The audio interface on the VL-EPICs-36 is implemented using the IDT 92HD75B Audio Codec.
This interface is compatible with Intel's High Definition (HD) Audio Interface and is Microsoft
WLP 3/4 premium logo compliant, as defined in WLP 3.09. Drivers are available for most
Windows-based operating systems. To obtain the most current versions, consult the

J6 provides the line-level stereo input and line-level stereo output connection points. The outputs
will drive any standard-powered PC speaker set.
These connectors use IEC 61000-4-2-rated TVS components to help protect against ESD
