The PreSonus Quantum HD 8 is a high-performance USB-C audio interface that features high-quality 32-bit recording along extensive expandability options. The Quantum HD 8's cutting-edge 32-bit converters provide a whopping 124dB of dynamic range, while also supporting sample rates up to 192kHz. Paired with eight of the new Presonus HD-MAX preamps, you're given plenty of crisp and clear gain to record any and all audio sources. You can even leverage the onboard Auto Gain function to make setup faster and easier.
The Quantum HD 8 also benefits from Presonus new ownership. In collaboration with Fender engineers, the instrument inputs are optimized to sound incredible with your guitar or bass. Furthermore, two re-amp outputs are available to send audio through amps or guitar pedals, allowing you to get creative with hardware and effects processing. On the topic of hardware, you can even more channels via ADAT optical connections—16 in fact, at up to 48kHz sampling rates via the two I/O ports.
Controlling the Quantum HD 8's settings from the front panel is easy, but you've also got remote control options, too! Presonus has the Universal Control App available, while integration with their Studio One DAW allows you to tweak hardware settings right from your session. Speaking of Studio One, you can also benefit from a perpetual Studio One Professional license with the purchase of a Quantum HD 8, plus 12 months of Studio One+ to get you additional content and tools. Perfect for any studio that might need to record multiple tracks at once (and then some), the Presonus Quantum HD 8 is ready to lend a hand in your sessions.
