Computer Requirements COMPUTER REQUIREMENTS The recommended computer system requirements for the E-MU 0204 USB are listed below. Windows • Intel® Pentium® or AMD® processor — 1.2 GHz or faster • Intel, AMD, or 100% compatible motherboard & chipset • Microsoft® Windows® XP (SP3 or greater), Vista/x64, Windows 7/x64 Drivers • 1 available (Hi-Speed) USB 2.
Software Installation SOFTWARE INSTALLATION Windows XP, Windows Vista or Windows 7 Follow these instructions to install the 0204 USB software on a Windows computer. 1. First connect the 0204 USB to your computer using the supplied USB cable, and turn it on. 2. If Windows prompts you with an Add New Hardware Wizard, click Cancel. 3. Insert the E-MU software Installation CD into your CD-ROM drive. If Windows AutoPlay mode is enabled for your CD-ROM drive, the CD starts running automatically.
Software Installation 6. Click the Yes button. 7. Restart your computer when prompted. You may now re-install existing or updated E-MU device drivers or applications. Macintosh OS X Follow these instructions to install the 0204 USB drivers and software on a Macintosh OS X computer. First, connect the 0204 USB to your computer as shown on page 12. Install the 0204 USB Software 1. Insert the E-MU Software/Manual CD-ROM into your CD-ROM drive. 2. Double-click on the E-MU icon on the desktop. 3.
Software Installation Setup the MIDI Devices NOTE: If you already have a MIDI Interface connected, you can skip steps 14-19. If you plan to use a MIDI keyboard, now would be a good time to set up your MIDI devices. Connecting a MIDI keyboard will allow you to use the virtual instruments provided in the software bundle and get the most out of your purchase. You’ll also need a MIDI interface such as the E-MU Xmidi 2x2 or Xmidi 1x1. 14. Click the MIDI Devices button. The window shown below appears. 15.
Software Installation 17. Connect the new external device to the E-MU 0204|USB by dragging between the input and output connectors. 18. The window below shows a properly connected MIDI device. 19. Press the close button to close the Audio MIDI Setup window. Uninstalling the Audio Drivers and Applications At times you may need to uninstall or reinstall the 0204 USB application and device drivers to correct problems, change configurations, or upgrade outdated drivers or applications.
Connection Diagram CONNECTION DIAGRAM Microphone or Line WARNING! Use only a USB 2.0 certified Hi-Speed cable (like the one supplied) for the USB connection. Using a USB 1.1 cable may cause erratic behavior and degraded performance.
Controls & Headphone Output CONTROLS & HEADPHONE OUTPUT 7 1 2 3 4 5 6 1. Signal Level & Clip Indicators The LED signal level indicators make it easy for you to set a proper signal level. When the input level is too low, the green and red LEDs will both be off. When the input level is correctly set, the green signal LED should be flickering. If the signal level is too high, the green and red LEDs will both be on. The red clip indicators show that the input level has exceeded 0dBFS. 2.
Input/Output INPUT/OUTPUT 8 9 10 11 12 13 8. USB Connects the 0204 USB to your computer via the supplied USB cable. The USB connection provides two-way communication when connected to the computer. The 0204 USB receives its power from the USB. Always connect to the USB jack on the computer itself and NOT to a low-power USB connection that may be present on your computer keyboard or other USB peripheral. 9. Main Outputs The unbalanced outputs are normally connected to your monitoring system.
E-MU USB Audio Control Panel E-MU USB AUDIO CONTROL PANEL After you have successfully installed the audio drivers, launch the E-MU USB Audio control panel. The E-MU USB Audio Control Panel is shown below. • Windows: The E-MU USB Audio control icon will be visible in the Taskbar, which is normally located in the bottom right of the screen. It can also be launched from the Start Menu (All Programs, Creative Professional, E-MU USB Audio Application).
Headphone Source HEADPHONE SOURCE The stereo headphone output can either duplicate the main outputs, or it can be used as another completely independent pair of outputs when using ASIO. This setting is controlled from the 0204 Control Panel. The headphone output is a highquality signal, with increased power for driving headphones. With the Headphone Source set to Main Out 1/2, the headphone output duplicates the signal on the main outputs.
Direct Monitoring DIRECT MONITORING Direct monitoring allows you to monitor inputs without having any software open. It can also be used as an alternative to software monitoring if you desire the lowest latency monitoring possible. When using a computer for digital recording, an audible time delay occurs while the audio signal is being input to the computer, processed by the software and then returned to the output for monitoring. This time delay is called Latency.
Audio Recording Software AUDIO RECORDING SOFTWARE Now that you’ve installed the 0204 USB, you probably want to start using it! The 0204 USB is only one half of the equation—the hardware interface that translates audio signals into the digital language of your computer. The second half of the equation is the software recording application, which records and allows you to edit the audio on your computer. Acoustica Mixcraft LE 4™ We have included Acoustica Mixcraft LE 4 for PC users.
Troubleshooting TROUBLESHOOTING Can’t hear Windows Media Player in Windows If you have, or ever have had, another audio device installed in your PC, you may have to set the E-MU 0204 USB as the “Default Audio Device”. 1. Open the Control Panel, then select Sounds and Audio Devices. 2. Click the Audio tab and select the E-MU 0204 USB as the Default device under Sound Playback. 3. Click the Volume button under Sound Playback and turn up Wave volume.
Internet References Simultaneous WDM/ASIO Playback (PC only) The 0204 USB only supports playing back one stream format at a time on the PC. Each of the two mentioned stream types has an associated priority. If a higher priority stream type is opened while a lower priority stream is already playing, the lower priority stream will stop playing. The stream priorities, from highest to lowest, are ASIO, WDM. Headphone Source using WDM (PC only) The Headphone Source feature only functions using ASIO at this time.
