lower than 1 Ohm (or 2 Ohm for the Subwoofer) per channel.
CONFIGURATION CHANNEL 1 & 2
• The threshold frequency for the HIGH PASS should be between 60Hz - 150Hz, depending on the size of speakers
and is adjustable by T5.
• When PHASE SHIFT is activated by T3 (Position ON) the acoustical center is adjustable by T1 and T2.
CONFIGURATION SUBWOOFER
•
T7 should be set to BAND PASS. The upper threshold frequency of the LOW PASS should be between
60Hz - 150Hz, depending on size of the subwoofer and is adjustable by T11. The lower threshold frequency
(Subsonicfilter) is adjustable by T12 (See page 32).
• When the Pushbuttons T9 & T10 are pressed, the slew rate of the frequency response is raised up to 24dB in
Mono mode (See page 32).
BASS BOOST
• F6 allows you to adjust the BASS BOOST between 0 and 18 dB. Please use the BASS BOOST carefully.
INPUT GAIN - Control
• Turn the INPUT GAIN - control (T6 & T8) on the amplifier to 9V-Position.
• Turn the head unit volume control to about 80-90% of ist full setting.
• Turn the INPUT GAIN - control (T6 & T8) clockwise until you hear some distortion.
• Then turn back the INPUT GAIN - control (T6 & T8) slightly until you can hear clean sound.

INPUT MODE
When you want to use
4 RCA
cabels Input mode switch (T5)
should be set on "4CH"-Position.
LINE OUT (F1)
Optional triggering to
use additional amplifiers.
Caution!
Be careful not to connect speaker (-) to the ground or vehicle chassis.
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.
