Ducking & AutoMute
AutoMute Threshold
The AutoMute Threshold control shows
the device current setting and allows
the setting to be adjusted between 0
and 100%. Factory default is 0%.
(Technically, this is ‘OFF’ since the
audio level cannot go below 0%)
When the 3.5mm LINE IN audio level is below the AutoMute Threshold value, the
LINE IN audio will be muted after the AutoMute Delay time has elapsed.
The LINE IN audio will be immediately un-muted with audio level is above the
AutoMute Threshold value.
Ducking Threshold
The Ducking Threshold control shows the device current setting and allows the
setting to be adjusted between 0 and 100%. Factory default is 100%. (Technically,
this is ‘OFF’ since 100% cannot be exceeded)
If the 3.5mm LINE IN audio level exceeds this amount, the HDMI/ARC volume will
be reduced by the given ‘Ratio’.
Ratio
The Ratio control shows the device Ducking Threshold ratio. This is the percentage
the HDMI/ARC volume is reduced when the Ducking Threshold is exceeded.
Factory Default is 50% (ie… cut the HDMI volume in half)
PageSense
Threshold
The Threshold control shows the device Paging Sensor voltage threshold. Factory
default is 100%. (Technically, this is ‘OFF’ since 100% cannot be exceeded)
If the Paging Sensor input voltage exceeds this amount, the audio output will be
muted.
When the input voltage goes below this amount, the audio output will be un-muted.
Overcurrent
Threshold
The Threshold control shows the device Overcurrent voltage threshold. Factory
default is ~30%.
Example
When the Ducking Threshold is exceeded, whatever volume level the HDMI/ARC is
currently set for will be reduced by the ‘Ratio’.
If the volume level is currently set to 75% and the ‘Ratio’ is set for 50%, when the Ducking
is in effect, the output volume level will be set for 75% * 50% = 37.5%.
