PreSonus Quantum 26x32 - audio interface 
Key Features and Benefits: 

Your expandable, ultra-high definition recording system 
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. 
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. 
Remote control with UC surface, too 
The Quantum's onboard features can also be controlled in PreSonus' free UC Surface control software, so even if you use third-party recording software, you can remotely access them. UC Surface has rapidly won accolades for an intuitive mixing interface that provides quick access to everything you need.
