ICX-AlphaCom Multi-Conference Mixer function.
Automatic Volume Control (AVC)
Automatically adjusts the volume according to background noise level.
AVC Debug
Shows current volume level on OLED display.
AVC Advanced
- AVC Lower Threshold : Threshold level for AVC starts working. Valid range: [-92..0] dBm0
- AVC Upper Threshold : Threshold level for AVC stops working. Valid range: [-92..0] dBm0
- AVC Attack Rate : How fast gain is raised when ambient noise level is increasing. Valid range:
[0..100] 1/10th db/sec ([0.1..10] dB/sec)
- AVC Decay Rate : How fast gain is reduced when ambient noise level is falling. Valid range:
[0..100] 1/10th db/sec ([0.1..10] dB/sec)
- AVC Hysteresis : Required mic signal change level before new gain is adjusted. This is applied
when there is a change in gain directions. Valid range: [1..10] db
- AVC Lockout Time : Time for successive frames after AVC lock, due to far-end active or
optional high near-end signal, before commencing AVC adjustments. A negative sign locks
AVC if signal is above upper threshold. Valid range: [1..10] db
Far-End Audio Squelch
Enables Audio Squelch on Far-End Signal (suppresses audio on low signal levels).
Squelch Threshold
Signal level below this theshold will be suppressed to silence. Range is 0dB to -92dB. Default is
-60dB.
Squelch Activate Delay
Delays time with signal below threshold level before squelch is activated. Squelch is turned off
again on first audio frame with level above threshold. This will implement a simple hysteresis
hindering too rapid on/off with a signal changing around threshold.
5.4 I/O Settings
The I/Os can either be configured as an Input or as an Output. By default all I/Os are set as Inputs.
● Select Advanced ICX-AlphaCom > I/O Settings
Fast Blink Pattern
● Set the fast blink pattern for the LEDs
Slow Blink Pattern
● Set the slow blink pattern for the LEDs
● Select either Input or Output options from the drop-down box for I/O Pins 1 to 6
