Threshold: Set at -25dB. The level is adjusted only when the input signal is above -25dB. This is to
keep a natural dynamic.

Target level: We want a final target level at -10dB.

Maximum gain: Set at 10dB. Giving more gain will generate some uncomfortable level differences.

Release time: Set at 800(ms), enough time to avoid hard transition when the speaker talks again,
after a little break.

Attack time: Set at 50(ms), enough time to avoid hard transition when the speaker begin to talks,
and not too long as we want a stable level quickly (not since the middle of the sentence).

AVG time: Set at 200(ms), not too long, to detect short peaks in the speech and to be
responsive. Not too short to avoid level change too often.

You can see on the vu-meter that when the speaker talks at -18.3 dBu, the final level is around -10.5
dBu:

You can see on the vu-meter that when the speaker talks at 8 dBu, the final level is around -10.6
dBu:

This benefits both the presenter and audience. More comfortable hearing and speaking in larger
groups.
