Channel G Surround
Channel G Surround is a Compressor/Limiter optimized for 5.1 channels using 4 compressors sets – LR, C, LsRs, and LFE.

These compressor sets can key from any combination of the LR, C, LsRs, and LFE channels. Individual compressor controls can be linked across various surround channels, and the LFE channel includes an optional low pass filter.

The Channel G Compact user interface seamlessly integrates with the Avid S1, S4, and S6 control surfaces, the D-Control and D-Command legacy control surfaces, as well as the S6L live sound consoles.

Channel Ducking
Giving different channels emphasis at different times enhances the listening experience and allows an otherwise crowded mix some breathing room. When choosing the key input for a given Compressor/Limiter set, selecting the channel sets other than what the Compressor/Limiter is operating on, causes that compressor/limiter to compress its channel when the others combine to exceed the level of that channel’s threshold. Such an effect, often referred to as ducking, is a great way to almost ‘ride the gain’ of tracks without the countless hours of editing track fader automation.
Control Linking
Extensive control linking is available in the G Surround Compressor (5.1). Each compressor (LR, C, LsRs, LFE) can act as a master, and selected compressors can link (relatively) to the master band. A compressor is made the master by pressing the ‘M’ button located under each compressor page selector. Pressing the ‘L’ button on any of the other compressors will enable those compressors to slave (or link) to the master compressor.
Control Matrix
Each Channel set is accessible from the page control located in the ‘control matrix’ at the right lower half of the user interface. Selecting one of the large green buttons sets the controls above it to operate the Compressor/Limiter for the LR, C, LsRs, or LFE channel sets. The multi-channel key input for each dynamics set is shown in the blue LCDs just below the standard 6 Compressor/Limiter controls.
