CONTROLS PANEL

4

B CHANNELS (Level)

It adjusts the amplifier B channels input sensitivity and sets its output level.

8

F1 SLOPE

It permits to choose LO-PASS filter slope between 12dB/Oct. (stereo) and 24dB/Oct. (mono, L+R).

5

A CHANNELS (Stereo/Mono)

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

6

B CHANNELS (Stereo/Mono)

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

7

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.

9

F1

It permits to adjust LO-PASS filter cut-off frequency between 40 Hz and 5 kHz.

10

F2

It permits to adjust 12dB/Oct. HI-PASS filter cut-off frequency between 40 Hz and 5 kHz.

11

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.
