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.

It permits to adjust the subwoofer 24dB/Oct. LO-PASS filter cut-off frequency between 40 Hz and 150 Hz.

It permits to adjust the Rear system 12dB/Oct. HI-PASS filter cut-off frequency between 40 Hz and 150 Hz. It works only in Front-Rear configuration.

SUB (Level)

It adjusts the amplifier Sub channel input sensitivity and sets its output level.

It permits to adjust the woofer 12dB/Oct. LO-PASS filter and the Mid-Tweeter 12dB/Oct. HI-PASS filter crossover frequencies between 150 Hz and 5 kHz. It works only in Multichannel configuration.

REAR M-TW (Level)

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

In multichannel configuration, the adjustment concerns the channels for the high frequencies HI-PASS filter (M-Tw).

FRONT WF (Level)

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

In multichannel configuration, the adjustment concerns the channels for the woofer BAND-PASS filter (Wf ).

It permits to adjust the 12dB/Oct. HI-PASS filter cut-off frequency between 40 and 150 Hz; this filter is for woofer in Multichannel configurations and for Front system in Front-Rear configurations.

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.
