The 0204 USB 2.0 from E-MU is a compact and portable 2-in/4-out USB audio interface, especially attractive to the laptop computer user. It offers 24-bit/192 kHz recording and playback (limited to 96 kHz on a Mac), direct monitoring, and a host of professional features.

The unit features a microphone preamp that doubles as a balanced line input, and a Hi-Z/line input. A 1/8" mini jack is provided for use with microphones that feature this size connector. This input can power 5V condenser microphones.

The two Class-A preamps can be run independently or in stereo to amplify guitars, keyboards or microphones, with individual ground lift switches. The package includes Acoustica Mixcraft LE 4 software for Windows that provides everything needed to create, record, edit and mix.


  • Premium 24-bit/192 kHz analog-to-digital and digital-to-analog converters delivering a pristine recording/capture and playback experience (Mac analog operation up to 96 kHz only)
  • Ultra-low noise microphone/Hi-Z/line preamplifiers with ground lift switches enable you to record microphones, keyboards or guitars directly into your computer delivering professional results
  • USB Hi-Speed with full 24-bit resolution at all sample rates and stereo in, stereo out at all sample rates
  • Ultra-low latency USB drivers offer accurate timing and playback of recorded audio and expressive control of 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 (disabled at 176.4/192 kHz)
  • Plug-and-play operation with hands-on control of all major functions like direct monitoring level, headphone level, and preamplifier gain
