Option Description
TrimLevel
Theaudiolevelofeachincomingsourcecanbetrimmeddownandadjustedto
reducetheinputlevelofoverdrivensources,orforpersonaltastes.Inputavalue
between0and100.Optionally,thekeyboardupanddownarrowkeyscanbe
usedtoincrementanddecrementeachvalueby1.
NoiseGate
NoiseGate:Eliminatesoundsbelowasetsoundlevel,commonlyusedwith
microphonestominimizeunwantedbackgroundnoise.
• Enable/Disable:Enablesordisablesthenoisegate.
• Threshold:Setthethreshold(dB)whereaudiobelowthesetvaluewillclose
thenoisegate.Valuesarebetween-96to0.
• Attack:Settheamountoftime(ms)ittakestofullyopenthenoisegateonce
audiohasbeendetectedandisabovethethresholdvalue.Thenoisegatewill
beopenedlinearly(fadedup)acrossthetimevalueset.Valuesarebetween
10to500
• Hold:Settheminimumamountoftime(ms)thattheaudiosourceneedsto
bebelowthethresholdvalueforthenoisegatetobereleased.Valuesare
between10to500.
• Release:Sethowslowly(ms)thenoisegateisclosedonceaudiohasfallen
belowthethresholdandtheholdtimevalueisreached.Thenoisegatewillbe
closedlinearly(fadeddown)acrossthetimevalueset.Valuesarebetween10
to2000.
Auto-Gain
Auto-Gain:Automaticallyamplies(increases)orattenuates(decreases)the
audiovolumelevelofasource’sinputsignaltoachieveacomfortableaudio
listeninglevel.Thisisseparatefromtrimthatreducestheentireaudiosignal
level.
• Enable/Disable:Enablesordisablestheauto-gain.
• Threshold:Settheminimumthreshold(dB)levelforanaudiosignalthat
isneededtoactivateamplication.Thisensuresthatamplicationisnot
appliedtonoisewhenthereisnoactiveaudio.Valuesarebetween-36to-20.
• TargetLevel:Setthetargetaudiolevel(dB)thatauto-gainwilluseto
determinewhentoactivateamplicationorattenuation.Valuesarebetween
-18to-3.
• MaxAttenuation:Setsthemaximumlevelofattenuation(dB)thatcanbe
removedfromasourceaudiosignalwhenitisabovethetargetlevel.Values
arebetween11to18.
• MaxGain:Setsthemaximumlevelofamplication(dB)thatcanbeadded
toasourceaudiosignalwhenitisbelowthetargetlevelandabovethe
threshold.Valuesarebetween0to15.
