2.1 CDR loader (CDR main module CDL3610/01):

This complete CDR loader is considered as not repairable in the field. therefore this module will be repaired centrally. A

module exchange procedure will be set up for this purpose. The module can be removed from the product by removing 10
screws 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 following parts:
`` CD Mechanism (CDM3610’). Underneath this mechanism a PCB is mounted which is adjusted to the mechanism (laser

current 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 recorded is converted into a suitable signal which

can be recorded on the disc.

Digital signals with an other sampling frequency then 44.1kHz will be converted in the sample rate converter (GDIN) to

44.1kHz.

Analog signals will be first converted into a digital converter by the AD converter.

This PCB also takes care that the signal from the CD (playback) is converted into a suitable digital signal (or analog via

the DA converter).

The main microprocessor controls the several functions of this PCB. The system software stored in a normal DIL

EPROM(7322). This EPROM(7322) is mounted on a socket, so software updates can be easily done at the dealer or

service agent.

2.2 Power SW Board.

This PCB contains the Power SW, which is jointed the Power bottom on the front panel. All parts are available as spare
parts.

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 diffrent
PCB in the DR-17. 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.
This PCB contains the output and input connectors also. All parts are available as spare parts.

2.4 Display Board.

This PCB contains the Display, which informs the user about the status of the recording/playback process and it also takes
care for scanning the keys on the front panel. The information from the keys is fed via a I C connection to the main
microprocessor on the CDR loader module. Information which needs to be displayed is also fed via this I C line from the
main 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.

as spare parts.

2.6 Analog Input Board

This PCB contains the analog input (RCA) connector. All parts are available as spare parts.

2.7 Level Board.

This PCB contains the potentiometer to adjust the level of the analogue input signal. All parts are available as spare parts.

2.8 Moter Board.

This PCB takes care for the tray speed control. All parts are available as spare parts.

3. TEST PROGRAMS.

The DR-17 has two built in test programs. These are the “Dealer Diagnostics” and the “Service Diagnostics”. Both
diagnostics can be used to determine which board or module is defect.

3.1 Dealer Diagnostics.

This test diagnostics the communication between the several ICs in the CDR module. To start the test press the buttons
<PLAY>+<STOP> simultaneously and switch on the power.
During this diagnostics the message “BUSY” is blinking on the display (this can last for a couple of minutes). When an error
is detected the message “ERROR” is displayed. For the meaning of this error the service diagnostics has to be ran.
Since no CD is used for this test, the playback and record parts of the module are not tested thoroughly.

3.2 Service Diagnostics.

This Diagnostics tests the main board and CDM assembly (also known as Basic Engine) of the CDR module and the
keyboard and display board.
If an error is detected, an error number is displayed which refers to the error.
The test is executed with a normal CD loaded, so the recording part of the CDM is not tested thoroughly.
To start the test press the keys <PLAY>+<NEXT> simultaneously and switch the power on.

See the attached sheet for a flowchart of the “SERVICE TEST PROGRAM”.

WARNING

All ICs and many other semiconductors are susceptible to
electrostatic discharges (ESD). Careless handling during
repair can reduce life drastically.
When repairing, make sure that you are connected with the
same potential as the mass of the set via a wristband with
resistance. Keep components and tools at this potential.

ATTENTION

Tous les IC et beaucoup d´autres semi-conducteurs sont
sensibles aux décharges statiques (ESD). Leur longévite
pourrait être considérablement écourtée par le fait qu´aucune
précaution nést prise à leur manipulation.
Lors de réparations, s´assurer de bien être relié au même
potentiel que la masse de l´appareil et enfileer le bracelet
serti d´une résistance de sécurité.
Veiller à ce que les composants ainsi que les outils que l´on
utilise soient également à ce potentiel.

WARNUNG

Alle ICs und viele andere Halbleiter sind empfindlich
gegenüber elektrostatischen Entladungen (ESD).
Unsorgfältige Behandlung im Reparaturfall kann die
Lebensdauer drastisch reduzieren.
Sorgen Sie dafür, daß sie im Reparaturfall über ein Puls­armband mit Widerstand mit dem Massepotential des
Gerätes verbunden sind.
Halten Sie Bauteile und Hilfsmittel ebenfalls auf diesem
Potential.

WAARSCHUWING

Alle IC´s en vele andere halfgeleiders zijn gevoelig voor
electrostatische ontladingen (ESD).
Onzorgvuldig behandelen tijdens reparatie kan de levensduur
drastisch doen vermindern. Zorg ervoor dat u tijdens reparatie
via een polsband met weerstand verbonden bent met hetzelfde
potentiaal als de massa van het apparaat.
Houd componenten en hulpmiddelen ook op ditzelfde potentiaal.

AVVERTIMENTO

Tutti IC e parecchi semi-conduttori sono sensibili alle scariche
statiche (ESD).
La loro longevità potrebbe essere fortemente ridatta in caso di
non osservazione della più grande cauzione alla loro
manipolazione. Durante le riparationi occorre quindi essere
collegato allo stesso potenziale che quello della massa
delápparecchio tramite un braccialetto a resistenza.
Assicurarsi che i componenti e anche gli utensili con quali si
lavora siano anche a questo potenziale.

Safety regulations require that the set be restored to its
original condition and that parts which are identical with
those specified be used.
Safety components are marked by the symbol

Le norme di sicurezza estigono che l´apparecchio venga
rimesso nelle condizioni originali e che siano utilizzati i

HDCD - High Definition Compatible Digital - is a patented process for delivering on digital media the full richness and detail of
the original microphone feed. When listening to HDCD recordings, you will hear more dynamic range and very natural vocal
and musical timbre. 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 music 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 means that the
Marantz DR-17, equipped with HDCD, will improve the sound of all digital recordings, whether mastered with HDCD or not.
