I don't have much experience at all this so I'm wondering if I would get a better recording if I went from a DMP3 to a VTB-1 for vocal recording.

I'm presently feeding my SP TB-1 tube mic into a DMP3 into an RNC into a Korg D1600 DRS. I have my Trinity and Pa80 keyboards going directly into the D1600.

What I'm wanting to know is would I get a better recording if I put the DMP3 between the Pa80 and the D1600 and replaced it with a VTB-1 between the mic and RNC? In other words, would that be an upgrade for vocals or not? I would eventually get another DMP3 to use with the Trinity and D1600.

Thanks.

Tom

I think you'd probably get a better recording going from a VTB-1 to a DMP3.

You'll get better vocals from the DMP3. Hunt around this site for comparison mp3 files and you'll hear the difference. You might even hunt down one of the older voicemasters on ebay and it would better than the VTB1.

As a DI for instruments I would opt for the VTB1 over a DMP3 but not on vocals.
 
Shit, just toss a coin and take your pick . . . and use one, but not both. Your signal chain is getting a bit too cluttered, and you might consider cutting out some of your middlemen.

Keep your chains as short as necessary . . . and also try and minimize the amount of cheap toob pres while you're at it. You know the ones I'm refering to. :D
 
The VTB-1 uses an A/B discrete mic pre design and is quieter than the DMP3 (particulary at full gain), which use the same op amp as in the Mackie VLZ Pro series. The DMP3 sounds better than the
Mackie partly because the circuitry isn't as clean as the DMP3.

The "differences" in pre's you're hearing are probably a factor of;
1) MP3 encoding
2) Amateur engineering (especially mike placement)
3) Amateur performance

"Amateur" is meant solely in the context of knowledge and consistancy compared to established professional engineers and
performers. Any of the musician's who posted their MP3's could very well be extremely talented, so this isn't meant as a "dig" on their musical abilities, just reality.

Give me Pavarotti and George Massenburg for the shoot-out CD
and you'd have a much more reliable comparison! :)

P.S. The VTB-1 can be run totally clean without the "tube blend".

Wow, that's pretty interesting Chess. Since you seem to know so much about this, would you mind sharing some figures with us? How many db's worth of difference is there, and at what gains, and what equipment are you using to test this?

Just curious.

Hey, I'm just really excited that we have someone on this board who has such a thorough knowlege on this stuff, and takes the time to share the results of his exhaustive testing procedures.

. . . Kind of like when he went to a Guitar center and concluded that the Presonus MP20 couldn't hold a candle to his vtb-1 after talking in to it with one of their Mr. Microphone display models. That one convinced me right there to delete the "watch item" feature I had on an mp20 I saw on ebay.

I get all excited when people have that kind of technical experience to share with us -- it's like we have another Harvey, and I'm just taking my notes like a good student.
 
Hey Chessrock,
Have they changed your medication again? You seem more mellow than usual.
BTW, I just got a DMP3, and love it! Beats the heck out of that Bear/injure mixer I was usin'.
 
Hey, Chessrock,

Now you've got me really curious. What do you mean by "your signal chain is getting really cluttered"?

I have a LD condenser mic going into a preamp (required, won't work without it) going into a compressor (actually setup as a limiter because I'm not a really good singer and get overs without it) into a digital recorder. Where is the clutter and what should I do about it?

Thanks.

Tom
 
Chessrock, it's exactly 2.387645906537485983823676378438 dB
at full gain +-3dB @ 1kHz.

O.K., I confess it I used my EARS, and when I crank the dial for gain all the way up, the VTB-1 is quieter than the DMP3.
You busted me! :)

One more thing Chessrock,
don't EVER underestimate the "Mr. Microphone".
Remember the classic line "Hey good lookin', I'll be back to pick you up later"?
Works every time. (when I was single)

Chris
 
Hmmm.
Sorta surprised that Chessrock didn't respond yet.
So...

Just wanted to add that one advantage of a discrete based mic pre over an IC based mic pre is that the manufacturer can have more control over its operating system.
This was explained to me by a professional electronics person BTW, so it's not anything made up by yours truly.
It seemed a reasonable assumption that as Mackie and Behringer have used similar circuitry in the past (not sure about UB series),
when Studio Projects designed the VTB-1, they wanted to use the
discrete A/B design to perform at a higher level than those mixers.

In any case, yes I can hear the difference, although that's not to say with good "matching" microphones, that excellent recordings can be had with lesser performers than the VTB-1.

The "Mr. Microphone" was mainly the store's demo SM57.
It was a "nice" sounding one, not the best I've sung through, not the worst (yes they do vary somewhat in tone!).

In the future Chessrock, if you want to say anything with that kind of edge to it, feel free to PM me so we can discuss anything
you like in more detail. I prefer to praise in public, and (constructively) criticize in private when possible, unless blatantly provoked.

I guess they blew it.
 
I guess he doesn't want to tell me about my "clutter" either. HHmmmm. Oh well.

Look, I have nothing against the VTB-1. I think it sounds fine, and now that the price has dropped, I might even consider it to be a no-brainer if you're looking for a good-performing single channel. But there's still nothing to indicate it's a step above anything else out there in it's general price range -- particularly the Mackie and Soundcraft boards, the DMP3, etc.

Yea, I can be an asshole at times. Particularly on this thread, and for that I apologize. But I like this board, and it's important to me that we hold ourselves to some standards, here. Like for one, I think it's important, when talking about gear, that we at least try and speak as objectively and accurately as possible.

I'll give you a few examples:

Things like: "I've tried product A and product B, and have used both on several sources at both higher volumes and lower volumes, and to me, product A seems quieter to my ears. Particularly at the higher volumes." -- This kind of statement seems legit to me, provided you have that kind of experience with both product A and B.

Here's another, even more honest and objective view: "I've never worked extensively with product B, but I own product A, and from what I've read about product A's design (from RAP, Gearslutz, etc.), they tend to be quieter, particularly at higher gains, than those with product B's design. Also, I happen to like the manufacturer of product A, and I think they make great microphones."

These are the kinds of statements that can help keep our board free of bullshit . . . and free of the need for guys like me to be assholes.

When you make blanket statements like "Product A is quieter than product B, particularly at higher gains," you are moving away from opinion territory, and are now talking about objective, tangible, measurable figures. And I'm sorry for being an asshole, but I think we should all be careful about these things before we go throwing them around lightly. Do your best to check them out first, because they could be wrong.


Now as far as the whole discreet versus chip, a/b versus a versus whatever . . . none of that stuff really holds a lot of meaning at the $200 and under level. Simple, well-implemented chip designs can be much quieter and will spec even better than some of the more expensive discreet designs. etc. etc. etc. I'm sure we're all aware of just how meaningful specs are in the scheme of things -- if we were to base everything on specs alone, then the Mackie board would probably kick ass over the API's, Tridents, etc. Not to mention the tube and transistor-based "color" standalones. --On specs alone, mind you.

That being said, I can't think of too many pieces of equipment I've ever worked with that are as quiet as the M-audio stuff. Particularly at higher gains, and I'd bet if you put it up against the most expensive stuff out there, it would hold it's own. Now, as far as it being linear at the higher gains -- that's debatable. And let's not get started on it's headroom, and what I'm assuming is likely a sluggish slew rate. :D (To qualify, these are measurable figures, which I am going purely off of what engineer-types have said about them, so don't quote me).

But the damn thing has got to be about one of the quietest things out there, which is why I was so curious as to how you derived your conclusions. I suspected they were opinions based on very little experience as opposed to factual, so I called you out. In the furture, to avoid conflicts, let's try and qualify things before we throw opinions (and, in this particular case, guesses) out as facts.
 
Apology accepted Chessrock, thanks.

Being an individual who openly admits his enthusiasm far outstrips any "expertise", it's understandable how my relatively
unabashed support for the VTB-1 could appear overboard.
This is mainly a function of personality type.
Maybe we could put it at the botton of my posts, like a "Surgeon General" type warning.

I think you're right that the first two statement "style" examples you gave are normally most appropriate for someone like me.
The personal tendency to seem arrogant is mostly enthusiasm
mixed in with a streak of competiveness.
(many years of tournament chess reinforces that too!)

My main concern in these types of discussions is that we're not squelching the spirit of someone here at this BBS by getting
too "personal" in terms of interrogation-oops I meant
questioning. Who knows, they could be the next George Martin!
If we're supportive to them whether they make mistakes or not
that keeps learning fun. Uh-oh, starting to sound like an infommercial. :)

Chris

P.S. Tomcat, "clutter"-meaning it's (normally) best to minimize the
signal chain to have a cleaner recording.

I misread your question. I thought you were saying you wanted to go from a dmp3 in to a vtb1 as an addition to your signal chain (and thus chaining two pres together). :D My bad. In any case, I don't think it's an upgrade. You're talking about two good pres in the under $200 price range, and I doubt you'll hear any difference -- untill you start getting in to Grace Design territory, perhaps.
 
Wanna know something cool?

The VTB-1 is 129 US in the US, and it's 500 Canadian in Canada.
That's about 340 US dollars.

WTF?
