Features
Features Pristine 24-bit/192kHz A/D and D/A converters (A/D and D/A: 112dB measured SNR performance) deliver unmatched USB audio fidelity for pristine audio quality

Preamplified analog signals are available before the A/D converters, allowing the Tracker Pre to be used as a standalone high-quality 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)

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)
