Low: Use in rooms with controlled acoustics and minimal echoes. This setting provides the most natural sound for full du
plex.
Medium: Use in typical rooms as a starting point. If you hear echo artifacts, try using the high setting.
High: Use to provide the strongest echo reduction in rooms with bad acoustics, or in situations where the echo path fre
quently changes.
Noise Reduction
Noise reduction significantly reduces the amount of noise in the signal caused by projectors, HVAC systems, or other environ
mental noise. It is a dynamic processor, which calculates the noise floor in the room and removes noise throughout the entire
spectrum with maximum transparency.
Settings
The noise reduction setting (low, medium, or high) represents the amount of reduction in dB. Use the lowest possible setting
that effectively lowers noise in the room.
Automatic Gain Control (AGC)
Automatic gain control automatically adjusts channel levels to ensure consistent volume for all talkers, in all scenarios. For qui
eter voices, it increases gain; for louder voices, it attenuates the signal.
Enable AGC on channels where the distance between the talker and the microphone may vary, or in rooms where many differ
ent people will use the conferencing system.
Automatic gain control happens post-gate (after the automixer), and will not affect when the automixer gates on or off.
Target Level (dBFS)
Use -37 dBFS as a starting point to ensure adequate headroom, and adjust if necessary. This represents the RMS (aver
age) level, which is different from setting the input fader according to peak levels to avoid clipping.
Maximum Boost ( dB)
Sets the maximum amount of gain that can be applied
Maximum Cut ( dB)
Sets the maximum attenuation that can be applied
Tip: Use the boost/cut meter to monitor the amount of gain added or subtracted from the signal. If this meter is always reach
ing the maximum boost or cut level, consider adjusting the input fader so the signal is closer to the target level.
Delay
Use delay to synchronize audio and video. When a video system introduces latency (where you hear someone speak, and
their mouth moves later), add delay to align audio and video.
Delay is measured in milliseconds. If there is a significant difference between audio and video, start by using larger intervals of
delay time (500-1000 ms). When the audio and video are slightly out of sync, use smaller intervals to fine-tune.
Compressor
Use the compressor to control the dynamic range of the selected signal.
