    2. Installation 2.1 System Recommendation U22 XT is not simply a standard digital audio interface, but a high-resolution device capable of advanced processing of audio content.

    Via Config > Latency in the Control Panel it is possible to change the latency setting (also called “buffer size”) for the driver of U22 XT. A smaller latency is the result of a smaller buffer size and value. Depending on the typical application (e.g. for playback of software synthesizers) a smaller latency is an advantage.
