  • 26x32 I/O Digital Audio Interface
  • Low-Latency Recording
  • 24-Bit/192 kHz,120 dB of Dynamic Range
  • 8 x XLR / 1/4" Inputs with XMAX Preamps
  • 8 x 1/4" Balanced Line Outputs with CV


The Quantum from PreSonus is a low-latency audio interface which, via analogue, ADAT, and S/PDIF connections, gives you up to 26 inputs and up to 32 outputs. The unit’s convertors allow for low-latency recording, as well as dynamic ranges greater than 120 dB on both the ADC (analogue to digital) and DAC (digital to analogue) side. Furthermore, the Quantum captures audio at 24-bit resolutions, achieving sample rates up to 192 kHz.

For analogue I/O, the Quantum provides a sizeable complement of eight inputs and 10 outputs, including two combination 1/4" / XLR jacks for instruments, mic-level, and line-level signals, as well as six combination XLR/TRS jacks for balanced audio (mic and line); your output section, on the other hand, offers eight 1/4" TRS terminations, two balanced 1/4” monitor connection points, and two headphone jacks with dedicated volume controls. The inputs provided are PreSonus’s recallable XMAX pres. Every analogue output is DC-coupled, and the line outputs can also deliver control voltages for analogue gear.

Onto the digital I/O, wherein you’ll find two banks of optical ADAT I/O, as well as S/PDIF connections, bringing the grand total of ins and outs to 26x32. You’ll find that the unit sports BNC wordclock connections, thus facilitating wordclock sync with other pieces of gear in your studio, such as a master clock. 5-pin DIN MIDI I/O lets you connect your control or provide MIDI signal to apposite units. 10 eight-segment LED metres are provided, as are mute, dim, and mono functions—quite useful during mixing. A talkback system and internal talkback mic will allow you to communicate with artists over their headphones while they record. Thunderbolt 2 ports offer connections to your host computer, and with two of them on hand, you can chain multiple units (up to four, if you so choose). Included with the Quantum is a version of PreSonus’s very own DAW, Studio One Artist.
