An affordable USB interface for on-the-go recording.

E-MU's Tracker Pre USB 2.0 is a portable audio interface and mobile preamp that works well with both Mac and PC computers. The Tracker offers you 24-bit/192kHz recording and playback, direct monitoring, and a host of professional features in a compact, USB bus-powered package. The E-MU Tracker Pre USB gives you 2 Class-A ultra-low noise Mic/Line/Hi-Z preamplifiers that can be run independently or in stereo to record guitars, keyboards, or microphones with optimal audio performance. CurrentMorph, a patent-pending circuit design, allows the Tracker Pre to offer +48V phantom power and use premium high-power converters while using only USB bus power.

E-MU Tracker Pre USB 2.0 Features:

24-bit/192kHz A/D and D/A converters (A/D and D/A: 112dB measured SNR performance) deliver USB audio fidelity, gold-plated connectors for better audio quality
Preamplified analog signals are available before the A/D converters, allowing the Tracker Pre to be used as a standalone stereo microphone preamp (using optional power supply)
Hardware zero-latency direct monitoring (mono or stereo) with continuously variable level control
Plug-and-play operation with hands-on control of all major functions like direct monitoring level, headphone level, preamplifier gain, and more
Independent ground lift switches for optimal audio fidelity/flexibility
USB bus powered (can also be powered using optional 5V power supply)
Two Class-A ultra-low noise Mic/Line/Hi-Z preamplifiers
Cross-platform support (Mac OS X and Windows XP32/XP64/Vista32/Vista64) and compatibility with most popular audio/sequencer applications (ASIO2, WDM, MME, Apple Core Audio and Core MIDI supported)
