• Internal directs Mobile I/O to use its internal clock. You must select this if you want to set the sample
rate from the Mobile I/O. If any other clock source has been selected, the console will not allow you to
change the sample rate since the sample rate is determined by the external clock source.
• WC (44/48) directs Mobile I/O to clock off of an external Word Clock Source at single rate (e.g. fs =
32k-50k)
• WC (88/96) directs Mobile I/O to clock off of an external Word Clock Source at double rate (e.g. fs
= 64k-100k)
