Audio Master Quality Recording

Why “Audio Master Quality Recording” is inactive for Plextor PX-760A…

Because 760A don’t support “Audio Master Quality Recording”. This function is only for Premium2 CD-RW.

Simple.
Only the Premium2 has Audiomaster as an feature. All other Plextor drives are not supported.

Use GigaRec 0,9 setting and 4x speed burning. You will get results close to AMQR.

i think that this feature is only software limitation…

I master/remaster audio on the side in a semi-professional capacity. Trust me when I tell you, use a high-quality blank paired with a high-quality burner and limit speeds to 16x or under … that’s all the “Audio Master Quality” that is required in 2006. I have never issued a master for mass duplication that has been rejected because of BLER, and am consistently told that my masters far exceed most of the others that come in … which still generally also pass muster. I use Mitsui gold blanks in my Plextor Premium recorded at 16x. (24x would probably also be just fine, but I can spare an extra couple of minutes.)

“Audio Master Quality Recording”? Hype … hype … hype … Unless you’re one of those people who claims to hear a difference between 1x and 4x recordings, in which case you have bigger problems. (Like the black helicopters following you around, alien overlords persistently trying to penetrate the defenses of your tinfoil hat, sasquatch lurking outside your window, and your persistent inability to remember that the DaVinci Code is a work of fiction.)

There is always two sides to a story. In this case one is the burning part and the other is the reading part. Believe it or not but even in 2006 there are still readers out there that have problems with burned CD-R(W).

The point of AMQR (or GigaRec) IMHO really is to increase compatibility. Since this usually leads to less playback problems as a side effect it also leads to better audio (no or less skipping, for example). I have this one case of a friends car radio that will only accept CD-R with a Gigarec setting of 0.8x.

So is AMQR hyped? I would not think so. But it might be over-hyped because I rather see it as a very specialised tool in a narrow field of application. As you show in your example (and i totally agree with it) AMQR/GigaRec is totally useless when a decent burner with decent media and a decent reader are involved. However a chain is only as strong as it’s weakest link and i think it’s nice to have fix available for such weak links.

Just because you’re not paranoid doesn’t mean they’re not after you :wink:

kev99sl> Mastering with a Premium…
I used to make masters (private level) the last 3 years and let them press where a friend of mine works (professional, were they press for Sony and others). Discs not in the PMCD format were all rejected (including all discs written with any Plextor drive) or copied to a computer and were then remastered and burned with a PMCD capable drive for an extra fee. Since I have a PMCD capable drive I never had any problems of this kind. This applies to all pressing factories over here. The Premium as well as all Plextors except their professional one are not the best choice for mastering at all. But I think you already knew this.

I assume you refer to this: http://www.watch.impress.co.jp/av/docs/20021211/plextor.htm ? Is it still available?

Damn, whats that?

hwp> Yes thats the one. It is still available and it costs around 750,000 YEN (Todays rate 1US$ = 113.43 Yen)
Arrow> Plexmaster 01/02 (based on one of Plextors best drive the PX-W8220Ti) is a special drive made by Plextor for recording Studios. It is not available at normal stores nor have I ever seen one in action. It was meant to replace the Sony CDW-900E but actually it never did. I have read and heard many things about this drive and the critics it has got are not good. This is because it gets compared to the Sony CDW-900E which is said to be unbeaten till today regarding quality for mastering. Compared to the Sony CDW-900E or the newer models like the SONY CDU948S (well actually both drives are rather old ones) the recordings made with this drive are not as good as with the Sony drives, so the studios still widely use the 900E (here in Japan it is still kind of defacto standard drive for Studios and Pressing factories) for Mastering. Sony is still suporting it and TY and Ricoh still make Cd-rs specially tuned for the Sony 900E.
Plexmaster Specs:
SCSI Interface
CD-R writing: 8x,4x,2x,1x
CD-RW writing: 2x
PMCD capable
4 MB Buffer

All I know is what my clients tell me, and the last three houses that handled my masters had no trouble with my Premium-mastered Mitsuis burnt at 16x. For that matter, the AV production house that handles my (full-time) office’s work uses off-the-shelf Plextors and a couple of ancient NECs for all of their mastering. I guess when I start experiencing problems, I’ll start worrying.

Didn’t know that such a thing like the Plexmaster even existed. Thx for info! :wink:

How did you get PTP 2.33? 2.32a is the latest posted.

I guess its bundled with the latest PX-760A, but I’m not sure?! Could be, that haven’t had time to put it online :confused:

Moef

Bundle with the Plextor Premium2.

Ah yes, the usual BS and FUD from Our Man From Sony’s Cuckoo Land. And what is it in the so-called PMCD that the Premium cannot do? Let’s see:

  • E-32 error free
  • BLER of 150 or less

When you find media that the Premium will burn with C1 150 and C2s at 16X and lower, please let me know.

  • Disk-at-once mode
  • Single Session
  • 100% scratch free
  • Backed-up by client

Any drive can do that.

  • Accompanied by frame-accurate PQ Log sheet
  • Stored In A Standard Jewel Box

I don’t know what a PQ log sheet is, but no doubt it is paramount for audio quality. As well as the “Standard Jewel Box”. I doubt I could hear the difference between the same CD in a jewel case and a slim case; but of course, for someone who claims to tell one CD-R brand from another by their sound this must be easy as pie.

Never_Again I can see from your Post that you dont know much or nothing about Mastering Process or Pressing of Discs. You are right that this has nothing to do with Sound Quality at all but it is about the format in which discs have to be made if you want to have a real Master according to specifications.
PMCD is Pre Master CD and is still asked for by all professional pressing companies. It has nothing to do with sound quality at all. The only thing is that most pressing companies will do a copy to a disc according to PMCD standards if the copy you give does not comply to those standarts or reject it. So I wanted to say that mastering with Plextor drives is actually BS since it gets copied to a Sony or whatever PMCD capable Drive they are using. Also the PQ log sheet has nothing to do with sound quality either it is also something that is being used to press a CD. PMCD and PQ are also needed for data discs.
PMCD is Mastering information stored in an area after the lead out (to be exact the PMCD information starts at a point which is 1 min 36s after the Lead out and has to end at a point which is exatly 2min 0s after the end of the Leadout ).
Now the Mastering Information is:
For disc Information:

  1. Name of Company
  2. Record Product Number
  3. Master Disc Number
  4. Master Disc Production Date
  5. Others
    and for Subcode:
  6. P Channel Information
  7. Q Channel Information
  8. POS Code
    4)ISRC Information
    Now the Disc Information is:
    Basic Information:
    Byte Number 0-31 Name of Company (32 Bytes)
    Byte Number 32-63 Record Product Number (32 Bytes)
    Byte Number 64-95 Master Disc Number (32 Bytes)
    Byte Number 96-103 Master Disc Production Date (8 Bytes)
    And Extended Information:
    Byte Number 104-255 Memory Area (152 Bytes)
    Subcode:
    P Channel Information consist mainly of information on the start flags of each track and of the leadout.
    The Q Channel is 8 Bytes long and contains the information on:
    Control/Address
    Track Number
    Index
    Data Format
    Zero
    Absolute Time
    So now you tell me if the Plextor Premium can write this data to the area after the lead out.
    The answer is it cannot since it is not a PMCD capable drive. As you can see now there are MANY THINGS the beloved Plextor Premium CANNOT DO!!!
    And not to forget that you need Special software too since not all software can write to the area after the lead out.
    I never did say that it has to do with Sound Quality but wrote it because someone was talking about Mastering with Plextor Drives.

So now you tell me if the Plextor Premium can write this data to the area after the lead out.
IMHO any drive capable of RAW writing can write anything anywhere if there is no overburn prevention in the firmware … it would be totally up to the burning app to create the data that needs to be written.

The difference between drives which are able to write PMCD and those not is the ability to write the specific data to the area after the lead out (PM area of a Disc). I dont know why Plextor (Plexmaster and some very old ones can) and most of todays drives are not PMCD capable and I do not think that it would be very difficult to enable this feature.
Also PMCD does not conform to the REDBOOK standards.
Wincdr (yes WINCDR) can do PMCD writing in combination with the right hardware.
Also you need an errorcheck and Log after burning the disc to fullfil PMCD standards.
