The power supply wires (GND and +12v) and the remote wire (IN and OUT) may use
0,5mm² gauge (24awg) or bigger.
The REMOTE IN comes from player and the REMOTE OUT wired to the signal from
the amplifiers. This connection is necessary for correct operation of the system.
Input voltage: +10v to 15v.
Current Consumption: 0,35A.
The installation must be done in a local covered and ventilated place and without
vibration.
The processor has 8 buttons to configure as the owner wish.
Encoder: Correspond to 28 bands for equalization.
CH: Allow accessing the 6 channels.
ESC: Return to initial display.
