Audio Sample Rate Conversion
Two check-boxes are provided to engage built-in sample rate converters for either (or both)
of audio channels 1 & 2, and 3 & 4. When checked, the incoming AES/EBU audio tracks are
converted to a 48K broadcast standard synchronized with video genlock.
Note: Audio sample rate conversion is not applicable for Embedded Audio and Audio Rate
Conversion boxes will be grayed-out if the SDI/ Embedded audio check-box is selected, or if the
XLR audio inputs are jumpered for analog audio.
