Working with busses
Busses in the Mixer window are fully independent and may be adjusted separately. You can adjust the bus volume, change the bus meter resolution, and adjust the bus fader to eliminate clipping.
Adjusting bus volume
You can adjust a bus’s volume during project playback by dragging the fader. The fader on a stereo bus is split so that you can adjust the levels of the two stereo channels independently.
The fader can function as a trim control that adjusts the overall level of the bus, or it can adjust volume automation settings on the bus track. Click the Automation Settings button 
and verify Show Automation Controls is not selected if you want the fader to function as a trim control.
The faders are locked (ganged) so that the left and right channels of stereo files move together. Click the Lock/Unlock Fader Channels button (
) to unlock or lock the faders. You can also press Shift while dragging a fader to temporarily override a fader’s locked or unlocked state.
Tip:
If you want to adjust volume automation settings on the bus’s bus track, click the Automation Settings button
and select Show Automation Controls. For more information, see Adjusting volume or pan automation settings on page 157. The fader handle is displayed as 
in Automation mode.
You can adjust the volume of several busses simultaneously by selecting the busses and adjusting any of their faders. If you select an assignable effect along with the busses, the output fader of the assignable effect moves along with the bus volume faders.

You can select a meter resolution at which a bus displays the signal levels that are being mixed. When you change the meter resolution on this control, the other meters (assignable effects and preview) automatically change to match.
