# 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. These busses are consistent across all Axia consoles.

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 and the fader is up. The ON/OFF button has no impact to this bus. Think of the fader like a trim pot feeding the recorder. Having the fader in the off state allows you to record audio from a channel without sending that audio to air. However, if the fader is ON (and you are ON AIR) the Record bus continues to work the same way.

## Phone bus

The Phone bus is pre-On/Off and pre-fader. This means that audio will be sent to the Phone bus if the channel has Program 4 selected. The ON/OFF state of the fader, nor the fader position have any impact. The phone bus is unity gain.
