USB 2.0 Audio Interface
E-MU’s 0204 USB Audio Interface is the ultimate portable 2-in/4-out USB audio interface for PC and Mac, offering pristine 24-bit/192kHz recording and playback, direct monitoring and a host of professional features in a compact, USB bus-powered package. The 0204 USB provides users with two Class-A preamps that can be run independently or in stereo to amplify guitars, keyboards or microphones, with individual ground lift switches for optimal audio performance.
The E-MU 0204 USB 2.0 features:
- Premium 24-bit/192kHz A/D and D/A converters * (A/D: 113dB SNR, D/A: 113dB SNR) delivering you a pristine recording/capture and playback experience
- Ultra-low noise Mic/Hi-Z/Line preamplifiers with ground lift switches enable you to record microphones, keyboards or guitars directly into your computer delivering professional results (XLR, 1/4” TRS, and 1/8” 5V condenser mic input)
- Ultra-low latency USB drivers offer accurate timing and playback of your recorded audio and expressive control of your software instruments
- Independent headphone DAC path to enable separate playback and cueing for DJ applications
- Hardware zero-latency direct monitoring (mono/stereo) allows you to record and overdub with no timing delays
- Plug-and-play operation with hands-on control of all major functions like direct monitoring level, headphone level, and preamplifier gain to streamline your creative process
- Driver compatibility with most popular audio/sequencer applications letting you work with your choice of tools - (Windows XP (SP3 or greater), Vista/x64, Windows 7/x64:ASIO2 and WDM; Macintosh OS X (10.5 or greater): Apple CoreAudio)
