Mixing : Basic Mixing : Delay Compensation : Determining Your Hardware’s Insert Delay

Determining Your Hardware’s Insert Delay
Refer to the documentation for your external hardware to see if it identifies the hardware latency, or use the following procedure in Pro Tools to determine the latency for hardware inserts.
To determine your hardware’s insert delay:
1 Ensure that Automatic Delay Compensation is enabled (Options > Delay Compensation).
2 Change your session’s Main Time Scale to Min:Sec.
3 Create two tracks.
4 Place a short tone (or other sound with a definitive beginning) on track 1.
5 Insert the HW insert on track 1.
6 Ensure that only the dry signal is being passed through the device.
7 Bus the output of track 1 to the input of track 2.
8 Record enable track 2 and press Record Enable and Play in the Transport window to play back the audio in track 1 and record it to track 2.
9 After recording, zoom in and measure the difference between where the audio starts in track 1 and track 2. The difference is the value you would enter as your hardware’s insert delay offset.
