Functions & input
1 - INPUT : 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 - CROSSOVER
HIGH PASS: Variable adjustment from 10Hz to 90Hz, which determines the beginning of the amplifier
operating frequency.
LOW PASS: Variable adjustment from 90Hz to 10KHz, which determines the end of the amplifier
operating frequency.
5 - MONITOR: Connection to an accessory, which function is to monitor the amplifier and it is where all
information from the indicator LEDs, such as distortion (CLIP) and protection actuation (PROT), will be
displayed simultaneously.
6 - 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) .
7 - FANS: HV 20.000 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
GREEN LED (HV): Indicates high voltage presence at the power terminals.
BLUE LED (ON): Indicates powered amplifier.
YELLOW LED (CLIPPING): Indicator of clipping and protections. (See protections
below).
RED LED (PROTECTION): Indicator of protections. (See protections below).
SHORT: Red LED on.
LOW VOLTAGE (HV): Blue LED alternating with yellow.
HIGH VOLTAGE (HV): Blue LED alternating with red.
MISSING (HV): Blue LED blinking.
TEMPERATURE: Flashing yellow LED.
Voltage 12V
LOW VOLTAGE 12V: If the voltage is less than 9VDC, red LED flashes 2x.
HIGH VOLTAGE 12V: If the voltage exceeds 16VDC, red LED flashes 3x.
