PreSonus Quantum 2, 22x24 Thunderbolt 2 Ultra Low Latency Interface

Description

I bought two Quantum 2 interfaces to use paired together, but only ended needing to use one at a time. So selling the extra that was never used. These are among the lowest latency interfaces available!
PreSonus does not include Thunderbolt cables with their Quantum series, so you will need to have your own Thunderbolt 2 cables and/or adapters. It works with all generations of Thunderbolt.
This is a SUPERB interface and I recommend it highly.
