The DR6000 can only record on the Audio CDRs (Consumer Use).The DR6000 is suitable for recording and playback of CD-RW discs (

19、CD-Re Writable disc).1.2 OPENING THE PRODUCT:The product can be opened by removing the top cover (6 screws). Once the product is opened one can have access to theseveral PCBs and the main module. To have access to the Display PCB, the Headphone PCB first the front cover has tobe removed (See dismant

The module can be removed from the product by removing 4screws and the transformer (see demounting the CDR module on page 1-7), and loosing the connectors.This module is the complete CD recorder, it contains the f

24、ollowing parts:CD Mechanism (CDM4009). Underneath this mechanism a PCB is mounted which is adjusted to the mechanism (lasercurrent settings are stored in EEPROM).Loader Assy. This mechanical assy takes care for the tray control.Main PCB. This PCB takes care that the (analog or digital) signal to be

25、recorded is converted into a suitable signal whichcan be recorded on the disc.Digital signals with an other sampling frequency then 44.1kHz will be converted in the sample rate converter (DASP) to44.1kHz.Analog signals will be first converted into a digital converter by the AD converter.This PCB als

26、o takes care that the signal from the CD (playback) is converted into a suitable digital signal (or analog viathe DA converter).The main microprocessor controls the several functions of this PCB. 1.2.2 Power SW Board.This PCB contains the Power SW, which is jointed the Power bottom on the front pane

27、l. All parts are available as spareparts.1.2.3 Power Supply and Audio Board.This PCB consists of power supply part and audio part. The power suppluy part delivers the several voltages for the diffrentPCB in the DR6000. On this power supply sevel fuses(secondary side) are mounted on this PCB. The aud

28、io part takes carethat the signal from CDR main module is converted into an analog signal via DA converter and outputs the analog signal.This PCB contains the output and input connectors also. All parts are available as spare parts.1.2.4 Display Board.This PCB contains the Display, which informs the

29、 user about the status of the recording/playback process and it also takescare for scanning the keys on the front panel. The information from the keys is fed via a I C connection to the mainmicroprocessor on the CDR loader module. Information which needs to be displayed is also fed via this I C line

30、 from themain microprocessor on the CDR loader module to the display controller.The parts for this PCB are available as service parts so this PCB can be repairable up to component level.1.2.5 Headphone Board.This PCB contains the headphone socket and potentiometer which controls the headphone volume
