QuickMedia™ Audio Extractor Crestron QM-AE
General Audio – Auto Compensation Signals
SIGNAL TYPE
AND NAME
DESCRIPTION
Digital input
<EnableAutoComp>
Enables automatic audio compensation for as long as the input is high.
High/1 (level sensitive) = Enable auto-compensation
Low/0 = Disable auto-compensation
Digital input
<MuteMicMixOut>
Mutes the AUDIO SPCH channel for as long as the input is high.
High/1 (level-sensitive) = Mute AUDIO SPCH
Low/0 = Un-mute audio
Digital output:
<MuteMicMixOut-F>
Indicates the mute status of the AUDIO SPCH channel. The feedback will remain
high for as long as the output is muted.
High/1 = Audio is muted
Low/0 = Audio is un-muted
Digital input
<MuteProgLOut>
Mutes the AUDIO L channel for as long as the input is high.
High/1 (level-sensitive) = Mute AUDIO L
Low/0 = Un-mute audio
Digital output
<MuteProgLOut-F>
Indicates the mute status of the AUDIO L channel. The feedback will remain high for
as long as the output is muted.
High/1 = Audio is muted
Low/0 = Audio is un-muted
Digital input
<MuteProgROut>
Mutes the AUDIO R channel for as long as the input is high.
High/1 (level-sensitive) = Mute AUDIO R
Low/0 = Un-mute audio
Digital output
<MuteProgROut-F>
Indicates the mute status of the AUDIO R channel. The feedback will remain high for
as long as the output is muted.
High/1 = Audio is muted
Low/0 = Audio is un-muted
Digital input
<SaveCompPreset>
This signal has NO effect if automatic audio compensation is enabled.
Saves the source gain compensation defined by <ProgComp> to the preset given
by <Preset#> when the input is held high.
High/1 (level-sensitive) = Save compensation preset
Low/0 = No preset save
Digital input
<RecallCompPreset>
This signal has NO effect if automatic audio compensation is enabled.
Recalls the source gain compensation preset given by <Preset#> when the input is
held high.
The source gain compensation is added to program volume and is applied equally to
both the AUDIO L and R channels.
High/1 (level-sensitive) = Recall compensation preset
Low/0 = No preset recall
Analog input
<MicMixVol>
Adjusts the volume level on the AUDIO SPCH channel.
Valid values range from 0% (-80dB) to 100% (+20dB).
Analog output
<MicMixVol-F>
Indicates the volume level of the AUDIO SPCH channel.
Analog inputs
<MicMixBass>
<MicMixTreble>
Adjusts the bass and treble on the AUDIO SPCH channel.
Valid values range from 0% (-15dB) to 100% (+15dB).
A value of 50% signifies a flat level corresponding to 0dB.
Analog input
<MicMixDelay>
Sets the speech delay, in milliseconds, for the AUDIO SPCH channel.
Valid analog values range from 0d (0ms) to 40d (40ms).
Out of range values will clip the speech delay to the minimum or maximum value.
Analog output
<MicMixDelay-F>
Indicates the speech delay being applied to the AUDIO SPCH channel.
