Fender QUANTUM HD2 20x24 USB-C Audio Interface

The Fender QUANTUM HD2 is a 20 x 24 USB-C audio interface built for recording vocals, instruments, digital sources, and monitor mixes from one compact desktop unit. It provides microphone, line, instrument, ADAT, S/PDIF, MIDI, headphone, monitor, and re-amp connectivity for a flexible studio hub. This makes it a practical choice for musicians and creators who need to move beyond the limited input and output options of a computer.

Two MAX-HD microphone preamps provide up to 75 dB of gain for microphones, while two front-panel instrument inputs accommodate passive guitars and basses. The front instrument inputs take priority over the corresponding rear combo inputs when connected, helping keep a guitar-focused setup straightforward. Auto Gain can set levels for microphone and guitar inputs by listening to the source during setup.

The QUANTUM HD2 supports 32-bit conversion and sample rates up to 192 kHz. Its balanced analog connections, low-noise preamp architecture, and dedicated headphone output support detailed tracking and monitoring in home, project, and production studios. DSP monitor mixing helps performers hear their sources without relying on DAW software monitoring.

Digital expansion is a central part of the design. Dual optical ADAT input and output ports support up to 16 channels at 44.1 or 48 kHz, while S/PDIF I/O adds two-channel digital connectivity. Dedicated front-panel re-amp outputs let users send previously recorded tracks to guitar amps or pedals for further processing.

The interface connects to a computer through USB-C and is compatible with recording applications that support Core Audio, WDM, or ASIO. Fender Studio Pro recording software is included as a perpetual license, and Universal Control provides hardware control and monitoring functions. As a studio grows, ADAT-capable external preamps can expand the available input count without replacing the core interface.

Key Features

• Re-Amp Outputs: Sends recorded tracks to external amps and effects pedals.

Design & Installation

The QUANTUM HD2 uses a compact black desktop enclosure with front-panel instrument inputs, re-amp outputs, channel controls, a main control knob, level metering, and a headphone connection. Rear-panel connections keep microphones, monitors, line-level equipment, digital I/O, MIDI, USB-C, and power organized behind the interface. Fender does not specify the chassis material in its published specifications.

Connect the included AC adapter and USB-C to USB-C cable before attaching microphones, powered monitors, headphones, instruments, or external digital equipment. Use balanced 1/4-inch TRS cables for monitor and line connections, XLR or TRS cables for the rear combo inputs, and TOSLINK optical cables for ADAT expansion. Register the interface to obtain Fender Studio Pro resources and download Universal Control for remote control, firmware updates, and monitor-mixer management.
