6 • "4CH/3CH/2CH" Output mode switch: selects the output configuration of the amplifier in
the following ways:
a) "4ch" configuration using 4 output channels: In this mode the amplifier can
function with a double stereo system, front and rear.
b) "3ch" configuration using three output channels: In this mode the amplifier
can function with a stereo system in Front and a "bridged" mono system in
Rear.
c) "2ch" Configuration using 2 output channels: In this mode the amplifier can
be used as a traditional 2-channel stereo amplifier with twice the normal power.
Nota: Con la configurazione "2ch", le regolazioni della sensibilità diventano indipendenti,
cioè, la sezione Front regala la sensibilità del canale Sinistro, mentre la sezione Rear regola la
sensibilità del canale Destro. In oltre se si volesse attivare il crossover è attivo solamente
quello della sezione Rear, di conseguenza il suo controllo per la regolazione della frequenza.
7 • Rear Crossover switch: select the output mode of the amplifier by activating the Low-
Pass or High-Pass filter.
a) Flat: the amplifier will reproduce the entire audio range
in relation to the signal applied at the input.
b) Low-Pass: activation of the low-pass filter, i.e.
determination of the finishing-point of the low frequencies
present at the Rear outputs.
c) High-pass: activation of the low-pass filter, i.e.
determination of the starting-point of the high frequencies
present at the Rear outputs.

Frequencies: once the high-pass or low-pass filter is inserted, the crossover
frequency can be adjusted between 30 Hz and 600 Hz in continuous mode.
9 • Adjustment of the Rear Input gain: adjusts the input sensitivity of the
amplifier, which varies from 200 mV to 4V.
10 •Rear RCA input connectors: Connect the Pre output leads of your main unit to the
amplifier input. These inputs will drive the final stages of the Rear section.
