UA-1D: SCMS Info
SCMS stands for Serial Copy Management System, which is a form of copyright-protection for digital audio. SCMS technology permits only one generation of digital-to-digital copying. This means that you can make a digital copy of the original material, but after that you cannot make a copy of the copy itself. It does not matter if what you are trying to copy is your material, or if you have permission to make the recording, the UA-1D will acknowlege an SCMS bit if it has been enabled and will not allow recording in these cases.
