PreSonus Quantum HD 8

TAKE THE LEAP.
The art of audio meets the science of sound.

Take a sonic leap with the Quantum HD 8. The culmination of nearly 30 years of design experience, the 26 x 30 Quantum HD 8 audio interface leverages the legacy of high-end PreSonus studio products to create stunning high-fidelity performance.

The Culmination Of 30 Years Of Innovation
The HD 8 features eight newly redesigned high-definition MAX-HD mic preamps with +75 dB of gain – making it ideally suited for today’s most popular microphones. Guitarists and bassists will love the instrument inputs, which were co-developed with Fender engineers. An Auto Gain button sets the perfect gain level for your microphones and instruments. You also get two re-amp outputs so you can send audio from your DAW to your guitar or bass amp and re-record it to experiment with different amps, pedals, and mic placements. An illuminated push encoder provides flexible control over gain level and output volume, and bright and responsive LED metering provides easy visual feedback for your outputs – making it great for self-produced recording.

High Performance Signal Flow
Our custom low-latency driver provides exceptionally low audio latencies when recording, and high-performance converters with 124 dB dynamic range let you hear and capture audio with stunning clarity and fidelity.

All-New MAX-HD Mic Preamps
The Quantum HD 8 features eight newly designed mic preamps with +75 dB of gain. Our high-definition MAX-HD preamps are transparent, low-noise, and digitally-controlled analog, making them ideally suited to today’s most popular microphones.

Co-Developed With Fender®
Built by the best ears in the business, guitarists and bassists will love the instrument inputs, co-developed with Fender engineers – industry experts who designed them specifically for guitar and bass.

Professional Recording Software Included
Leap into 12 months of Studio One+ add-ons, exclusive content, and tools, plus a perpetual license to Studio One Professional Edition.

Auto Gain
An Auto Gain button sets the perfect gain level for your microphones and instruments, so you get the perfect take every time.

Re-Amp Outputs
Re-amp audio directly from your DAW and use amps and effects to sculpt your sounds. Send audio from your DAW to your guitar or bass amp and re-record it to experiment with different amps, pedals, and mic placements.

Universal Control App
Quantum works on any mobile or desktop device, so you’re ready to record whenever inspiration strikes – whether on your phone, tablet, or in your home studio. Critical preamp functions like preamp gain, phantom power, and more can be controlled with the Quantum HD 8’s flexible front panel, or right from Studio One and the Universal Control app, so you can dial in the perfect gain staging without looking away from your recording session.

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-HDTM 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.

• 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 1⁄4-inch TRS main outputs plus 8 balanced 1⁄4-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.
