Setting the Automation Mode
You can set the automation mode of a channel strip in the Automation menu. For full
details on all automation modes, and use of the automation system, please see
Chapter 26, “
Working With Automation ,” on page 581.
Handling Mixer Inputs and Outputs
The Input slot of audio channel strips allows you to choose the physical inputs of your
audio hardware. This input (or input pair) supplies an audio signal to the track when
recording.
If Input monitoring is switched on, the signal of this audio input will be routed to the
output chosen in the Output menu, when the track is record enabled.
Note: Do not confuse the Input slot with the input format of channel strips. They are
different things entirely.
Output Routing and Sub Groups (Using Aux Channels)
The slot directly below the Input slot determines where the signal of the channel strip
will be sent. The number of available outputs is determined by the audio hardware in
use.
You can select between output channels, Binaural (see “ Using the Binaural Panner ” on
page 555), and aux channels, which can function as mixer subgroups. If the channel
strip is mono, the aux will also be mono, but can be set to stereo. If both aux and
channel strip are stereo, the entire (Mixer) signal flow will be in stereo. If surround is
chosen, and the channel strip is routed to an aux (using a Send), the aux channel is
automatically set to surround.
Hold Option while selecting the inputs or outputs of a single channel to change all
selected channel strips to the same input/output. Please note that inputs are only
changed on (selected) channel strips of the same status: mono, stereo, or surround.
This facility allows you to easily select a common input source for all (selected, stereo)
audio tracks, for example.

Tip: Double-clicking on the Output slot of any audio channel will jump to the assigned
Output channel fader, accelerating navigation in the Mixer.
