Latency with Roland duo-capture mk2

A friend gave me a roland duo-capture mk2 that he hadn’t used. I eventually installed it (windows8.1)
It is supposed to eliminate latency (why not just say delay?).
I had a quick try with audacity, but second track was still not in sync.
Anyone used this box?
Also Cakewalk sonar le came with it. Opinions?

If you hide your questions at the end of old and unrelated topics, you are less likely to get relevant replies than if you start a new topic on the forum board appropriate for your operating system, with a relevant topic title.

because that would be even more vague than saying “latency”.

Have you set up latency compensation?
