Thunderbolt 3 is backwards compatible with Thunderbolt 2 and Thunderbolt 1 devices so any Apogee Thunderbolt device will work through this adapter with no reduction in performance, latency, or sound quality.

Note: Some 3rd-party venders sell a Display Port adapter. Though the plug is the same size and shape as Thunderbolt 2 & 1, these adapters do not support Thunderbolt.
