4 - CROSSOVER:
Set the operating mode of amplifier :
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 - HIGH PASS - (HPF):
Variable adjustment from 80Hz to 2.2KHz, which determines the
beginning of the amplifier operating frequency, when select HPF mode.

SELECTOR POSITION - HPF - (HIGH PASS)
Amplifies the whole audio range, responding from
8Hz to 45KHz. This function is normally used when
there is an external crossover in the system.
SELECTOR POSITION - FULL
SELECTOR POSITION - LPF - (LOW PASS)
Amplifies signals with more intensity from the
selected frequency ranging from 80Hz to 2.2KHz
(-6dB / Octave). This type of function is used for
playback of mid-bass, mid-range speakers, horns or
tweeters.
Amplifies only bass signal, the response is limited to
80Hz (-12dB/8ª), an optimal frequency cutoff for sub-
woofers.
