Overview

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.
