CONTROLS PANEL
F1
It permits to adjust LO-PASS filter cut-off
frequency between 40 Hz and 5 kHz.
9
F2
It permits to adjust 12dB/Oct. HI-PASS
filter cut-off frequency between 40 Hz and
5 kHz.
10
F1 SLOPE
It permits to choose LO-PASS filter slope
between 12dB/Oct. (stereo) and 24dB/Oct.
(mono, L+R).
8
B CHANNELS (Level)
It adjusts the amplifier B channels input
sensitivity and sets its output level.
4
B CHANNELS (Stereo/Mono)
It permits to configure B channels outputs
signal as stereo or mono.
6

It permits to configure A channels outputs
signal as stereo or mono

SUBSONIC
It permits to eliminate subsonic
frequencies; these sounds cannot be heard
by human ears but cause useless and
damaging stress to amplifier and speakers.
Subsonic filter can be bypassed (BYPASS)
and it is pre-set at 20 Hz. Its cut-off
frequency can be adjusted between 16
and 32 Hz through 4 Hz steps; this occurs
by replacing the special resistors located
into a socket which can be reached
through the setting panel in the amplifier
bottom.

SAFETY (red LED)
It indicates that the amplifier protection
circuits are on. In order for the amplifier to
work again, you need to switch the
system off and then on after 10 seconds
at least. We recommend to check all
connections before switching the
amplifier on again.
If LED stays on, please contact Audison
authorised after sale centres.
