50.5Loudspeaker supervision

Proceed as follows to diagnose the loudspeaker supervision:

1 Check the supervision of all loudspeakers and loudspeaker lines by reducing the levels of the communication (Communication) or the pilot tone (Pilot tone).

2Check for fault events with reduced level. If no relevant faults are present, then resume normal operation by restarting the network controller.

Note

This diagnose option only works for amplifiers with multiple loudspeaker line supervision boards installed and configured (see section 12).

Note

Checking takes up to 100 s for systems with loudspeaker lines in the Immediate fault report mode (see section 44.4). In the Recheck before fault reporting mode or with individual loudspeaker supervision, checking may take up to 300 s.

50.6 Device information

The Device information page in the Diagnose section (see figure 50.2) can be used to check the hardware version of the connected devices, their firmware version and other relevant information. Because some system functions are only supported for devices using relatively new hardware and firmware, this page may be a convenient source of information. For units with a front panel LCD, most of this information is also availbale from the LCD, but for units without LCD this page provides the relevant information.
