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.
8 • Continuous adjustment of the Rear Low-Pass or High-Pass 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.
17 • Selector switch for the External Low Frequency Control: this
switch activates or deactivates the external control of the low
