CONTROLS AND INDICATORS
6 • Continuous adjustment of the Pre-output 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.
7 • Pre-output Crossover selector: selects the Pre-output mode, activating the Low-Pass or
High-Pass filter.
a) Flat: a signal will be present on the Pre-output, in
relation to the signal applied at the input of the amplifier.
b) Low-Pass: activation of the low-pass filter, i.e.
determination of the finishing-point of the low frequencies
present at the Pre-output Outputs.
c) High-pass: activation of the low-pass filter, i.e.
determination of the starting-point of the high frequencies
present at the Pre-output Outputs.
8 • Pre-output Output Connector: it is possible to connect a supplementary amplifier for use
according to a previously selected mode.
15 • Selector switch for the External Low Frequency Control: this
switch activates or deactivates the external control of the low
frequencies.
16 • Port for EBC connection: By means of the appropriate EBC control
it is possible to act on the level of the
low frequencies between 0dB and -
40dB.
