The M-32 DA Pro supports the following sample rates:
Supported sample rates
Single speed
Double speed
Quad speed
If the device is clock master, these rates always correspond to the actual sample rate used.

11.3.1. Slave Mode

When the device is slave, certain deviations are automatically accepted to avoid interruption of the
outgoing audio signal when the sample rate changes. This is called Intelligent Clock Control (ICC). It also
handles deriving a sample rate of double or quad speed based on an incoming rate.
