PreSonus Quantum 2
22 x 24 Thunderbolt 2 Low-Latency Audio Interface

OUR PART #  QUANTUM-2


The PreSonus Quantum 2 is an expandable, ultra-high definition recording system. Taking full advantage of the high-speed Thunderbolt 2 bus and ADAT Optical I/O, the PreSonus® Quantum 2 audio/MIDI interface delivers up to 22 inputs and 24 outputs, with extremely low latency. Boasting superb audio quality; 24-bit, 192 kHz recording and playback; recallable XMAX microphone preamps; and the ability to expand your system as your needs grow, it’s a great choice for a wide variety of professional and semi-pro producers and electronic musicians.
