The USB 2.0 port serves as a digital audio interface between the PowerMate and a PC or Mac.įour channels can be transmitted in either direction simultaneously. Below I have added a section (in italic) from Dynacords webpage regarding the USB audio interface: My interface is a Dynacord PowermWatt amplifier which according to my knowledge should provide 2 stereo tracks or 4 mono tracks though the USB cable. I have had mayor issue about finding out how to record in tracks through Logic Pro as well as Garage Band.
