1 - INPUT: Inputs of signals to be amplified. Connect these signals to RCA outputs of Head Unit, using
good quality shielded cables to avoid noise interference.
2 - LEVEL: It sets the amplifier input sensitivity, which allows an optimal adjustment to the output signals
levels of nearly all models of Head Units found in the market.
3 - CROSSOVER: Set the operating mode of amplifier :
20Hz
20Hz
4 - BASS BOOST: Reinforcement for the bass at 50Hz, with amplitude from 0 to 10dB (Channel 3 and 4).

SELECTOR POSITION - FULL
Audio track
Amplifies the whole audio range, responding from 20Hz
to 36KHz. This function is normally used when there is an
external crossover in the system.
36KHz
SELECTOR POSITION - HPF - (HIGH PASS)
Audio track
Amplifies signals with more intensity from the selected
frequency that varies from 80Hz to 2.2KHz (-6dB / 8ª).
This type of function is used mid-bass, mid-range
speakers or tweeters.
80Hz
2.2KHz
36KHz
SELECTOR POSITION - LPF - (LOW PASS)
Audio track
Amplifies only bass signal, the response is limited to
80Hz (-12dB/8ª), an optimal frequency cutoff for sub-
woofers.
80Hz
36KHz
ON / Protection:
LED lit: indicates that the amplifier is on.
LED flashing 2x: Power supply voltage is below 9V.
LED flashing 3x: Power supply voltage is above 16V.
LED flashing continuously, short on one of the outputs or low impedance.
