EDIROL Announces UA-25EX USB Audio Interface

EDIROL announced a new version of its UA-25 24bit/96kHz USB Audio Interface. The UA-25EX succeeds the EDIROL UA-25, and adds pro-grade microphone preamps, a newly developed analog compressor/limiter, and ground-lift functionality for studio and stage.

For the first time in an audio-interface product, the UA-25EX has ground-lift functionality - very useful for live and home recording. The UA-25EX is Mac/PC cross-platform compatible. It supports WDM, ASIO 2.0, and Mac OS X Core formats. Enjoy low-latency audio performance on both platforms.

The device is bundled with Cakewalk Production Plus Pack CD-ROM, including the popular SONAR LE recording/composing application.
