PreSonus Quantum 2626 26x26 Thunderbolt 3 Audio Interface

Every design decision with the Quantum 2626 audio interface from PreSonus was to engineer it for blazing-fast speed and pristine audio quality. The Quantum-series proprietary Thunderbolt driver was written from the ground up to deliver ultra-low-latency performance while maximizing efficiency. High-quality converters on every input and output provide 115 dB of dynamic range to capture complex musical harmonics smoothly and naturally with no audible distortion.

Audiophile-grade digital converters, low-jitter clocking, and transparent preamps add up to a superior recording and listening experience. Record and monitor from your favorite DAW with any plug-in engaged. Insert your favorite outboard analog gear with ease. Impressive speed combined with stunning sound quality means that the Quantum Thunderbolt audio interface is an ideal recording solution for any size of studio.
