More Info

Solid Aluminum Chassis — Portable and Durable
All of Edirol’s latest audio interface technology is condensed into the compact UA-25, giving the user the highest-performance 24-bit/96kHz recording and playback via USB.

Premium Audio Quality
The UA-25 uses powerful analog electronics coupled with well-matched A/D & D/A converters for superior audio fidelity.

Wide Variety of I/O Ports
Wide range of input and output ports in a compact case. A pair of Neutrik XLR/TRS combo jacks with Phantom power, Hi-Z port for guitar direct connection, S/PDIF optical I/O ports and MIDI IN/OUT ports.

Balanced I/O Ports
The UA-25 generates low-noise and has a wide-range power supply all via USB. Thanks to this, the UA-25 gives +4 dBu balanced professional audio input and output connections.

Two High-Quality Mic Preamps
Includes a pair of high-quality microphone preamps using premium analog components. It provides a clean recording environment to give a perfect recording.

Built-in Analog Limiter
Reduce sudden overloaded sounds or popping noises in your recordings. You can often get overloaded levels while recording on the fly. With this switch set, you can still achieve a high-quality sound while retaining a wide dynamic range. The side diagram shows the Limiter characteristics.

Zero-Latency Direct Monitoring
The UA-25 provides ultra low latency with maximum performance from popular music software such as Sonar, Logic, and Cubase. You can control Direct Monitoring from the front panel, not only for ASIO 2.0-compatible applications but also for others. Ideal for soft synths controlled from MIDI devices.

Driver Compatibility (WDM, ASIO 2.0, and CoreAudio)
The bundled CD-ROM has drivers for WDM (Windows XP/2000)/ASIO 2.0 (Windows, Mac OS 9) and CoreAudio (Mac OS X). In addition, you can choose to use either the advanced or OS-standard driver, via the ADV switch. Sound Manager for audio and OMS/FreeMIDI compatible on Mac OS 9 and Windows98 and Me as well.

USB Bus Powered
Just connect one USB cable. No need for an AC adaptor. In combination with your laptop, you get a quality field recorder. The UA-25 is the audio interface for mobile users — ideal for the traveling musician.
