Line Monitoring
ON: Line monitoring enabled
A 21-kHz pilot tone signal (not hearable) will be delivered to the
outputs continuously to detect short circuit or ground fault events on the audio outputs lines. Its
amplitude is between 6V..10Vrms on the outputs, depending on the load. (No load = 10Vrms,
@17Ω is about 6V
) At over circa 70Vrms output level (in case of alarm) it will be de-activated
automatically to ensure the maximum audio power and to avoid false clipping issues. At under circa
60Vrms output level, it will be re-activated automatically.
OFF: Line monitoring disabled
VOX
ON: Voice Operated Circuit enabled.
This function removes the “hum and noisy” silences from the
audio path. This is the default setting.
OFF: Voice Operated Circuit disabled.
Noise reduction is disabled.
2.8. Control In/Out (optional)
The RJ45 connector is for remote control and monitoring (without any network capabilities)
