The Quantum boasts a sample rate and audio resolution ranging up to 192kHz for high-definition mixing and recording capabilities. The premium-grade converters provide 120dB of dynamic range, capturing all the detail and natural harmonics, with no distortion. The high-class XMAX analog microphone preamps provide extremely high headroom, with a rich overall sound.

Expandable I/O

One of the most unique features of the Quantum interface is the ability to daisy-chain multiple units together to expand your connectivity options. You can link up to four Quantum interfaces via Thunderbolt, to gain access to up to 96 in and out connections. The BNC word clock I/O is designed to deliver tight synchronisation between digital audio devices.

Software Integration

The Quantum audio interface is easily integrated with PreSonus’ Studio One professional audio software. This opens up a new world of control, allowing you to fully integrate with the powerful software to control every aspect of your hardware. Once in Studio One, you can find full preamp control. You can also control your preamp levels wirelessly with the use of the free UC surface touch-control software.

Design & Construction

The road-rugged construction is built-to-last with its all-metal chassis and metal knobs, making it ideal for studio and live applications alike. The robust design is rack-mountable, taking up only a single unit of space in a studio rack. The front-panel gives you access to the two main mic/line inputs, and the main display gives you information on which preamp is use as well as the levels. There is also ten, 8-segment LED meters that provide precise visual monitoring for all your inputs. There is also a Talkback switch and internal Talkback microphone so you can communicate with artists while you are recording. The large volume potentiometer gives you precise control over your master levels, with dual headphone outputs located to the right hand side for private monitoring.
