Main features
6 x 4 USB 3.0 Audio Interface with 4 x D-PRE and 32-bit/192 kHz support
The UR44C is a 6-in and 4-out USB 3.0 audio interface, featuring four world-renowned D-PRE microphone preamps and supporting 192 kHz and 32-bit audio quality to capture all the subtleties and expressiveness of any audio source.
True 32-bit resolution
The UR44C and the Yamaha Steinberg USB Driver support the 32-bit Integer format which can represent audio data in higher resolution compared to Float format. Together with a DAW (such as Cubase) which can fully utilize the 32-bit Integer data, they enable unprecedented audio resolution in your music production.
USB 3.0 & USB Type-C
The UR44C is equipped with a USB Type-C port and features USB 3.0 (USB 3.1 Gen 1) SuperSpeed mode while providing full compatibility with the USB 2.0 High-Speed mode. The USB Type-C connection provides enough bus power to operate the UR44C.
dspMixFx
The dspMixFx technology is powered by the latest SSP3 DSP chip and offers latency-free monitoring with highly acclaimed DSP effects, including REV-X reverb, for users of any DAW software.

dspMixFx UR-C
This software is for operating the convenient built-in DSP mixer and DSP effects. The DSP mixer allows you to mix up to six input channels down to one stereo output. A number of DSP effects for processing the input signals are also provided, and since the processing/mixing is hardware-based, there is no monitoring latency.

What is Loopback?
Loopback is a convenient function for broadcasting over the Internet. It mixes the input audio signals (such as microphone and guitar) with the audio signals playing back in the software in the computer into two channels in the UR44C, and sends them back to the computer. Refer to the section “Signal Flow” (page 34).
If the Loopback function is on while you are monitoring input signals from the UR44C via DAW software, it will cause loud noise. This is because an infinite loop of the audio signal is generated between the UR44C and the DAW software. When using the loopback function, turn off the monitor functions on your DAW software.
