U-Mix Control Pro - Standalone Mixer?

Hi all,
Quick question regarding the U-Mix Control Pro, which i'm looking into buying...
It says in the specs: "Regular vinyl/CD: plug in your vinyl or CD players to the controller’s built-in soundcard and play your traditional vinyl and CD records using the Bypass/through mode (line-input)."
Does this mean that the controller can be used like a standalone analogue mixer, without any computer connected? Is this where you would use a PSU to power it?
Thx for clarifying!
Rgrds,
