Professional Sound Quality

PreSonus are renown for their superior sound on audio interfaces. The ultra high definition sound is down to the audio interface operating at 192kHz to provide you with high-quality and makes sure your mixing and recording is always top quality. The Quantum 2 combines low-jitter clocking and re-callable XMAX Class A analog microphone preamps to deliver a recording and listening experience like no other. Including incredibly high headroom, with a wide frequency range, the Quantum 2 delivers a complete rich sound enabling you to hear every nuance and detail of your recordings.

High Speed

The Quantum 2 Thunderbolt Audio Interface delivers exceptional speed and high-quality results. With its high speed Thunderbolt 2 connectivity, and the ability to record straight to DAW, removing any need for DSP, the Quantum 2 is PreSonus' fastest, lowest latency audio interface.

Flexible and Expandable

The PreSonus Quantum 2 features multiple connections, including 2 combo mic/instrument inputs and 2 combo mic/line inputs that deliver superior sounds for your microphones and instruments. Each of these connections features a digitally-controlled XMAX preamp with +48 phantom power for connecting in condenser microphones. There are also 4 balanced live-level outputs for connections to your monitors and/or headphones, all of which are DC coupled enabling them to provide control voltage to external analog equipment, and 2 MIDI ports for connecting up your external MIDI devices such as a keyboard. Additionally, if you are looking to expand, the Quantum 2 Audio Interface allows you to daisy chain up to 4 Quantum 2 interfaces via Thunderbolt to create up to 80 ins and outs. The BNC word clock I/O is designed to ensure the Quantum 2 interfaces and any other digital audio devices are tightly integrated with one another.

PreSonus Studio One Integration

The Quantum 2 is tightly integrated with Presonus' Studio One software, opening up a whole new world of control. The Studio One Artist software provides users with a complete recording package to get you set up and ready to record and mix. Additionally, you can also control wirelessly using the Launch Studio One Remote on a iPad.
