U44

Introducing the U44: the ultimate software-controlled audio interface, designed for seamless live
performances, live streaming and recording. Packed with professional features, it offers simplicity
and flexibility, whether you’re on stage, streaming live, or in the studio.

The standout feature of the U44 is its intuitive, knob-free design. With no physical switches, faders,
or dials, everything is controlled through the powerful iCON iO Pro software and displayed on a
large, easy-to-read 7-inch TFT screen. This advanced virtual mixer and plugin host gives you
complete control to:
– Effortlessly route any audio input to any output,
– Apply plugins on individual channels or globally via two Aux channels to shape and enhance your
sound,
– Adjust key settings like sample rates and buffer sizes directly from the software, while monitoring
CPU usage.

Equipped with pristine preamps, the U44 delivers exceptional AD/DA conversion rates (122dB
analog-to-digital, 127dB digital-to-analog), two Neutrik® Combo XLR mic/line inputs, and two
1/4-inch line/instrument inputs. With iCON’s groundbreaking iO Pro software, you can easily save
and recall your settings using ‘snapshots,’ ensuring your perfect setup is just a click away—no more
fumbling with physical controls.

The U44 features the proprietary UNI OTG USB-C connector, allowing seamless direct connection to
internet streaming platforms. Designed with live streamers, podcasters, and engineers in mind, this
advanced technology ensures fast and reliable access for real-time broadcasting. Whether you’re
streaming a live performance or hosting a podcast, the UNI OTG system—developed by iCON for
optimized, hassle-free connectivity—keeps your workflow smooth and efficient (OTG cable and
Apple Camera Kit required).

Experience the freedom of full control, precision sound, and ultimate convenience, all without the
clutter of traditional interfaces.
