Channel Word Length
When the incoming video is 3G or 1.5G HD-SDI (and you have the optional
license key for those video input and outputs), the default value for all Audio
Ch XX-XX Word Length parameters is 24 bits.
When the incoming video is SD-SDI, the default value is 20 bits. However, if at
least one channel is set to 24 bits, the corresponding embedder will enable 24
bits embedding.
The Audio Channel Word Length parameters are listed on page 56.
