office, where only a small amount of background noise is present.
EXPLANATORY NOTE
Although ADPRO FastTrace always passes audio at the maximum possible bandwidth,
the overall audio quality will ultimately depend on the quality of the microphones and
speakers connected to the ADPRO FastTrace and the level of background noise in the
environment. Tests should always be performed with the desired audio equipment to
obtain an understanding of the audio performance.
NOTE
Only selectable for Microphone Input.
