PreSonus Quantum HD 8 USB-C Audio Interface

$ 999.99

The culmination of nearly 30 years of design experience, the PreSonus Quantum HD 8 is a 26x30 USB-C desktop audio interface, ideal for producers, musicians, and creators looking for high-fidelity audio and flexible connectivity options for the studio or live onstage. The HD 8 features eight high-definition MAX-HD mic preamps with +75 dB of gain, ideally suited for today's most popular microphones. Guitarists and bassists will love the front-facing instrument inputs, which were codeveloped with Fender engineers. High-performance 32-bit / 192 kHz converters with 124 dB dynamic range let you hear and capture audio with stunning clarity. Use the Quantum HD 8 to record to a Mac/Windows computer or on your iOS/Android phone or tablet.

An Auto Gain button sets the perfect gain level for your microphones and instruments, hassle-free. You also get two reamp outputs, so you can send audio from your DAW and experiment with amps and effects to sculpt your sounds. A built-in DSP monitor mixer plus loopback audio make creating monitor and streaming mixes quick and easy. Route an external A/D converter into the ADAT I/Os to record and playback up to 16 more channels of audio. You can even utilize the Universal control app to record straight to your mobile device or remotely control the Quantum HD 8. Professional recording software is included to get your productions started right away.
