Inactive Outputs and DSP Resources

Making a track output inactive silences the output, while retaining all automation and playlist data. Inactive outputs do not consume resources for TDM mixer connections, but any assigned plug-ins on the track continue to use their required DSP resources. Host-based AAX and RTAS plug-ins require CPU resources. DSP‑based AAX and TDM plug-ins use the DSP available on Avid HDX and Pro Tools|HD cards.

You can free up DSP of an unused plug-in by making its track inactive, or by making just the plug-in inactive.

See Active and Inactive Items, and Making Inserts Inactive for more information.
