Kit
The microphone/line input gain setting is connected with the input
signal level and type of external microphone installation. The wide
gain range (0 to 39dB for a microphone input and -6dB to 24dB
for a line input) should be sufficient for most installations. Set a
value to ensure good audibility and eliminate excessive acoustic
feedback at high loudspeaker volumes with subsequent signal
saturation on the microphone/line input and thus acoustic echo
cancellation (AEC) deterioration.
Acoustic feedback filter – set automatic suppression of acoustic feedback
(typically whistling) between the intercom speaker and phone handset if located
in close proximity to the intercom. This mode is disabled by default.
Switch on automatic detection of noise or microphone noise level threshold
exceeding. Process the threshold exceeding alarm using Event.NoiseDetected
and assign it to other user actions.
