G-WARE SOFTWARE • GATING PARAMETERS

Adaptive Ambient routes this input through the adaptive ambient

portion of the gating control groups, which monitors the varying

ambient noise level in the room and changes the threshold level at

which the microphone gates on. For example, if you turn on a projector

in a conference room setting, the ambient level increases. Adaptive

Ambient increases the microphone gate threshold to prevent mics from

gating on from the projector noise. Default is On.

PA Adaptive Mode uses loudspeaker audio level on a specified output

as the new ambient level when audio is present at the power amplifier.

This prevents loudspeaker audio from gating on the mic, while still

allowing people in the room to gate on microphones as they speak. For

example, you might decide to play background music from a CD player

during a presentation. PA Adapt Mode allows you to use the output

routed from the CD player as the ambient reference to prevent the CD

player’s audio from gating on microphones. An output must be

specified as the PA Adaptive Reference for each mic in the system.

Default is Off.

Next, set the Gate Ratio, Hold Time, Off Attenuation, and Ambient

Level in the appropriate fields by using the

▲/▼ buttons or by

highlighting each field with the cursor and typing in the appropriate

number. Then select the Decay Rate and which PA Adaptive

Reference output you wish to use. Refer to the descriptions of these

features below.

Gate Ratio specifies how much louder the audio level must be above

the ambient level before the channel gates on. The gate ratio range is

from 0 to 50dB. Default is 15dB.

Hold Time determines how long the channel stays gated on after the

audio is no longer present. The hold time range is from .1 to 8.0

seconds. Default is .3 seconds.

Off Attenuation sets the amount of level reduction applied to a

channel when it is gated off. The range is from 0 to 50dB. Default is

12dB.

Ambient Level manually sets the background noise level upon which

the PSR1212 bases gating protocols. Used only if the Adaptive Ambient

feature isn’t used. The range is from -80 to 0dB. Default is Off.

Decay Rate determines how fast a channel gates off after the hold

time expires. Default is Medium.

PA Adaptive Reference determines which (speaker) output is used as

a reference for this input. If you select an output located elsewhere on
