Questions

Q1 / Why will the unit intermittently update when the customer is using the correct procedure and compact disc? When this happens, the display will not change.
Q2 / Why does it flash “dig” even though it hooked up correctly?
Q3 / Can you make a copy of a copy when using an analog source?
Q4 / Why will the unit stop after recording for a while and display “full”? There is plenty of recording time left on the disc.
Q5 / Can you record without any pauses or track increments?
Q6 / How much time does the fast dub mode save on a 74-minute disc?
Q7 / In the manuals for CDR it states CD-R disc will play on all CD players. After finalizing some disc will not play in other units. How can we tell which units will be compatible?
Q8 / When using a mixer that has a receiver, how should it be connected?
Q9 / How can you insert a 5-10 second delay or remove delays between tracks?
Q10 / When using the correct disc, what would cause the unit not to finalize?
Q11 / What is the optical cable for; is it necessary for all recordings?
Q12 / Why can’t you record from a copy that was created on the CDR765?
Q13 / Explain analog and digital signals.
Q14 / What are the differences between the 560 and the other models other than the size of the unit?
Q15 / Why does the CDR only accept Philips Magnavox and TDK blank digital disc?
Q16 / Why does the unit shut off if there is a pause in a song?
Q17 / Why do the new units read “No Disc” or “No Audio”?
Q18 / Why won’t the record level in digital recording adjust automatically?
Q19 / Why can’t the CDR record old LPs from turntables?
Q20 / Why won’t the CDR connect into an FW unit?
Q21 / Why isn’t the Philips Magnavox blank disc that comes with the unit working properly?

Answers

A1 / Updating is writing to the PMA (Program Memory Area) on the disc. Updating is necessary to have all TOC information stored on the used disc. Writing should not be interrupted, for that nothing changes on display!! (back to Q1)
A2 / Choose the correct digital input. Via the INPUT or SOURCE key depends on model, the selection can be whether Optical or Coaxial, at the moment the correct connection is chosen flash will stop and dig is displayed. If the problem persist even though all the connection is correct then the signal may not be a consumer source conform to IEC 958 but probably a professional source (back to Q2)
A3 / Yes (SCMS is only valid for digital copies)(back to Q3)
A4 / In case Offtrack/Misrecording occurred.
¨  Misrecording may occur through:
·  switching off the set during recording,
·  scratches on the to be recorded disc
·  dust on the to be recorded disc
·  shocks or bumps against recorder.
¨  Offtrack may occur through
·  Misfunctioning of the recorder (back to Q4)
A5 / Pauses depend on source. Track increments kept out by switching auto track/manual key to manual track increment and not activating the next key. (back to Q5)
A6 / Approx. 37 minutes (back to Q6)
A7 / Then the CD player is out of CD-system specification. (back to Q7)
A8 / The output of the mixer is the input of the CD-recorder. Mixer inputs depends on sources and mixer functions. (back to Q8)
A9 / Which function is active than, analog or digital? Inserting delay only possible in analog function by pushing pause button on external CD player. Only 3 sec delay is possible.
Removing is not possible. Only by beginning or ending of the track via start and stop manually. (back to Q9)
A10 / See also 4. Offtrack or when the set was switched off (or power drop) during recording. Display shows “disc recover”. (back to Q10)
A11 / Via optical cable external distortions are prevented. Radio Magnetic distorting signals like hum can be prevented via optical cable but those can influent the coaxial connection slightly. (back to Q11)
A12 / Because the SCMS does not allow a second digital copy of a copy. If you are using dubbing, the CDR765 will record the disc in analog mode automatically. (back to Q12)
A13 / Before CD player was invented all Audio sources were generating analog output signals. These signals between 50 Hz and 20kHz were loosing a little bit or very much of the original quality after each operation and or storing. After the invention of the digital conversion the quality of the once defined information is kept and safeguarded by a correction system that secures the original quality.

See also terms:

Analog signal = Continuously varying electrical signal in which the variants directly represent changes in a physical quantity, such as light intensity (brightness), light frequency (color) or air pressure (sound).

Digital signal = A signal containing information in numerical form usually consisting of binary digits. Analog signals are often converted to digital form before being processed, stored or transferred, because a digital signal consists of a stream of simple pulses which are largely immune to the effects of interference or distortion. (back to Q13)
A14 / CDR560 compared with CDR760 is only dimension differences of the unit and the absent of a headphone socket. CDR765 = CDR760 which includes an internal CD player that optimizes the recordings from prerecorded CD-disc to CD-recording disc with double speed recording facility.
CDR880 is top of the bill with conversion facilities to apply digital DAB sources (32 kHz) and digital DAT sources (48 kHz) CD-players functioning with digital 44.1 kHz source do not have to be converted. (back to Q14)
A15 / Besides Philips Magnavox and TDK, other brand of Digital Audio CDR disc is also acceptable. Digital Audio disc for Customer is needed for copy protection regulations. The consumer has to pay rights for the artists. These discs have a ‘flag’ on it that the recorder will recognize. The Audio recorder will only recognize discs with a flag on it. (back to Q15)
A16 / In case the input signal is interrupted the set will automatically switch off after 20 seconds. (Can be overruled by switching off the auto track feature) (back to Q16)
A17 / On display No disc is indicated in case the disc is not recognized. The indication No Audio on display means that the loaded disc is not a Digital Audio CD-recording disc. (e.g. a CD-ROM disc) (back to Q17)
A18 / Because this requires complex digital signal processing and it will affect the digital signal (Meaning no bit for bit recording)(back to Q18)
A19 / Recording can be done via an external amplifier, just connect the turntable input to the amplifier and the amplifier output to the CD-Recorder. (back to Q19)
A20 / Not all FW units are yet fit for CDR. CDR is quite new in the market. The current MINI designs are not (yet) having digital outputs. In 1999 the majority of mini sets will have a digital output (back to Q20)
A21 / See also answer 4. Offtrack/misrecording might have occurred. (back to Q21)
