5. CROSSOVER SWITCHES:
The amplifier has two selection switches with frequency cut-off function. The cut-off
adjustment should be made through the
variable crossover
controls. Each switch acts
on two channels at the same time (CH1 and CH2 / CH3 and CH4).
3. LEVEL:
Allows you to adjust the signal level
that will be sent to the speakers. Use this
control to equalize the music volume played
through the speakers.
4. VARIABLE CROSSOVER:
Allows adjustment of the crossover cut-off
range, variable from
50Hz to 2.3KHz
.
These controls operate in conjunction with the crossover switches, allowing cutoff
adjustment on the selected switch (H.P.F. or L.P.F.).
6. COOLER:
Its operation is automatic and variable, optimizing the amplifier's ventilation.
Make the installation in a ventilated place, without obstruction in the air inlets and outlets.
Audio controls
HPF:
This filter cuts off frequencies lower than the one selected in the
crossover control (50Hz to 2.3KHz).
FLAT:
It does not apply any filters, allowing reproduction of all
frequencies supported by the amplifier.
LPF:
This filter cuts off frequencies higher than the one selected in the
crossover control (50Hz to 2.3KHz). The filter has a gain of +12dB at
the selected frequencies.
