General Installation Notes
The amplifier is generally mounted in the rear trunk area but can be mounted in any convenient area such as beneath a seat. Please be
sure to locate this unit where you have reasonable air circulation and protection from moisture. When considering the mounting location you
should minimize the length of the power and speaker leads. Minimizing both leads will yield a more reliable installation. It is also important
to ensure that the heat sink fins are not against a panel or a surface, preventing air circulation. Do not install the amplifier on a subwoofer
box or on vibrating parts of the vehicle, since the vibrations can cause damages to the amplifier's electrical components.
Installation of the amplifier
Mark the location for the mounting screw holes by using the amplifier as a
template. Drill holes at the marked locations and firmly fasten the amplifier
in place with the mounting screws supplied in the accessory kit. Before drilling
or cutting any holes, investigate the layout of your automobile thoroughly:
Take care when working near the gas lines, the hydraulic lines or
the electrical wiring at your car.
Electrical Connection
Ground (GND)
This wire is the electrical ground and must be fastened securely to the vehicle chassis. The best method is to use a threading sheet metal
screw since the threads cut into bare metal. Ensure that all paint or other insulation is removed around the hole area, and using self tapping
screw, securely affix the bare wire ends to the vehicle chassis. Use a piece of cable which is as short as possible - use the same gauge as
used for the +12V cable. Make sure that the connection is safe, a loose connection may result in amplifier noise and fault condition.
Remote (REM)
Many music sources have an output terminal for connection of the remote turn-on of the power amplifier. If a radio doesn't have a remote
turn-on feature, then you can use the antenna relay wire, which activates the antenna motor. Please note, if the power antenna retracts
when the radio is operating, then you cannot use the antenna relay wire to operate the remote turn-on.
Battery Connection (+12V)
This wire is usually connected directly to the positive battery terminal. Ensure that the + power supply wire is fused via an assigned fuse in
line with the + power supply wire. Please use a sufficient gauge for the installed amplifiers (min 16-25 mm). This connection must be
completed using spade plug with insulating sleeve. The ESX VE Vison amplifiers are optimized for a operating voltage of 12-16 Volts.
Maxi-Fuse (FUSE)
The mounted Maxi-Fuses protects the amplifier of short circuit and overload. If you have to replace the Fuses, only replace with a
equivalent valued Fuse. The original installed Fuse is optimized for a 4 / 2 Ohm operation and 1 Ohm operation only for musical playback.
In the 1 Ohm operation under constant load the current consumption is increased, this means you have to replace the original Fuse by a
appropriate Fuse with a higher Value (Ask your retailer).

amplifier by using appropriate RCA Cables .
• Connect the Front-/Rear-Speakers and the Subwoofer with the Speaker Outputs (+ 1CH - & + 2CH - / + 3CH - & + 4CH - and + Mono -).
• The minimum final speaker impedance should not be lower on CH1/2/3/4 than 2 Ohms and on CH5 1 Ohms per Channel.

• Turn the INPUT GAIN-Control (T5 & T7 & F8) counter clockwise until you hear some distortion.
• Then turn back the INPUT GAIN-Control (T5 & T7 & F8) slightly until you can here clean sound.
Configuration Front-Speakers Channel 1 & 2
• When you use smaller speaker systems (8.7cm - 16cm) the Input Selector should be set on HIGH PASS-Postion,because too low
frequencies can cause damages to your speakers.The cut-off frequency should be between 60Hz - 150Hz depending on the size of the
installed speakers and it is continously variable from adjustable via Highpass-Control T4 from 10 Hz up to 2500.

SPECIAL FEATURES
VE1200.5
Acoustic Phase Shift
Conventionally Systems
without Acoustic Phase Shift Acoustic Phase Shift (APS) of ESX Car Audio Systems with Acoustic Phase Shift
The ESX-VISION VE Series Amplifiers have an integrated channel separated Phaseshift Control.
By controlling the phase, perfect soundstaging is realisable.
In vehicles the listener is located in
principle outside the acoustical
center. The stereo sound seemed
to diffused and unnatural. The
sound doesn't seem to be well-
defined because the distance
between the listener and speakers
is much shorter on the left side.
With the Phase Shift Control of the
ESX VISION VE Series the stage's
acoustical center can be adjusted.
It is continously variable between
0 - 180 degrees.
By changing the Phase you can
virtually move your speakers to
the left side and the signal arrives
later, for instance on the left ear of
the listener and the acoustical
center stage is recovered. The
sound characteristics will be
played acoustical correct.
Band Pass - Function (Subsonicfilter)
By using the HIGH PASS / SUBSONIC controller you are able to adjust the lower threshold frequency of the subwoofer
signal. The upper threshold frequency is adjusted by the LOWPASS Controller. Both filters together generate an
spectrum which is called BAND PASS-SIGNAL. Now the frequency signal looks figurative like a trapeze which harmonize
very well with an subwoofer enclosure and disturbing frequencies in the lowpass-range are limited.

TROUBLE SHOOTING
System does not turn on
1. Check all fuses.
2. Check all connections.
3. Measure the +12 volt and remote turn on voltages at the amplifier terminals. If these are non existent or too low,
take voltage measurements at fuse holders, distribution blocks, the head unit’s +12 volt and remote leads to
localize the problem.
Noise problems
1. Check the speaker wiring
2. Speakers are damaged
No Signal at Channels
1. Set Balance and Fader from head unit on Zero-Position
2. Check wiring (Amplifier, Speakers)
3. Speakers are damaged
Hiss or white noise
1. Speakers are overload
2. High levels of white noise usually occurs when amplifier level controls are turned up too high.
3. Another major problem that can cause excessive hiss, is a noisy head unit - unplug the amplifier input
RCA cables, and if the hiss level reduces, the source unit is at fault.
No Stereo-Sound or Low Output
1. Check speaker wiring (- and +)
Amplifier Protect-Mode (the Display lights up red)
1. Speaker cabels are shorted
2. Inadequate cooling - relocate or remount to provide better natural airflow. Driving high power levels into low impedances -back off on the
volume control, and/or make sure you are not loading the amplifier with less than the recommended loudspeaker impedance.
3. Make sure that the battery voltage, as measured at the amplifier’s +12 volt and ground terminals, is 11 volts or more.
Electrical Interferences
The inside of an automobile is a very hostile electrical environment. The multitude of electrical systems, such as the ignition system,
alternator, fuel pumps, air conditioners to mention just a few, create radiated electrical fields, as well as noise on the +12 volt supply and
ground. Remember to isolate the problem - first unplug amplifier input RCA cables, if the noise is still present, check the speaker leads,
if not, plug the RCA’s back, and investigate the source driving the amplifier, one component at a time.
A ticking or whine that changes with engine RPM:
1. This problem could be caused by radiation pickup of RCA cables too near to a fuel pump or a distributor, for instance, - relocate cables.
2. Check that the head unit ground is connected straight to the vehicle chassis, and does not use factory wiring for ground.
3. Try to supply the head unit with a clean +12 volt supply directly from the battery +, instead of using a supply from the in dash
Wiring/fusebox. This type of noise can be more difficult to pinpoint, but is usually caused by some kind of instability, causing oscillations
in the system.
A constant whine:
1. Check all connections, especially for good grounds.
2. Make sure that no speaker leads are shorting to exposed metal on the vehicle chassis.
3. RCA cables are notorious for their problematic nature, so check that these are good, in particular the shield connections.

Caution!
In your amplifier are protection circuits integrated. Short Circuit Protection engaged: The amplifier will turn off and try to
come back immediately. The amplifier will cycle like this indefinitely, with "blips" of sound each time. If this is the case,
check your speakers and wiring for low impedance and short circuits.Thermal Protection engaged: The amplifier will turn
off and several minutes later will come back on. In this case, ensure that there is nothing blocking the normal convective
airflow of the amplifier. If the display is still lighting up red, the amplifier is damaged.
