3 - CROSSOVER:
Set the operating mode of amplifier :
2 - GAIN:
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.
The MIN position of this control allows to receive up to 4V RMS signals into RCA inputs.
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.
SELECTOR POSITION - FULL
Amplifies the whole audio range, responding from 8Hz
to 20KHz. This function is normally used when there is an
external crossover in the system.
SELECTOR POSITION - HPF - (HIGH PASS)
Amplifies signals with more intensity above 90Hz. This
type of function is used mid-bass, mid-range speakers or
tweeters.
SELECTOR POSITION - LPF - (LOW PASS)
Amplifies only bass signal, the response is limited to
90Hz (-12dB/8ª), an optimal frequency cutoff for sub-
woofers.

Head Unit
4 - HIGH LEVEL INPUT:
Input for high level / low impedance signals (from the speaker output
of the head unit), it features function auto turn on by the input signal, compatible with head
units with speaker diagnosis (A.S.S. Advanced Speaker Simulation OEM HU) so it eliminates
the need of the REMOTE IN wire from the power connector when using this input.
Note:
The system is designed for use in virtually all head units on the market. However, on some
you may not get the auto turn on function due to the type of audio output circuit. In this case, use
the REMOTE wire.
