Polycom RMX 1500/2000/4000 Administrator's Guide
When there is a change of speaker in a Continuous Presence conference, the transition is set by
default to fade in the current speaker while fading out the previous speaker.
To make this transition visually pleasant, fading in the current speaker while fading out the previous
speaker is done over a period of 500 milliseconds.
The Fade In / Fade Out feature can be disabled by adding a new flag to the System Configuration.
The Value of the new flag must be: FADE_IN_FADE_OUT=NO.
Fade In / Fade Out is not supported with MPMx cards.
For more information about System Flags, see the RMX 1500/2000/4000 Administrator's Guide,
Chapter 19, "System Configuration" on page 19-4.
