Possible cause of clicks/pops on aging Sony DAT?
I know all the cool kids have flash recorders now, but I've been more
than happy with my Sony DTC-2000ES DAT. Until this week, when a bunch of clicks/pops marred my recording. How can I best diagnose this? The details: Crown SASS-P with Crown phantom power supply, 1/4-inch to XLR converter cables, cheap 60m data grade tape as I can't find legit audio DATs any more. The recording was transferred to PC using the deck's digital out with an M-Audio Transit USB; the clicks also appear on the deck's analog outputs, in exactly the same patterns each time the tape is replayed. If any experienced DAT owners could take a listen to the noise (3.5 meg file) to see if it sounds familiar, I would sure appreciate it. http://www.mit.edu/~mike/2008-Sony2000ES-clicks.wav The clicks appear in the early part of the excerpt, but then disappear. Why did I get this noise? A bad tape? Do I need to use a cleaning tape? Is the deck (gulp?) on the fritz? I will try again with a different tape and having used a cleaning tape, but over 95% of the tape had no problem, so I wouldn't know how to be sure the problem was gone. Thanks very much for any insights. Mike -- Mike --- |

How can I best diagnose this? Hmmm .... The details: Crown SASS-P with Crown phantom power supply, 1/4-inch to XLR converter cables, cheap 60m data grade tape as I can't find legit audio DATs any more. Data grade tapes used to be certified, ie. physically verified while audio grade tapes were not. One of my reasons for getting a harddisk recorder was the increased occurence of loose debris from brand new tapes clogging a head on the dat. The recording was transferred to PC using the deck's digital out with an M-Audio Transit USB; the clicks also appear on the deck's analog outputs, in exactly the same patterns each time the tape is replayed. It may then be recorded on the tape or a tape error or something that happens in playback, but it should then not be exactly repeatable. If any experienced DAT owners could take a listen to the noise (3.5 meg file) to see if it sounds familiar, I would sure appreciate it. http://www.mit.edu/~mike/2008-Sony2000ES-clicks.wav The clicks appear in the early part of the excerpt, but then disappear. See http://www.muyiovatki.dk/click.png for an image of one. It looks very different from the oddities I have seen, those have been single samples totally out of line. Your first recourse is to try playing the tape on a different deck, if avaiable. Clickfixing with a quality declicker - I tried Audition, but there are others - can fix the clicks if unbearable. They are not really really bad, so if it is not for release or demo use my suggestion is to live with them. Why did I get this noise? A bad tape? Do I need to use a cleaning tape? Is the deck (gulp?) on the fritz? The two good Sony DAT's (77 and 2000) are amazing wonders of reliability and autocleaning. But that does not mean that getting the deck cleaned might not be a good idea. It is not all that difficult, but it is a skilled task. I will try again with a different tape and having used a cleaning tape, but over 95% of the tape had no problem, so I wouldn't know how to be sure the problem was gone. The 2000 has the property of always wanting to rewind a cleaning tape after discovering that there is no audio on it. That is very bad because the usual recipe for cleaning tape use is to NOT rewind. Otoh they don't seem to ever really _need_ cleaning. It is my asumption that the actual mechanism is the one also used in computer DAT drives. There are some oddities to be aware of with computer grade tapes: they are a bit smoother and come in thin and very thin and even thinner and then way to thin versions. You DAT expects a 2 hour tape at most, and the shortest computer tapes I could find ended up at 3 hours. Do not do a lot of shuttling, and preferable wind and rewind, oh ... the Sony logic is that you are not supposed to want to wind unformatted tape and then start the DAT and record without stopping. Thanks very much for any insights. My guess is mechanical damage to the tape. A good property of the SV3800 is that it has extremely good error correction and might be able to get you are better playback if it is really critical. The small Sony portable DAT recorders use a half diameter drum and may be able to play tapes that no other DAT can play. It is a great DAT you have, but the technology is fading. Transfer your recordings while it is up and running and start researching what recorder to get next. Mike Kind regards Peter Larsen |

Sounds to me like like your recorder needs either maintenance or different tape or both. It's probably beyond help from a cleaning tape and needs to be opened up and cleaned with the appropriate (not cotton Q-Tips) swabs and a liquid solvent. It may also need adjustment to get things running back in sync. Maybe even new drive betls and rollers. The thing about a digital recorder is that, unlike an analog recorder which shows degradation as it gets dirty or jerky, the digital process conceals the errors until it can do no more, and then you get a momentary data loss - which you hear as a click. So it can be working fine one day and the next little speck of dirt will push it over the edge and into real data loss. The way to diagnose it is to first try playing other recordings to see if they do the same thing. They may, even if your recorder is in good shape, because tape deteriorates, too. But if you can play another tape without clicks, then the problem was created when you made the recording. Data tape is sometimes a problem with audio DAT recorders. As Peter pointed out, it's thinner than what the audio recorder was designed to use, and that means that the tension, which is quite critical for a solid recording, will be wrong unless the recorder can adjust itself. The tape cassette has a pattern of holes that can be read by a deck, telling it what kind of tape is in the machine. A data recorder will detect the type of tape and the length and will set itself accordingly. Not all audio DAT decks read this code, however, so your thin tape may have been run with standard audio tape settings. I used to know a little about which DAT recorders could accommodate data tapes and which ones don't but I've forgotten that. If you can only find data tape now and can find someone who still works on DATs, you could have it adjusted to work with the tape you can get. It may just be time to bite the bullet and retire it, not because it no longer works right, but because the market for other recorers have made it obsolete. |

Thanks very much for any insights. Mike It doesn't sound like a tape problem to me - tape errors are usually much longer glitches of digital mash. A Dat system has a lot of reduncany built in, so much so that you can lose one of the two head outputs altogether and still be able to error correct to zero errors, so long as there are no errors on the tape. You need quite a largish chunk of tape to go wrong to be unrecoverable, and this does not usually manifest itself as the very short, spaced clicks on your recording. It sounds more like some kind of encoding error, a few dodgy samples, but this is a total guess. Are you sure the mic/phantom system is OK? Could there have been some odd static/earthing anomalies going on during the recording that upset the DAT and recorded short errors? Maybe someone walked on a carpet, got statically charged and touched the mic, DAT, etc? Gareth. |

Possible cause of clicks/pops on aging Sony DAT?
I have bought my Casio DA-7 portable DAT recorder in 1990. About 10
years later I've had to replace 37 (37!) electrolytic surface mounting (SMD) capacitors because their capacity was become about 1000pF(!) instead 1...100uF (many values). I have replaced them with non-SMD ones (bigger!), so I have solved the problem. The more critical capacitors are the ones in hot places, because they dry before the others. Before measuring capacitor I asked to the assistance: they told me that they had to replace the converters for more than 100$... Gianluca |

The 60 meter digital tapes are fine, and actually better certified than the audio grade tapes. My bet is the issue is the machine. These things need annual PM and a lot of them don't get it. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |

Possible cause of clicks/pops on aging Sony DAT?
Thanks everyone for taking the time to provide suggestions about the unusual pops and clicks that appeared in the output of my Sony DAT DTC-2000ES recording. Thanks especially Peter Larsen for posting the image of the click waveform at http://www.muyiovatki.dk/click.png It sure looks analog to me; I'm not sure if I should be happy or unhappy about that. Can anything be inferred from the fact that the click hit the two channels at different times? I suppose it is possible that one of the singers bumped or brushed by the mic / recorder, discharging some static electricity. But I can't remember seeing a static discharge last for so many seconds. Scott Dorsey asks what an error rate counter would show. I wondered about that, too. But because Sony marketed the 2000ES as a home deck, there is no error rate counter advertised in its documentation. I vaguely seem to remember hearing that some sort of magic key sequence would enable one, but have been unable to Google up a reference. Maybe someone else has better Google-fu than me? Or maybe I should pick up a cheap used pro DAT with an error counter. I purchased the machine used about four years ago. The previous owner told me it had been annually maintained, but he could have been full of hooey. I am a volunteer recordist on a budget, and I've only recorded about fifteen 2-hour sessions since then, so I have not had it cleaned or aligned while it seemed to be working fine. If it's time to get it done now, though, is there a local place in the NYC-Boston corridor I could take this, or should I ship it to Pro Digital? -- Mike --- |

I vaguely seem to remember hearing that some sort of magic key sequence would enable one, but have been unable to Google up a reference. Maybe someone else has better Google-fu than me? Or maybe I should pick up a cheap used pro DAT with an error counter. You have the very best mechanism available. The SV3800 has an easy access error counter and better playback error correction and needs both because the mechanism is somewhat less advanced, it is like the difference between a Beocord 1800 and an A700. I purchased the machine used about four years ago. The previous owner told me it had been annually maintained, but he could have been full of hooey. Not all people are bad. I am a volunteer recordist on a budget, and I've only recorded about fifteen 2-hour sessions since then, so I have not had it cleaned or aligned while it seemed to be working fine. If it was clean then, then it is clean now. That machine does not tend to suffer from any of the issues the SV3800 and similar primitive mechanisms suffer from. If it's time to get it done now, though, is there a local place in the NYC-Boston corridor I could take this, or should I ship it to Pro Digital? I know I contradict Scott on this, but is not likely to have a mechanical issue, it may however need cleaning, especially if a tape has flaked. It is awful to get loose debris clogging a head, however I know of people who have many more hours on such machines and the just work and keep working because there really is not very much that can go wrong due to the very few moving parts. I got tired of loosing recordings due to head clogging on my modded SV3800 (it has had a drive mechanism problem from new, unfortunately the mechanism was repaired rather than replaced) and bought a Fostex MR8HD. It does not sound quite as good, but it just works. Kind regards Peter Larsen |

It sounds like it was that way going in, and looks like it, too. No evidence of clipping or dropouts, and that's about all a digital conversion or storage process can do when you get down to a very close look. What happens when you record a steady tone? Or silence? You need to determine if this is something repeatable, repeatable under specific conditions, random, or just a fluke in this recording. |

I was thinking the same while I was lurking in the background, & listening closely, the clicks seem slightly off centre in the sound field, & sound almost exactly like rapid, distant gunfire. The first one sounds fairly heavy, with the rest sounding like small arms from half a mile or so. Is there a firing range in the vicinity? Cadet force practicing? It certainly looks on the trace & sounds like something external to the recording venue, IMHO. -- Tciao for Now! John. |

Not to appear contrary to the hoary heads full of wisdom, insight and advice to seek the most expensive and difficult course of diagnosis, but having spent way too many years recording singers in less than ideal conditions, I recognize this noise as purely mechanical/acoustical. It sounds exactly like a creaking choir riser, squeaky floor board, music stand hinge/pivot or some other mechanically generated noise that stopped when the perp realized it could be heard. ("Oh, cripes, I wonder if he could hear that?") You can hear the background room component of the noise. An anomaly with the recorder or tape would not imprint the room signature. Unless your sample has some kind of "room tone" added to it. Just my guess. "Stop. What's that noise? Can we get somebody to move around so we can find it? Okay, take two." TM |

Possible cause of clicks/pops on aging Sony DAT?

-- After looking at some DAT tapes I have on the shelf, contained unique historical recordings, and not willing to put them into any second-hand portable Sony or Aiwa, I came across a streamer SCSI device, Sony SDT-9000, which is capable to read/write audio DAT tapes. It's a DDS-3 device and it should be capable to read DAT tapes at some 2, even 3 times realtime. Together with the VDAT software, I hope I'll be able to finally transfer these, and a quantuity of similar DAT tapes. Sony SDT-9000 is one of very rare tape straamers, which may be reflashed with a firmware allowing them to be audio-DAT capable. I expect to get the streamer in 2 weeks. Of course, I'll test it with a blank DAT first. According to the seller, it should have been working for a short time only. Drooooool .... O;-) ... those drives are designed to handle much thinner tapes. But do not discard those portables, they can be better at syncing to problems tapes due to the small drum.

What makes you think this device would treat your tapes any better than a portable machine? Because it is built to handle thin tapes with care. The non-realtime option also looks nice. Kind regards Peter Larsen |

Dobro Utro Edi, I recall there being some concern if the portable machines had smaller diameter heads that the tape would be bent more as it wrapped. I am not familiar with this concern, but I have witnessed a small portable play a tape that was unplayable on five different statinonary DATs, including the one that recorded it.

Second-hand portable recorders are always risky -- it's a little problem when they eat up your new blank DAT tape but for these I have I must not allow this. Tape streamers seem to me safer especially when claimed to have low working hours. I have a TRAVAN tape drive and never experienced a problem with a tape (way back when I have been still using it). So I expect this device to be safer to DAT tapes as well. It should have error correction and I can have recordings at least 2x realtime directly to the SCSI bus. For my purposes, professional DAT recorders in a maintained condition aren't necessary. Edi Zubovic,, Crikvenica, Croatia Dobro Utro Edi, I recall there being some concern if the portable machines had smaller diameter heads that the tape would be bent more as it wrapped. DUnno. Regards, Ty Ford --Audio Equipment Reviews Audio Production Services Acting and Voiceover Demos http://www.tyford.com Guitar player?:http://www.youtube.com/watch?v=4RZJ9MptZmU Dobar dan {Good Day} Ty, I wouldn't have nothing against a brand new portable DATdevice. However, as on the Ebay we are often buying "the cat in a bag" ie. unproved things being carefully advertised and photograhed -- carefully to the seller, that is -- I had to screen out the portable DATs which may have been broken, serviced, dropped down etc., as I'd like to reduce the risk of damaging a tape to a minimum if possible. All the best, Edi Zubovic, Crikvenica, Croatia |

diameter heads that the tape would be bent more as it wrapped. DUnno. Regards, Ty Ford The DATs with the smaller diameter heads have to have the tape wrapped round far more of the heads circumferance than a standard head, meaning, IIRC, increased friction between head and tape, and therefore more likelyhood of a sticky head snatching the tape and eating it. There were other issues too, can't remember them now. (head gets hotter?) Gareth. |

Edi Zubovic, Crikvenica, Croatia Hello all, today I've received the Sony SDT-9000 and after installing it, I can say that it fulfilled my expectations. It seems to handle the tape very well, with the VDAT software I'm able to transfer recordings at approx. double speed (SCSI sync it at 10 MB/s, 8 Bit) and I couldn't find any error, glitch or whatever. The recordings sound excellent (first-gen production master tapes) and frankly nobody could tell that they were recorded more than 50 years ago. The reel to reel machine has been optimally prepared for DAT recording. Of course, no processing other that standard ones (DC offset, dithering...) are required. Now that's about how Mobile Fildelity Soud Lab recordings recordings are sounding --Mono, of course. Edi Zubovic, Crikvenica, Croatia |

The reel to reel machine has been optimally prepared for DAT recording. You win, now I'm confused. When did the R2R enter this thread, has I overlooked something? - it is not admissible now if it was not entered into the thread at the first level.

Makes perfect sense, DAT tape as a storage medium is considerably "higher risk" than analog tape. The "2000" and the "77" are the best DAT's Sony made, but there are better converters around, imo even the "lowly" Audiophile 2496 is better sounding ex works, if possible do consider redigitizing with a high grade converter, I full well understand that all kinds of practicalities may hinder this with all the problems you have had in your region. Please repost what computer DAT drive you found usable .... Edi Zubovic, Crikvenica, Croatia Kind regards Peter Larsen |

Please repost what computer DAT drive you found usable .... Edi Zubovic, Crikvenica, Croatia Kind regards Peter Larsen The computer DAT which works well for transferring audio DAT tapes is the Sony SDT-9000 but only if it has been first flashed with the Version 12.2 firmware. Perhaps an adjacent version number (11.xx or so) has also the audio DAT capabilities but I have 12.2 and it works. Newer firmware will disable audio DAT feature so the drive should not be reflashed with latest Sony firmware. Also this Sony SDT-9000 is the one of three computer tape drives which is capable of handling audio DAT tapes. Here's the story:-- http://winkin.phpwebhosting.com/~firmflash/dat/ --I'm transferring the material with a program called VDAT. While I know that in the time the RTR to DAT transfers are made some 15 years ago, and A/D converters are now far better, it would be for now hard for me to arrange a repeated recording sessions, where I could record from a RTR to, say, the Sony PCM-D1. But today I've made a contact with the local recording label, which have that archive, to try to arrange for sending to me their project, a history of Dalamatian songs -- folk harmony singers mainly, either a capella or accompained with mandolin or other small orchestras -- which they issued on 8 CD (2 sets) and which has been made (very) substandard by use of that NoNoise system or similar. Now, I have an idea to send them a portable USB 160 GB hard drive, where they would put these _raw_ transfers (if they still have them) so I could restore them my way after I get the drive back. This is of course only an idea but it would be fine if this project would be redone the right way. But we'll see if this idea would come to some good ears... This are the only problem I have here, believe me Edi Zubovic, Crikvenica, Croatia PS. The recordings on DAT tapes I have are pristine and so they should remain... |
