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 :
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.
Amplifies the whole audio range, responding from 9Hz
to 27KHz. This function is normally used when there is an
external crossover in the system.
SELECTOR POSITION - LPF - (LOW PASS)
SELECTOR POSITION - FULL
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.
Amplifies only bass signal, the response is limited to
90Hz (-12dB/8ª), an optimal frequency cutoff for sub-
woofers.
