Audio interface perfect for cleanly preserving your cassettes and vinyl

The UA-3FX provides a powerful set of tools in a compact, USB bus powered, audio interface. This 24-bit audio interface offers a variety of useful DSP grouped into three categories. In Mastering mode, the UA-3FX offers the following effects; Noise Suppressor, Enhancer, Low-boost, & a Limiter. In Listening Mode, it offers; Center cancel, Hi-boost, Low-boost, & Reverb. In Performance Mode it offers, Voice FX, Guitar FX, Chorus, & Delay. The UA-3FX also employs Adaptive Focus technology. Adaptive Focus Technology combines powerful DSP & 2 sets of 24-bit AD converters. The DSP acts as the brain for each AD converter offering more sensitive sound expression while maintaining a greater dynamic range. Ideal for laptop computers. Power supply from computer via USB cable. No need for AC Adaptor. Connect your audio equipment to your Mac or PC with the UA-3FX and just one USB cable!

High-quality recording/playback at 24 bits and AF Technology

24-bit I/O means the original quality is left as is. It
makes high-quality recording and playback possible. Using original AF (Adaptive Focus) Technology, the 32-bit DSP splits use of two high-sound-quality AD converters to make rich and powerful recording possible across the entire dynamic range of the source material.

Three variations with 11 digital effects built in

Including a noise suppressor and limiter, three
variations comprising 11 digital effects can be put to powerful use during recording or playback. Adjustment of sound quality is handled in real time by a single knob. Also, the loop back function makes it possible to adjust the sound quality of existing sound files and then re-save them.

A full range of I/O jacks starting with optical digital

In addition to an input jack for both guitar and mic, a dedicated mic jack with plug-in power (1/8” phone plug) and a convenient I/O line jack, for connecting audio devices are provided. A S/P DIF digital I/O port (optical) is also provided, which makes it easy to connect digital devices.

AF (Adaptive Focus) Technology

Edirol’s advanced AF (Adaptive Focus) Technology is the engine that gives the UA-3FX its expressiveness. The 32 bit DSP unit organically manages the two 24 bit AD converters, based on the demands of the source material. As a result, you get delicate expressiveness across the entire dynamic range of the material.
