Remote control
1. INPUT(S): The RCA cards are dedicated to the input of the low-level signal
2. GAIN: The GAIN rotary potentiometer allows you to adjust the level of the
input signal in the amplifier. ATTENTION: increasing the input gain does not
mean more power, but more noise. The voltage gain varies between 0.2 V to
5 V. Optimising the performance of the stereo system means applying the
maximum gains as soon as possible upstream of the stereo system, and the
minimum gains downstream.
The potentiometer must be adjusted to the source level (level of the output
line).
Begin by putting the amplifier gain to its lowest level. Gradually increase the
level (volume) of the source to ¾. Increase the level of the amplifier gain to
the maximum sound level wanted. Lower the level in the event of distortion.
3. +12V: the power supply connecter + BATT is dedicated to receiving the power
supply cable between the amplifier and the positive (+) battery terminal.
4. GND: the GND (ground) power supply connector is dedicated to receiving the negative (-) cable power supply cable
providing the connection between the amplifier and the vehicle chassis.
5. REM: the REM connector links the amplifier and the source (car radio) using a REM or REMOTE car radio output.
This makes it possible to turn on the amplifier as soon as the source (car radio) is switched on. This connecter is not
necessary if 10 inputs are used.
6. SPEAKERS: the SPEAKER connectors link the amplifier and the loudspeakers. It is ESSENTIAL to comply with the
polarities (+ amplifier + filter or + speaker/- amplifier - filter or speaker).
7. FUSES: the FUSES connecter is dedicated to receiving the amplifier fuses. If they are replaced, make sure that the
amperage corresponds (2 x 15A).
8. LEDs: the LEDs make it possible to check that the amplifier is working properly. There is one on the front of the
subwoofer and the other is on the remote control unit.
A steady LED means that the product is operating normally.
No LED or a flickering LED means that the product is not working properly based on the default codes given in Figure
13.
9. REMOTE CONTROL:
NOTE: DO NOT CONFUSE REMOTE AND REMOTE CONTROL. The REMOTE CONTROL output is dedicated to
connection of the remote control unit supplied. This accessory makes it possible to adjust the amplifier gain remotely
and access the DSP tuning through the computer software interface.
10. HIGH-LEVEL INPUT(S) This connecter is dedicated to high-level inputs (wiring on the amplified outputs of a car
radio with no RCAs).
11. PREAMP OUT: The RCA replicating the input, this output does not provide DSP adjustments; it is intended for the
addition of an amplified system supplementing the DSA 500 RT.
12. REAL-TIME CONTROL: USB connection for software programming.
13. SUBWOOFER GAIN POTENTIOMETER: makes it possible to adjust the subwoofer gain from -9dB to +9dB around
the general amplifier GAIN. (This potentiometer only affects the subwoofer volume).
