Page 7: Overview
IntelliGain User Manual OVERVIEW IntelliGain is a technology developed by Evertz to control the loudness of audio programs on the fly. More specifically, it calculates the perceived loudness of the input audio and modifies the audio to ensure that the long-term average loudness level is at the target level. IntelliGain works with mono, stereo and multi-channel audio per program and can handle up to 16 programs simultaneously.

To enable or disable an SNMP alarm notification, either check or un-check the defined control. The system also provides real time trap status information. If a trap is sent by the IntelliGain system, the trap status box will change state indicating the real time value for that trap. For example, if the trap status box is the colour green, then the trap has not been sent.
