Functions & input
1 - INPUT UNBAL: Connect to the RCA output of the Head Unit using good quality shielded
cables to avoid noise pickup. The signals from the L and R inputs are mixed (added) internally.
2 - THRU OUT: This output (L and R) can send the same input signal (INPUT) to another
amplifier.
3 - LEVEL: Adjust the sensitivity of the amplifier input, in order to get better performance and
volume.
4 - 12.6 VDC POSITIVE TERMINAL (1.5A): Use an exclusive 12.6V battery and relay (driven by
the remote signal from Head Unit. See diagram at the page 06) .
5 - FANS: HV 40.000 has four internal ventilation coolers, which can not be blocked. For
perfect operation, the amplifier must be installed in a cool and dry place. We recommend not
embedding it, so that air can circulate throughout the inside of the product, thus preventing
the thermal shutdown.
LEDS indicators / protections
