Making the Most Of Your Mixer 4-2. Using Groups Group buses and faders can greatly simplify the mixing process-particularly in live situations in which changes have to be made as quickly as possible. If you have a group of channels that need to be adjusted all together while maintaining their relative levels, grouping is the way to go. Simply assign the group to a group bus, and make sure that group is also assigned to the main program bus. Then you can adjust the overall level of the group using a single group fader, rather than having to attempt to control multiple channels faders simultaneously. Group buses usually also have their own outputs, so you can send the group signal to a different external destination from the main mix. Channel faders Assigned to Group (Controlled As a Group) Group Fader A group of channels whose levels need to maintain the same relationship-a drum mix, for example-can be assigned to a group bus. Usually the group bus signal can be output independently via "Group" outputs, or it can be assigned to the main program (stereo) bus to be mixed in with the main stereo program. Once the mix between the channels assigned to the group is established via the channel faders, the overall level of the entire group can be conveniently adjusted via a single group fader.
