We are using the Aux mixes 1-16 on the StudioLive 64s to send Aviom channels to the stage for our band and each source can still be heard even if the channel is muted on the board. We have tried to change the Aux Mix setting from Pre1 to Pre2 and even Post, but they can still hear everything if the channel is muted on the main mix. Any way to get around this? If a channel is muted on the main mix, we do not want the Aux mixes to still get the audio for that channel
