Embedded Audio
The UDC-161 supports all four groups (16 channels) of embedded audio at full 24 bit resolution in
both SD (with extended data packets) and HD.
Analog Audio
The UDC-161 supports 8 channels differential analog audio. The analog audio is encoded in such a
way as to make +24 dBu (analog) equivalent to 0 dBFS (digital). Analog audio conversion can be
disabled to reduce power consumption.
