1.Servicing the DR6000 1.1 INTRODUCTION: The DR6000 is the consumer version of a CD recorder, this means that the SCMS (Serial Copy Management System) is included. The DR6000 can only record on the Audio CDRs (Consumer Use). The DR6000 is suitable for recording and playback of CD-R W discs (CD-Re Writable disc).
Page 4 This PCB consists of power supply part and audio part. The power suppluy part delivers the several voltages for the diffrent PCB in the DR6000. On this power supply sevel fuses (secondary side) are mounted on this PCB. The audio part takes care that the signal from CDR main module is converted into an analog signal via DA converter and outputs the analog signal.
