Controls and indicators

The SELECT button toggles through the list of all the parameters, the < and > buttons edit a currently selected entry.

• AUDIO set of parameters:
  • DIF LEVEL: audio level difference, 2dB~12dB with 0.5dB steps or level monitoring OFF
  • THR: silence threshold, –30dB to - 60dB or silence monitoring OFF
• TIME: delay time (0,1s to 99,9s) before the changeover on any of the faults being monitored
• RECOVERY: delay time (1s to 999s) before the changeback on any of the conditions under monitoring, OFF disables automatic changeback

Please, note! To avoid an erroneous changeback the "RECOVERY" delay should be longer than the longest changeover delay.

The STATUS indicators display:

• operation mode (A, B or AUTO)
• AUDIO set of parameters (main and standby inputs):
  • DIF.LEVEL:
    • lit in green: level difference is within the preset limit (2~12dB)
    • lit in red: level difference is outside of the preset limit
    • not lit: level monitoring is OFF

Please, note! In case of simultaneous silence/underlevel condition on A and B inputs - an unrecoverable fault - both LEDs are lit in red.
