UA-101: USB Audio Interface

Features

The UA-101 is a half-rack, high-speed USB audio interface designed to turn your USB 2.0-ready computer into a powerful digital audio workstation. No other computer connection is required to get a full 10 inputs and 10 outputs at 24-bit/96kHz to the computer. The UA-101 is built to offer low latency and extraordinary stability. It’s the easiest-to-use yet most-powerful compact audio interface available.

Dedicated Monitor Output
The UA-101 offers dedicated monitor outputs, kept separate from its channel outputs 1-8.

All Balanced I/O
The UA-101 features all-balanced inputs and outputs with input level selection switches on inputs 3-8, offering either +4dBu or -10dBu levels.

Included Signal Router/Mixer Application
The UA-101 comes with a powerful software application that allows you to route your inputs to various outputs and adjust your input monitor mix. This application allows the UA-101 to be reconfigured in a variety of ways without requiring any cable swapping or changes in your DAW application.

Built-In Limiter
The UA-101 allows you more freedom in setting your recording levels with the built-in limiter. Prevent clipping in your recordings. Get high-quality studio recordings with a wide dynamic range. No more worry about clipping a live recording or losing valuable signal because of brief loud transients.

The UA-101 uses premium analog components perfectly matched to its A/D converters for incredible fidelity. All audio is processed internally at 40-bit resolution to ensure accurate recording.

MIDI I/O
The UA-101 offers both MIDI input and output to connect external MIDI devices to your DAW.

Optical S/PDIF Input and Output
Channels 9 and 10 are dedicated S/PDIF digital channels, offering convenient connection to DAT, Minidisc, or other digital sources and destinations at up to 96kHz.

Low-Latency Driver Support
The UA-101 offers incredibly low latency through both WDM and ASIO 2.0 support for superior performance in your home studio.

High-Speed USB (USB 2.0) and Full-Speed (USB 1.1) compatible
The UA-101 is the first multi-channel high-speed USB audio interface to offer basic compatibility with USB 1.1. When connected through USB 1.1, the UA-101 will function as a stereo audio interface at 44.1 or 48kHz with any Win98 or later PC or Mac OS 9 or Mac OS X computer. When connected to Windows XP computer running USB 2.0, the UA-101 offers the full set of I/O options to your computer.
