The Program 4, Record, and Phone busses

Scope

The Program 4 bus is a special bus that also includes the phone and record busses, depending on the state of the On/Off buttons, and the position of the fader.

All three of these functions are triggered by placing a fader channel into Program 4.

Program 4 bus

The Program 4 bus is just like the other 3 program busses. This means that when a channel is placed in Program 4, audio will be sent to that bus when the channel is turned On and the fader is Up.

In other words, the Program 4 bus is post On/Off (channel is turned On), and post fader (fader needs to be up).

Record bus

The Record bus is pre-On/Off, but post fader. This means audio will be sent to the Record bus if the channel has Program 4 selected, the channel is Off, and the fader is up. Think of the fader like a trim pot feeding the recorder. Because the fader is Off, this allows you to record audio from a channel without sending that audio to air.

Phone bus

The Phone bus is pre-On/Off and pre-fader. This means that audio will be send to the Phone bus if the channel has Program 4 selected, the channel is Off, and the fader is down. The phone bus is unity gain, and pre-fader.
