Hi Joel,
Thanks for your enquiry and your interest in our products.
Latency figures for the Scarlett range are published here:
https://focusrite.com/scarlett-in-depth
The latency when using a D16 would depend on other parts of the system. If you're connecting the D16 directly to an ethernet port on your computer and using Dante Virtual Soundcard, your network latency will be 4ms minimum (that's the lowest option you can select with Dante Virtual Soundcard) + you'd need to factor in the driver latency of Dante Virtual Soundcard to then get sound to/from whatever software you're using (this isn't documented).
For very low latency performance, we would advise using the
RedNet PCIe card. You would connect this to a spare PCIe slot in your computer (or in a Thunderbolt chassis if you don't have a PCIe slot) - you can then either connect the D16 directly to the card and then use the spare port on the PCIe card to connect to your computer's ethernet port for control, or connect the PCIe card, D16 and the computer to a network switch.
Using the PCIe card you'll be able to select the minimum network latency value for the D16 (1ms) and take advantage of the very low latency performance of the card which will give you around 2ms additional latency to/from a DAW at 48kHz, 32 sample buffer size.
I hope this helps, if you need any further information then please let me know.
Best Regards,
Jack Cole
