PreSonus - QUANTUM AUDIO INTERFACE

Description

Taking full advantage of the high-speed Thunderbolt 2 bus and ADAT Optical I/O, the PreSonus Quantum audio/MIDI interface delivers up to 26 inputs and 32 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.

Quantum sports high-speed Thunderbolt 2 connectivity and a no-frills, direct-to-daw architecture, with no DSP. The result is PreSonus' leanest, fastest, lowest-latency interface to date. Cutting-edge 24-bit, 192 kHz converters with 120 dB of dynamic range and a surprising amount of expandability and software control options round out the package.

Expandable when you need more I/Oup to 96 in and out.

The Quantum offers two combo mic/line/instrument inputs and six combo mic/line inputs, each with a digitally-controlled XMAX preamp and individual +48V phantom power. You also get two 1/4" TRS main outputs, eight 1/4" TRS aux outputs, and two independent headphone outs with dedicated volume controls. But thats just the start. With ADAT Optical I/O and S/PDIF stereo digital I/O, you can have up to 18 digital inputs and outputs. And if you need even more I/O channels, you can stack up to four Quantum interfaces via Thunderbolt to create a monster system with up to 96 in and out. BNC word clock I/O ensures your Quantum and other digital audio devices operate in tight sync. And of course you get MIDI I/O, too.

Superior sound.

Audiophile-grade digital converters, low-jitter clocking, and recallable preamps add up to a superior recording and listening experience. The Quantum operates at up to 192 kHz for ultra-high-definition mixing and recording. High-quality converters on every input and output provide 120 dB of dynamic range to capture complex musical harmonics smoothly and naturally with no audible distortion. And the recallable XMAX Class A analog microphone preamps deliver incredibly high headroom, deep lows, smooth highs, and a rich overall sound so you'll hear every breath, transient, and detail in your recordings.

A superior choice for any production environment.

With its pro features and abundant I/O, the Quantum fits into any recording and production environment. You get two main and eight auxiliary balanced line-level outputs, as well as Mute/Dim and Mono controls. The onboard talkback mic can be routed to any mix, and you can listen to any mix from either of two independent headphone amps. All 10 analog outputs are DC coupled so they can provide control voltage to external analog equipment. Add that to Quantum's expandability, flexible software suite, blazing speed, and superb sound quality, and you have a recording system that will be the heart of your dream studio for years to come.
