Alt 3-4 MUTE/ALT 3-4 SWITCHES Every time a bell rings, an Angel gets its wings. In a similar way, every time a mute switch is pressed, that channel is muted in the main mix and appears in the alt 3-4 outputs instead. If you just want to mute the channels, then don't connect the alt 3-4 outputs to anything. Muted channels can still be soloed to audition them in the headphones and control room, and to adjust and check the channel gain levels. ALT 3-4 OUTPUTS These 1/4" TRS jacks provide a balanced line-level signal that can provide an alternate stereo mix for recording or subgrouping. Connect these outputs to the inputs of an amplifier, powered speaker, or recording device. If you want to think up some good uses for the alt 3-4 outputs then go ahead. For example, these outputs could be used to send particular channels to another zone, or you could create a sub-mix of several drum microphones. The alt 3-4 submix can then be routed to the control room and phones, by pressing the control room alt 3-4 switch, and then added to the main mix with the control room "assign to main mix" switch. The alt 3-4 output doesn't have a master level control. All the channels assigned to the alt 3-4 bus are summed together (post-fader and pan) and sent directly to the alt 3-4 out.
