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

A CHANNELS (Stereo/Mono)

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

5

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.

7

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.
