Input Sensitivity; Protection Circuit - ESX VISION V1600A Mode D'emploi

INPUT SENSITIVITY

Turn the INPUT LEVEL controller of the amplifier to the MIN position. Then turn
the volume controller of the head unit to 80 - 90% of its full setting. Now turn
INPUT LEVEL clockwise until you hear some distortion. Then turn back INPUT
LEVEL slightly until you hear a cleaner sound.
VARIABLE BASS BOOST
By using the BASS BOOST controller you are able to increase the bass enhance-
ment from 0 to 12 dB.
ATTENTION: Use the BASS BOOST wisely!
VARIABLE LOW PASS FILTER
Set the desired crossover frequency by using the controller LOW PASS. Thus to
that only the frequencies below the chosen crossover frequency will be amplified
and the subwoofer plays more precisely and efficient.
PHASE SWITCH
The PHASE switch allows to switch the phase from 0° to 180° to match the output
signal with the vehicle's interior acoustic.

PROTECTION CIRCUIT

The PWR LED lights up green, if the amplifier is in operation.
The PRO LED lights up red, when the amplifier is overheated, or a short circuit occurs respective a too low
impedance load is connected to the speaker outputs. If this events, the internal built-in protection circuit shuts
down the amplifier automatically. The amplifier should work again properly after you have solved the problems.
Troubleshooting
• Check all connections for defects or short circuits and correct them.
• Provide sufficient cooling in the event of overheating and reduce the volume.
AUTO TURN ON
Push the AUTO TURN ON switch to ON position. The amplifier detects now a voltage rise (6 Volts) over the
connected input signal on the HI LEVEL IN when the head unit will be switched on. Hence, the amplifier will
also be turned on. As soon as the head unit will be turned off, the amplifier turns also automatically off. In this
case the turn-on connection is not needed.
NOTE: The AUTO TURN ON function usually works with 90% of all head units, because they are equipped
with "High Power"-outputs. Only with a few older and still existing head units the Auto Turn On function is not
working.
