microphone is not recommended. Instead, pass the microphone signal through a microphone pre-amp (such as the M-Audio TAMPA™, DMP3™, or Audio Buddy™), and then connect the pre-amp output to the input of the Audiophile USB. Some additional cable and/or cable adaptors may also be needed to ensure proper connectivity.

The Audiophile USB also has digital inputs and outputs in S/PDIF format. These are available on RCA connectors, as stereo pairs.These jacks receive or transmit a digital audio stream that is independent of the analog audio streams. However, because of the bandwidth limits of USB there can be a tradeoff between the number of inputs and outputs that are active and the sampling rate and bit depth of the audio being processed. Also, you should ONLY activate the S/PDIF Input if you are connecting an active digital audio device to this input.This is detailed in the previous section,“The Audiophile USB Control Panel.”

Also detailed in the previous section is the use of the S/PDIF Output for sending encoded surround sound signals. Checking the “DD/DTS Pass-Thru” box in the Audiophile USB Control Panel will allow you send Dolby Digital, Dolby Surround, DTS, or any encoded surround sound signal to the S/PDIF Output of the Audiophile USB.You can connect this output to a home theater system, or any device that will decode this signal. Using most DVD players, select the “S/PDIF” option in the DVD players audio setup page, and your computer becomes a high-end home theater player in conjunction with the Audiophile USB.

Audiophile USB with Your Music Software

Once the Audiophile USB hardware and software drivers are properly installed, the Audiophile is ready for use with your music application software. Some software applications may require you to highlight or enable the Audiophile USB drivers within the program in order to use the Audiophile, while others may have a utility that analyzes or profiles the audio devices in your system and enables the drivers.Your software should have an audio device driver setup page. If you have problems locating it, consult your software’s documentation.

The Audiophile drivers include MME and WDM drivers for Windows, ASIO drivers for both Windows and Mac, and Sound Manager drivers for Mac. WDM drivers are a more modern driver architecture for Windows operating systems Me, 2000, and XP, but only certain programs like Cakewalk’s “Sonar” will take advantage of them. Other Windows programs will automatically access and use the MME drivers.WDM drivers, similar to ASIO, will give you
