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. Every design decision during Quantum’s engineering was made with one goal in mind: speed. Quantum sports high-speed Thunderbolt 2 connectivity and a no-frills, direct-to-daw architecture, with no DSP. The result is our 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. The Quantum offers two combo mic/instrument inputs and six combo mic/line inputs, each with a digitally-controlled XMAX preamp and global +48V phantom power. You also get two ¼” TRS main outputs, eight ¼” TRS aux outputs, and two independent headphone outs with dedicated volume controls. But that’s 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. 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 our 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. Designed to be the central hub for any recording studio, the Quantum offers two main and eight auxiliary balanced line-level outputs that can be used for monitor mixing, speaker switching, or both, depending on how you work. An onboard talkback mic can be routed to any mix, and you can listen to any mix from either of two headphone amps. You also get Mute/Dim and Mono controls. With its expandability, pro features, flexible software, and abundant I/O, the Quantum fits into any recording and production environment.

...or the Lynx E22\E44 were the way to go. But, then I read a S.O.S. review on the Presonus Quantum and it made me pause to consider this product. The idea of tight integration with S1 is already a selling point, the connectivity out of the box is a lot more comprehensive versus...

New "Thunderbolt" MacBook Pro interface decision....

...thunderbolt 3 system. Without going past about $1,500, including used units, I narrowed it down to the Focusrite 8pre and Presonus Quantum. I chose the 8pre because the quantum has no direct monitoring. This would be bad in a live situation as all audio monitoring through the Quantum would be kill-switched if the computer...
