Roland U.S.

Mobile Connectivity with Pro-Studio Extras

More Info

High-Resolution Performance
Don’t let its compact size (or body) fool you — the UA-25EX is a full-featured, professional audio interface with extras you wouldn’t expect in its size and price class. It’s capable of handling audio at 24bit/96kHz resolution, and boasts newly-developed high-end mic preamps, plus proquality balanced audio inputs and outputs, and an integrated low-noise, wide-range power supply.

Analog Compression & Limiting
The UA-25EX features a newly-developed analog compressor with variable attack times and threshold control for smooth capture of vocals or dynamic instruments. The accompanying limiter prevents input clipping from occurring so you’ll never lose those perfect takes.

Pro-Quality Shielding with Ground Lift
With its high-grade aluminum chassis, the UA-25EX can withstand hard impacts, and is shielded against high-frequency interference from other electrical components. Should a ground loop occur, the new ground-lift function eliminates the noise by disconnecting the sleeve pin of the master output from the earth ground.

Bundled Software
Included with the UA-25EX is the Production Plus Pack from Cakewalk by Roland, a feature-rich recording software bundle consisting of SONAR LE, Project 5 LE, and Dimension LE for PC-based recording. The CD-ROM also includes the latest ASIO, WDM, and MME drivers for Windows XP and Vista (32-bit versions), plus CoreAudio drivers for Mac OSX.
