The Fender Quantum LT 4 is the mid-range model in the company's LT series of USB audio interfaces, which are designed for spontaneous recording and the simultaneous capture of multiple signals. It features two MAX-HD microphone preamps developed specifically for the series, each offering up to 75dB of gain, while 48V phantom power allows a wide range of microphones to be connected directly without the need for an additional preamp or booster. Combined with optimised drivers and clean converters, the interface is designed to deliver professional-quality recordings with virtually no latency and minimal setup. The hardware models in the series were the first new interfaces introduced following Fender's acquisition of PreSonus, while the former PreSonus Studio One DAW was subsequently rebranded as Fender Studio Pro.

Dynamic, natural, and present
This 4 x 2 USB audio interface features a USB-C port, USB 2.0 connectivity, and a headphone output for flexible monitoring, while the two front-panel instrument inputs are optimised for guitar, bass, and other instruments. The rear panel provides two mic/line combo inputs for XLR and jack connections, along with two balanced TRS outputs, while the loopback function is useful for streaming and content creation such as podcasting. For mixing and computer-free operation, the standalone "Mixer Mode" allows the Fender Quantum LT 4 to work very much like an analogue mixer, with a frequency response of 20Hz to 20kHz and a dynamic range of 116dB. Conversion is supported at up to 24-bit/192kHz, with THD+N as low as 0.001% and a maximum input level of +14dBu.

The perfect entry-level choice
The Fender Quantum LT 4 is a compact, thoughtfully designed recording solution that makes a straightforward introduction to home recording while also lending itself well to spontaneous mobile sessions. It combines solid recording performance with a simple workflow, supported by two MAX-HD microphone preamps that provide enough gain for demanding microphones, including ribbon models, without requiring separate preamps. Integration with Universal Control and Fender Studio Pro adds useful flexibility, particularly through remote control of the mix settings, while Standalone Mixer Mode allows the interface to operate independently as an analogue mixer for applications such as live performances, teaching, rehearsals, and mobile setups. Its bus-powered design also keeps cabling to a minimum, which is especially convenient when working away from the studio.

About Fender
Fender is without doubt one of the most legendary guitar and amplifier manufacturers of all time. The company was founded in 1946 by its namesake Leo Fender († 1991), whose innovative ideas brought a breath of fresh air into the musical world. His Telecaster, Stratocaster, Precision Bass, and Jazz Bass are not only classics – they also continue to shape the styles of musicians in countless genres to this day. Timeless Fender amplifier models such as the Bassman, Twin, Deluxe, and Princeton also enjoy a stellar reputation. Besides maintaining its classic product portfolio, however, the company is also constantly developing new products that make Fender a driving force in today's music industry.
Tailored to individual requirements
The Fender Quantum LT 4 is part of a broader range of audio interfaces, giving users the flexibility to choose a model that fits their requirements and existing setup. Alongside the compact Fender Quantum LT 2 with two inputs and two outputs, the range includes the Quantum LT 4 (shown here) with four inputs and two outputs, while the flagship Quantum LT 16 provides 16 inputs and eight outputs. The largest model is also available in a 19" rack-mountable format and adds MIDI input and output connections for more extensive studio setups.
In the spotlight
Fender Studio Pro
The Fender Quantum LT 4 is controlled via Fender Studio Pro, the company's all-in-one music production software. Essentially an updated version of PreSonus Studio One Pro, it retains the core technology of its predecessor while introducing a revised interface and a range of new features. These include a more streamlined workflow, new overview functions, and AI-powered audio-to-MIDI capabilities, while effects from Mustang Native and Rumble Native further expand the available sonic palette. Existing content, plugins, and Studio One Pro projects remain compatible, allowing users to carry their previous work into the updated environment, and the LT 4 includes a six-month trial of the software.
