Creative Professionals 0404|USB Interface Cards

Description

Premium 24-bit/192kHz A/D and D/A converters (A/D: 113dB SNR, D/A: 117dB SNR) deliver unmatched USB audio fidelity

E-MU XTC Class-A ultra-low noise Mic/Line/Hi-Z preamplifiers (-127dB EIN) with 48V phantom power and ground lift switches enable you to plug microphones, keyboards and guitars straight into your computer with professional results, while the built-in analog soft limiting circuit lets you record a hotter signal without fear of clipping

Comprehensive digital I/O with optical and coaxial S/PDIF (switchable to AES/EBU) and MIDI In/Out to easily connect all of your digital studio gear and instruments

Ultra-low latency USB 2.0 drivers offer accurate timing and playback of your recorded audio and software instruments

Hardware zero-latency direct monitoring (mono/stereo) allows you to record and overdub with no annoying delay

Plug-and-play operation with hands-on control of all major functions like master level, direct monitoring, preamplifier controls and more

Cross-platform support (Windows XP/x64 and Mac OS X) and compatibility with most popular audio/sequencer applications (Windows: ASIO2, WDM, MME, AC-3 and DTS Passthru; Macintosh: Apple CoreAudio, CoreMIDI, AC-3 and DTS Passthru)
