Features
High-resolution 24-bit/96kHz performance with newly developed mic preamps and analog compressor/limiter

USB bus powered, low-noise, wide-range power supply

Two mic preamps and XLR/TRS combo jacks with 48V phantom power, Hi-Z port for guitar-direct connection, S/PDIF optical I/O, MIDI in/out

Ground lift for studio and live stage use

Bundled with Production Plus Pack from Cakewalk By Roland

High-Resolution Performance
Don't let its compact frame fool you - the UA25EX 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 24-bit/96kHz resolution, and boasts newly developed high-end mic preamps, plus pro-quality balanced audio inputs and outputs, and an integrated low-noise, wide-range power supply.

Analog Compression & Limiting
The UA25EX 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 UA25EX 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 UA25EX 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.
