Marantz CDR-510: Playback is good , recording is distorted

Could be dirt inside the machine causing the problem, or the wrong type of disc being used.

It is due to some mechanical failure to the disc loading unit. It can be repaired. A broken gear wheel or a broken rubber belt can cause this. Contact any service technician. There is no need to bu any substitution for this mechanism. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/

No! since the process has begun it most be finalized through the Marantz CDR 300.

I get the same problem, and I use Maxell Music CDs as the recorder won't take anything else. Sometimes a message comes up saying, bad CD

Hi,
It sounds like you haven't followed the last step to the burning procedure. All you need to do once you've completed burning your disc is to Finalize the disc. Read below why you need to finalize as well as the steps to follow in order to finalize the disc.
Hope this helps ;)
How to Finalize Finalizing is writing the TOC (table of contents) on a disc so a CD player can recognize the number of tracks, the total time for each track, and their location on the disc. A recorded disc must be finalized to playback on a standard CD player. Once finalized a CD-R disc can be played on CD players that support CD-R playback. CD-RW discs can only be played on CD players that support CD-RW playback. Consult your CD player owner's manual to confirm supported formats. Finalizing is necessary to: • be able to play a recorded CD-R or CD-RW disc on a CD player • prevent further recording on a disc • avoid erasing tracks on a CD-RW disc • record text information onto a disc you record Notes: • A finalized CD-R disc can never be recorded onto again. • A finalized CD-RW disc can be unfinalized for more recording. • The CDR300 can play back unfinalized CD-R or CD-RW discs. • SYNC REC+FINAL mode automatically finalizes.
Here are the steps in order to Finalize your disk
1 Push Stop. The display shows the number of tracks and their total playing time. 2 Push FINALIZE. FINALIZE is displayed for about 3 seconds.

If you're recording an analog source the recorder won't automatically start. You have to start it in sync with the playback.

If you're trying a synchronized digital recording...

Page 28 of the manual says

Start playback on the selected source.

The CD recorder starts to record simultaneously and recording in progress is shown. The remaining recording time left of the CDR(W) is displayed.

Note: If you start playback on the selected source within a track, recording starts at the beginning of the next track or after 2.7 seconds of silence in analogue recordings.

Hi, I am brand new to this site. So I may not be very good. However your prob sounds like one I had a few years back. I solved mine by using two pencils, one in each hub.
Then winding manually from one to the other. This is quite time consuming, but it worked for me. Hope this helps, if not, sorry for wasting your time.

I have the CDR-200 and did not have the manual either. However, I did discover the same problem and found the solution. There is a "confirm" button on the front of the unit under the display area. After you press the record button "Record" will begin to flash in the display area and then you press "Confirm". It should start recording. Note however the following:

BURNING FROM EXTERNAL CASSETTE OR PHONO
Before starting this procedure make sure you have an AUDIO recording CD in the RECORDER tray of the CDR-200. A regular CD-R type of disc for computers is not going to work and may cause an annoying message on the display which does not go away until you put the right type of recording CD in the unit. It must be either an AUDIO CD-R or an AUDIO CD/RW.

1. When copying from an external cassette deck, you should set the source (press source button) until the setting is "Analog".

2. The "Dual" button should not be in effect. In the lower right portion of the screen you should only see a small number "1" with a circle around it. This indicates the CDs currently being used by the burner. In "dual" mode you can copy from the Playback CD of the CDR-200 to the Recorder CD. In dual mode you see "1" and "2" with circles around them. The active CD tray will flash on the display.

3. When copying from an external cassette unit, you use the "Record" button to start the recording. At the end of the cassette track you MUST press the STOP button by the CD Recorder tray. After you press STOP the unit will say "Update" which indicates it is closing out the track on the CD-R. You can continue to write tracks by pressing RECORD again, then CONFIRM when the tape is positioned at the right PLAYBACK track. It is usually helpful to have a few seconds of blank tape at the start of the PLAYBACK track before pressing RECORD. Press play on the cassette deck, then RECORD followed by CONFIRM on the CD burner.

4. When the track has finished burning you must press STOP to close the track on the CD-R. After you press STOP, the unit will display "Update" to indicate it is updating or closing the track. When the process completes, the unit will display the tracks it has written to the CD-R and will be ready for you to copy another track or FINALIZE the CD-R. When the unit is waiting after the STOP, you can change the cassette tape, reposition to a playback track and ready the playback tape for more recording. When the PLAYBACK tape is ready repeat STEP 3. Repeat steps 3 and 4 until you have about 14 or 15 tracks on the CD-R.

5. When you have finished recording about 14 or 15 tracks onto the CD-R, you will want to finalize the CD-R. Press the FINALIZE button, and then press the CONFIRM button. You will see the the unit start to display the progress of the finalize by advancing the level meters of the left and right channels in the display. When the unit is finished finalizing it will return to the number of tracks display for the CD-R. After finalizing the CD-R you can play it back to make sure the burn was successful. Be sure to wait for the tracks display before removing or playing the CD-R after the finalize is done. Removing before the finalize is done may damage the unit and may render the CD-R bad.

BURNING FROM THE PLAYBACK CD
Before starting this procedure make sure you have an AUDIO recording CD in the RECORDER tray of the CDR-200. A regular CD-R type of disc for computers is not going to work and may cause an annoying message on the display which does not go away until you put the right type of recording CD in the unit. It must be either an AUDIO CD-R or an AUDIO CD/RW.

1. Set the unit to "Dual" mode. As described above, you will see "1" and "2" with small circles in the lower right portion of the display.

2. Make sure the "Source" mode is set to "Analog" by repeatedly pressing the SOURCE button until it shows "Analog".
3. When copying from the PLAYBACK CD tray you will not use the RECORD button by the CD Burner tray. You will use the 'DUB" button just to the right of the display.

4. Put an audio CD in the PLAYBACK CD tray and press the skip track button ">>" until you arrive at the track you wish to record from. If the track you want to start at is track 1, then you don't need to skip tracks.

5. When positioned at the correct playback track, press the DUB button. The unit will show "CDR" and then "DUB" on the display. When it says "DUB" press the CONFIRM button. The unit will start recording. You can adjust the record level during the first few seconds to make sure you don't have the recording volume level set too high.

6. When the track is finished, you should see the unit indicate on the display "Update". This indicates it is closing the track and it should do this automatically. If it does not do this you may have to press STOP near the RECORDER Tray to force closing of the track. Usually the unit indicates "AUTO" in the display area and I believe that is what controls the automatic track numbering feature. I am not sure how the AUTO feature is turned on. I noticed on the CDR-200 it is on by default.

7. After the UPDATE is complete, the unit will display the number of tracks it has written to the CD-R. You can at this point change the PLAYBACK CD to another one or advance to another track for continued recording. When at the correct track simply go back to step 5 and continue.

8. When you are all done copying tracks from one or more CDs, and you wish to finalize the CD press FINALIZE and then press CONFIRM to start the finalize process. I noticed on the CDR-200 if you wait too long after recording a track the unit may start the finalize process automatically. This happened after at least 5 minutes. It is best to try and stay with the copy process to monitor what is happening. The finalize can also start if you have written to many tracks to the CD-R and it runs out of space. Typically, your safe if you burn about 14 to 15 tracks to a CD-R at a time. You might be able to fit more if the tracks are very short (2-3 minutes each).

One last note about the connections on the back of the unit. Read the labels of the connections on the back very carefully. The CDR-200 and probably the 201 have separate outputs for the PLAYBACK CD (CD) and BURNER CD (CDR). You will want to connect these to seperate inputs on your audio amplifier. Or you might also wish to merge them using adapters into one input on your audio amplifier. If you keep them separate you will need to change sources on the audio amplifier to hear each tray. For example, you might need to switch to "CD/TAPE" for the CD, and "AUX" for the CDR. It is probably easier to merge the two using audio adapters which can be readily obtained from RadioShack.

I hope this helps!

Sony say in the manual that if you record high bit-rate mp3's the sound may be intermittent. I feel this is due to the decoder having to move ALOT of bits around to play, try some makeing a disk with mixed rate mp3's on. e.g.) some 64Kbps, some 128, some 192, and some as high as you can get and see if there is any differ Luck

Is it just the analogue inputsthat do this? Soulnds like a faulty input board.
