Key Features

HIGH PERFORMANCE SIGNAL FLOW. Our custom low-latency driver provides exceptionally low audio latencies when recording, and high-performance converters complete the front end to ensure that you sound your best throughout your entire signal chain.

ALL-NEW MAX-HD MIC PREAMPS. The Quantum HD 2 features two 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 input co-developed with Fender engineers – industry experts who designed them specifically for guitar and bass.

PRO RECORDING SOFTWARE LICENSE INCLUDED: Studio One Pro perpetual license.

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 2’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.
