ESX vision2 Series - 4-Channel Mode: 4 Speakers; Stereo

4-CHANNEL-MODE: 4 Speakers / Stereo
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 or REAR L & R) with the RCA LINE INPUTs of the amplfier with
appropriate RCA cables.
• Connect the speakers with SPEAKER OUTPUT CH1 – and +, CH2 ñ and +, CH3 ñ and +, CH4 ñ- and + of the amplifier.
• The final speaker impedance not be lower than 1 Ohm per channel. Too low speaker loads results
in too high heat dissipation and may cause the amplifier run into protection mode.
CONFIGURATION CHANNEL 1 & 2
• The threshold frequency should be between 60Hz - 150Hz, depending on the size of the speakers, adjustable by T5.
• When PHASE SHIFT is activated by T3 (Position ON) the acoustical center is adjustable by T1 and T2.
CONFIGURATION CHANNEL 3 & 4
• For bigger speaker systems (Ø20cm plus) T7 should be set to FULL (Full Range-Signal).
• For smaller speaker systems (Ø8.7cm - Ø16cm), T7 should be set on HIGH PASS because the
loudspeakers could get damaged by too low frequencies. The threshold frequency should be
between 60Hz - 150Hz depending on speakers sizes and is adjustable by T5.
• The pushbuttons T9 & T10 should be set on 12dB-Position (not pressed).
• In this configuration LOW PASS (T11) and BASS BOOST (F6) should not be used.
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.
