The audio interface on the Iguana is implemented using an Integrated Device Technology, Inc.
92HD87B1X5 Audio Codec. This interface is Intel High Definition Audio compatible. Drivers
are available for most Windows-based and Linux operating systems. To obtain the most current
versions, consult the Iguana product support page.
The J19 main I/O connector provides the line-level stereo input and line-level stereo output
connection points. The outputs will drive most amplified PC speaker sets.
The following table shows the pinout of the audio connector J3 on the VL-CBR-5013 breakout
board.
Note:
In Windows, the rear line-in audio input is configured by default as a microphone
input. To configure it for audio input, disable the microphone boost to eliminate
audio distortion.
