Give your project studio room to grow with the professional-grade Quantum HD 8 26 x 30, 32-bit / 192 kHz USB-C Audio Interface. Featuring eight redesigned MAX-HD mic preamps with +75 dB of gain, it's perfectly tailored for today's most popular microphones. Guitarists and bassists will appreciate the two instrument inputs, co-developed with Fender engineers. An Auto Gain button ensures optimal levels for your recordings, while two re-amp outputs invite experimentation with different amps, pedals, and mic placements after the initial tracks have been recorded. An integrated custom driver guarantees minimal audio latency during recording, while the high-performance converters deliver stunning clarity and fidelity from tip to tail. With a 124 dB dynamic range, you'll capture everything from a whisper to a scream with the depth and realism it deserves. Control your Quantum HD 2 effortlessly from Studio One or the Universal Control app, adjusting preamp gain, toggling phantom power, and more without interrupting your recording session. Plus, enjoy 12 months of Studio One+ add-ons and exclusive content. With speaker-switching capabilities and a full-color high-resolution screen, the Quantum HD 2 offers unparalleled flexibility and control for your recording needs.

PreSonus Quantum HD8 Features:

• 26 x 30, 32-bit / 192 kHz USB-C Audio Interface
• High-performance converters with 124 dB dynamic range let you hear and capture audio with stunning clarity and fidelity
• A custom low-latency driver provides exceptionally low audio latencies when recording
• Eight all-new, next-generation PreSonus MAX-HD preamps provide transparency and accuracy across the frequency range with +75 dB of gain to maximize the performance of today’s most popular microphones for modern recording and broadcast.
• Discreet phantom power means consistent, full power for microphones that require it, so you’ll get the most from your high-performance studio microphones.
• 2 Re-amp outputs let you send audio from your DAW to your favorite outboard gear and record it again so you can experiment with different amps, pedals, and mic placement to get the exact sound you want without cutting multiple takes.
• Control your Quantum HD 8 right from Studio One and the Universal Control app, in addition to hardware, so you can adjust preamp gain, toggle phantom power, channel settings, and more without looking away from your recording session. Perfect for dialing in optimal gain staging.
• Universal Control and your Quantum HD 8 also enable speaker switching—easily check your mixes on two different speaker sets for accuracy.
• A full-color, high-resolution screen lets you keep an eye on your input and output meters while an illuminated push encoder provides fast, intuitive control over channel and output settings.
• 16 channels of ADAT Optical input (up to 48 kHz) plus stereo S/PDIF I/O make connecting your digital gear fast and easy
• ADAT standalone mode adds 8 pres and 10 outputs to your existing audio interface – so you can connect up to two additional Quantum HD 8s through ADAT for a total of 24 mic pres at sample rates up to 48 kHz.
• 2 balanced ¼-inch TRS main outputs plus 8 balanced ¼-inch TRS line outputs and 2 high-power headphone outputs give you flexible monitoring, while built-in speaker switching allows you to check your mix on multiple sets of studio monitors.
• DSP monitor mixer plus loopback audio make creating monitor and streaming mixes quick and easy.
