Regardless of the type of sample rates, U2A automatically converts
the incoming digital audio signal to the sample rate of your choice in
real-time.

independent signal converter. In this mode, U2A is disconnected from the
computer, but it will send out any incoming signal to both analog and
digital output ports.
