I have a Myryad T10 CD Player and have just brought a Marantz CDR615 Professional recorder. My problem is I have connected the 2 together with a Digital lead but when I try to record I get an error code 21 which the manual states is a General Internal Communication error, their action to take is A) Hardware / Communication overflow B) power off / on. Not sure what A) means but have tried turning power on and off. I can Monitor the input ok so the signal is getting through to the Marantz. Any ideas???
