TASCAM US-4X4HR 4-in/4-out USB Audio Interface 24-bit/192kHz MIDI IN/OUT Loopback Two Headphones

Description

The US-4x4HR is a 4-in/4-out high-resolution USB audio/MIDI interface designed for content creators and musicians who need clean, low-noise multichannel I/O. It combines four XLR/TRS combo inputs, Ultra HDDA mic preamps, and support for 24-bit/192kHz recording to preserve audio fidelity. The unit also includes MIDI IN/OUT and two headphone outputs for flexible monitoring.

Key features include four XLR/TRS combo inputs with +48V phantom power, instrument inputs on channels 1-2, balanced TRS line outputs 1-2 and 3-4, and a loopback function for streaming applications. The improved TASCAM driver offers selectable buffer sizes down to 4 samples on Windows for low-latency performance. Zero-latency direct monitoring ensures performers hear themselves in time while tracking.

Performance is focused on accurate reproduction and low noise. The interface supports sample rates up to 192 kHz and 24-bit quantization, and the Ultra HDDA mic preamps provide a transparent sound with mic amp EIN of -128 dBu or lower. Measured THD+N figures are in the low 0.001% range and S/N ratios reach around 110 dB depending on I/O, reflecting the unit’s low-noise analog design.

Connectivity covers modern production workflows – a USB Type-C port provides USB 2.0 High Speed connectivity and USB bus power for convenient laptop use, and an included AC adapter is available for systems that need external power. Standard DIN 5-pin MIDI IN/OUT, balanced TRS outputs, dual headphone jacks, and compatibility with Core Audio, ASIO, WDM, and Core MIDI make integration straightforward. The interface also supports iOS devices via a Camera Adapter and works with popular streaming software including OBS using the loopback function.

Typical applications include podcasting and live streaming where loopback and OBS support are required, multitrack home recording with multiple mics and instruments, and mobile production where USB bus power is beneficial. The configuration supports simultaneous vocal and guitar tracking, overdubs, and stereo/master outputs to an external mixer or monitor controller. Bundled DAW and plug-in software accelerate setup for new users.

Installation and operation are simple thanks to front-panel gain controls, clear connectors, and a compact chassis. The unit measures 296 x 65 x 160 mm and weighs approximately 3.53 lb, making it easy to place in a desktop rig or mobile case. Overall, the US-4x4HR delivers professional audio features and reliable performance in a compact, user-friendly package.
