Fender Quantum LT4 Audio Interface

The Fender Quantum LT 4 is a compact, bus-powered USB-C audio interface designed to make professional-quality recording, streaming, and rehearsal simple for duos, small ensembles, content creators, and growing studios. With four inputs, two outputs, transparent MAX-HD mic preamps, Fender-designed instrument inputs and powerful monitoring options, it gives you studio-grade sound and flexible routing in a portable box that fits into any setup.

At the heart of the Quantum LT 4 are two MAX-HD mic preamps delivering up to 75 dB of clean gain. That means you can use everything from delicate condensers to gain-hungry ribbon mics without battling noise, capturing vocals, acoustic instruments, podcasts and live sessions with clarity and detail. Fender-designed instrument inputs ensure your guitars and basses feel and sound right under the fingers, with a natural response that makes it easy to dial in inspiring tones straight into your DAW.

Custom low-latency drivers and high-performance 24-bit / 192 kHz converters keep your monitoring tight and responsive, so what you hear in your headphones or speakers feels immediate and accurate. Balanced TRS outputs and a powerful headphone output provide flexible monitoring options for home studios, mobile rigs and rehearsal spaces, while integrated line inputs let you hook up external preamps, synths, drum machines or mixers without fuss.

For modern creators, the Quantum LT 4 goes far beyond simple I/O. Loopback functionality lets you capture computer audio alongside your microphones and instruments, making streaming, podcasting and content creation straightforward without extra hardware. Remote integration with Fender Studio Pro and Universal Control software gives you hands-on control of your direct monitoring mixer from your desktop, tablet or phone, and Standalone Mixer Mode means you can use the LT 4 as a simple analogue-style mixer when you do not need a computer. Built-in My Fender access streamlines registration, software downloads and support, so you can get up and running quickly and stay focused on making music.

MAX-HD Mic Preamps with 75 dB Gain

The Quantum LT 4 features two MAX-HD mic preamps, each offering up to 75 dB of gain. This generous headroom and low-noise design mean you can use a wide range of microphones, including low-output dynamics and ribbons, without introducing hiss or needing extra boosters. Vocals, acoustic instruments and spoken word all benefit from a clean, detailed capture that sits easily in the mix.

Fender-Designed Instrument and Line Inputs

Dedicated Fender-designed instrument inputs are voiced for guitars, basses and other instruments, preserving feel, dynamics and tone as you plug straight in. Integrated line inputs give you additional flexibility to connect external mic preamps, synths, drum machines, mixers or other line-level devices, making the Quantum LT 4 a versatile hub for hybrid hardware and in-the-box setups.

Low-Latency Performance and Flexible Monitoring

Custom low-latency drivers and high-quality 24-bit / 192 kHz converters ensure responsive, real-time performance, so you can track with confidence and play naturally against your session. Balanced TRS outputs feed your studio monitors cleanly, while the powerful headphone output provides clear, loud monitoring for tracking, mixing or mobile work, whether you are recording solo or with a partner.

Loopback, Standalone Mixer Mode and Remote Control

Loopback functionality lets you blend computer audio with your live inputs, ideal for streaming, podcasting, lesson content and live performance broadcasts. Standalone Mixer Mode allows the Quantum LT 4 to operate as a simple analogue mixer without a computer, perfect for quick rehearsals or minimal setups. With remote control via Fender Studio Pro and Universal Control, you can adjust direct monitoring and routing from your desktop or mobile device, keeping your workflow smooth and flexible.
