Can I use 4X CDR media in a 52X CD Duplicator
Generally speaking you do not have to use media that matches the top speed of your duplicator. High speed CD DVD writers and duplicators might be advertised or sold as writing at up to 52X, however; you can lower the burn speed to match the media you have purchased, or rely on the recorder/writer to detect and burn at the correct media speed.
Some writers may not be compatible with all media, and will require a firmware update via a PC connection. DVD writers, recorder and duplicators seem to offer slightly more issues for consideration when buying media. Please consult your manufacturer for advice.
