INTRODUCTION: The DR-17 is the consumer version of a CD recorder, this means that the SCMS (Serial Copy Management Syste

17、m) is included. The DR-17 can only record on the Audio CDRs (Consumer Use). The DR-17 is suitable for recording and playback of CD-RW discs (CD-Re Writable disc). 2. OPENING THE PRODUCT: The product can be opened by removing the top cover (8 screws). Once the product is opened one can have access to

18、 the several PCBs and the main module. To have access to the Display PCB, the Headphone PCB and the lever PCB first the front cover has to be removed (See dismantling instructions on page1-7).

With HDCD, you get the body, depth and emotion of the original performance - not a flat, digital image. HDCD encoded CDs sound better because they are encoded with 20 bits of real musi

21、c information, compared to 16 bits for all other CDs. HDCD overcomes the limitations of the 16-bit CD format by using a sophisticated system to encode the additional the CD format. In addition, HDCD Precision Digital Filtering has the benefit of improving the sound of all digital recordings. This me
