RME Fireface UCX: Highest Rated USB Audio Interface With 8 Analog Inputs - 2019.12

Gearank Recommended

The Fireface UCX first appeared on our recommended list in December 2017 when it took the top rated spot in the 8 Analog Input category.

It held that position until October 2020 when it became the equal top with the Focusrite Scarlett 18i20 3rd Gen.

It dropped down to second place behind the Focusrite Scarlett 18i20 3rd Gen in October 2021 where it remains today.

It also appeared on our list for iPad Compatible USB Audio Interfaces from September 2021 until August 2022 when we reduced the maximum price for that guide which in turn excluded it.

The RME Fireface UCX carries over tech from their UFX line like RME Micstasy preamps and Hammerfall converters.

The preamps feature low distortion, excellent signal to noise ratio and a flat response and the converters offer excellent analog to digital conversion.

With 8 analog inputs, including two combo XLR inputs with the aforementioned preamps, the UCX has all your mic and instrument needs covered.

Connectivity is also flexible with USB 2, USB 3 and Firewire 400 compatibility.
