Mic & Preamp Suggestions?
I'm a little disappointed with my combination of Grace 101 microphone
preamp and AT4033 mic. I'm not sure which is most at fault, but I find that I have to turn the volume waaaay up on the pre-amps to get any appreciable amount of signal from them, and the noise then goes up similarly. Any of you have any suggestions for low-noise mic (preferably condenser) and preamp for "close in" recording of individual instruments and voices, the voices being mostly spoken narration. -- (Preferably reply to the newsgroup, please.

Sounds to me like something is broken along the way -- normally, even with a soft spoken voice this combination should give you PLENTY of clean signal. (Hell, the last time I had a 4033 into my Grace 801 I had to use the 20 dB pad and turn the gain down quite a bit -- true, it was a singing voice and not a spoken voice, but we're talking 50+ dB of attenuation below the max gain that the chain could provide. And it sounded great.) Have you swapped each element in the chain? Mic? cables? Some other pre? What are you feeding this into, and how is that component set up? Was this combo fine at some point but recently doesn't seem right? How are you monitoring? Etc, etc. Many things to methodically check. Frank Stearns Mobile Audio -- |

How are you defining "appreciable amount of signal?" How are you measuring it, and what's the next device in the chain after the preamp? You might be making the common beginner's mistake of not leaving any headroom and trying to make everything hit the top of the meter scale. Or you may just not have gains adjusted properly throughout the system. An eyeball average of around -20 on a digital meter is a perfectly acceptable recording level, particularly if you're recording 24-bit data. 20 dB more gain that what it takes to produce that average level will produce audible hiss on just about any system. So unless your mic or preamp is actually broken, it may be that you're the one causing the problem. Any of you have any suggestions for low-noise mic (preferably condenser) and preamp for "close in" recording of individual instruments and voices, the voices being mostly spoken narration. What you already have should work just fine for that. |

The 4033 has a switched 10dB pad. Make sure it's not engaged. If the pad is off and the problem persists, then re-read Mike's post carefully. |

Mic & Preamp Suggestions? A related thought....
This is a little off-the-original topic, but something I'd been thinking about
and wondering how I should ask the question - or if it should be asked at all. I've read postings here previously that mentioned that the sound of a mic had a great deal to do with the preamp that it was attached to. No problems there, completely understandable. If that's the case, then I would think that there are _some_ mic/preamp combinations out there that, for whatever reason, just seem to work especially well together. On the recommendation from folks here, I picked up an FMR RNP and it's been a good purchase for me. I use it with a couple of mics (CAD M-179 and Audio Technica AE5100), and they work OK to my aging and untrained ears... but... For those who have used the RNP, have you happened onto a mic here or there that seems to work particularly well with it? The mic/RNP combo will be used for male vocals and acoustic string instruments (guitar, banjo, mandolin). I don't really have the luxury of being able to "audition" various mics; guess if I _did_, I wouldn't have to ask! Thanks, - John |

Mic & Preamp Suggestions?
First of all, thanks for all of the replies.
Second, I apologize in advance for the rather long posting here! Here's a little more information on the setup: 1. I just now bought a second copy of this setup, and was disappointed find it to be noisy, by which I mean that it has a fair amount of electronic, tape-like background hiss (actually, I think it's a little more broad-band (white) than the blue-noise of tape hiss). 2. I tried it along with the original mic/preamp setup, and found it to be pretty much the same. I hadn't used that first setup for quite a while, so either I'd forgotten how noisy it is, or my ideas of what constitutes a noisy setup have changed. 3. I noticed, however, that the volume knobs on the preamp were in fact set to a very high volume from when I used it last. 4. The original mic seems very slightly louder (signal and noise) than the new one. Otherwise they seem to be producing pretty much the same results. 5. I tried disconnecting the mics from the preamps (at the mic end of the cable) and turning the volume on the amps all the way up high. There was some hiss, but all in all, it was fairly quiet. 6. I then wrapped up one of the mics tightly in a large bathrobe to try to block as much sound from it as I could. Speaking intuitively (I don't have a dB meter), that probably increased the overall noise by a factor of 4 or so. 7. Unwrapping the mic, the noise (presumably due to air circulating in the room) probably increased the overall noise by a factor of 2 or so. 8. The "rest of the system," during this experimentation, consists of a Yamaha integrated amp (a high-end home model from probably 8 years ago), listening through decent-grade Sony headphones. The volume of that setup is set to where music from a CD player instead is at a reasonable listening volume. 9. The 10dB pad switch that "Agent 86" mentioned is off, as is the low-cut. From that experiment, it sounds like the potentially biggest culprit is the microphones or their connections to their preamps. Given this new information, the most especially interesting comments I heard from you folks seem to me to be: 1. "This combination should give you PLENTY of clean signal" (i.e., Mr. Stearns reports having gotten good results from this same combination. However, I have a Grace 101, whereas he reported using an 801, which I gather to be an 8-channel version of my 101, with similar specs, correct? 2. "How are you defining 'appreciable amount of signal?'" Well, that's a good question and some related questions include: "how close to the microphone?" and "how noisy is 'too noisy'?" Here's what I can say about those questions: a. My immediate assignment is to create a CD consisting of only two voices in my studio, so I'm comparing those results to a CD of a vaguely similar setup: A violin solo with piano accompaniment. b. With the preamp volumes at maximum and the power amp at the same level, my voice sounds a little quieter than the violin in the recording, with my mouth about one foot from the microphones, and the background noise level is probably about twice what I hear in that professional recording. Does that sound like what I should expect? It seems like I should expect a lot better S/N, and I shouldn't expect to have the pre-amp volumes set so high. 3. "Try another cable": When it comes to hiss (as opposed to hum), I'm not sure right off how the cable could affect things, unless it's wired wrong, so that the amp is differencing across the one of the inputs and ground rather than across the two differential inputs. I ohmed out the right mic's cable, and it reads as a "straight through" cable, with a fraction of an ohm between the ends and no shorts between any of the leads. So, waddaya folks think? -- (Preferably reply to the newsgroup, please. If you reply by Email, I will sincerely try to receive your message, but it will probably get buried in spam.) |

And comparing this to the volume of a CD? The CD may have been processed to death to optimize it for volume and your mic has not. I think that you need to make some measurements. You say you want to record a CD, so you must have a recorder. This can be a real recorder, or more likely these days, a computer equipped with a sound card of sorts, hopefully a more predictable and controllable one than the one built into your computer. So what do you have that you can use for a real world test? -- I'm really Mike Rivers ) but you can't send anything larger than 30K to that account, do don't try. |

Disagree strongly. The NT1-A is a very natural sounding mic. What it lacks is the upper mid hump which many seem to regard as giving a mic "character".

In particular, it's one of the demonstration recordings for Suzuki violin students (yeah OK, sounds strange, but it's something of vaguely similar nature I happened to find sitting around). I do have various means to clean up the sound further, such as various plug-ins to Digital Performer. As we all know though, such widgets almost always work better if they're used very sparingly upon sound that is already as good as we can realistically make it. -- (Preferably reply to the newsgroup, please.

That could be a good call, Gary. Like several of us have suggested, unless something is _wrong_ that pre and mic shold not be bothering you with noise. But if there is any noise at all to speak of in that room, and you open up that preamp with that mic hooked to it, you're going to get loads of noise in the tracks.

That would make sense given your situation. I just made a quick sound check with an AT4033 into a Sound Devices 702 and the residual noise level is greater than 70 dB below the voice envelope peaks. Most of that is my room noise. The mic and preamp self noise are much lower still. bobs Bob Smith BS Studios we organize chaos http://www.bsstudios.com |

Mic & Preamp Suggestions?
Much to my surprise, I think this is all just a big boondoggle!
I decided to go forward with the recording itself, assuming that I can correct the problems with various computer widgets and such. I'm still not completely sure why, but my experiments that suggest that there's a problem just didn't correspond to the reality of doing the actual recording itself. During the actual recording session, when I did the preparatory sound checks and such, the volume went down to about where I would expect it, the noise level was reasonable, and so were the signal levels. So, in short, I don't think it's a problem after all. Thanks again for the suggestions and ideas. -- (Preferably reply to the newsgroup, please.

You are sugesting a setup that is a significant downgrade all 'round. Hi Hank, good to hear from you again. I have to disagree. The OP was principally concerned about noise. For starters the AT4033 has a self noise of 17dB SPL and the NT1-A has only 5dB SPL, in other words it's 12 dB quieter - hardly a downgrade. I mentioned the dbx 286A simply because I have direct experience of it with the NT1-A and I know the combination exhibits extremely low noise even at high gains. Ian |

Gary Morrison wrote: FWIW, my current guess is that a substantial part of it comes from underestimating how much room noise I have. That's clearly nothing wrong with the mic and preamp, but you can easily determine this by setting up the mic, setting the gain to where you need it in order to get a good recording level, and record some "silience." Then listen to what you have. If you hear a constant hum or buzz, this indicates that there may be a problem with a cable, or (less likely) a problem with the mic or preamp. If you hear any recognizable noises like a furnace (or air conditioner if you're in that part of the world) fan, a computer fan, traffic, kids playing in the yard - that's a problem with room noise. You don't need to measure the noise level so much as to determine the character of the noise. Maybe you could put a short sample up on a web site for those who want to listen to it. But you should try to measure signal levels to make sure that you don't have, for instance, a low level coming out of the preamp and need to boost the gain of the A/D converter in order to get the signal level up, then you'll be amplifiying both room noise and any electrical noise. If you can get the desired signal (voice, piano, etc) well above the level of the room noise by moving the mic closer, you'll improve the signal-to-room noise ratio. |

Gary Morrison wrote: I decided to go forward with the recording itself, assuming that I can correct the problems with various computer widgets and such. I'm still not completely sure why, but my experiments that suggest that there's a problem just didn't correspond to the reality of doing the actual recording itself. During the actual recording session, when I did the preparatory sound checks and such, the volume went down to about where I would expect it, the noise level was reasonable, and so were the signal levels. This is a common "beginner" problem. You think you should test out your system (always a good thing) but you don't realize what you're actually testing. You turn up the gain or monitor volume until you can hear a problem and then think you have a problem. But then you find, as you have, that in practice you can't use that much gain for what you're recording. |

Like Ty keeps saying, the mic and the pre constitute a system. Yes, when used with the wrong preamp, the TLM 103 can be wrong, but still righter than an NT-1a 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 |

Proceed to the Neumann TLM 103 which has lowself noise and sounds good. The TLM103 has Neumann's classic center-terminated capsule. The NT1A has an edge terminated capsule, as is also found in Neumann's newer designs. The center termination, which pins the diaphram at the center as well as the edges, results in resonant behavior more like a smaller diaphram. I wonder if this could be the primary cause of your preference? Bob Morein Dresher, PA (215) 646-4894 No. It's getting the right mic plugged into the right preamp. I was finally able to get this info into the microphone chapter of the (rather large) NAB Engineering book this past issue. The world will be a better place.

Ian Ah, yes, well you're not taking into consideration the sensitivity of the mics. The TLM 103, I think, is more sensitive. As a result, you have to boost the NT1-a up to where the selfnoise is more evident. The again, if the mic sounds nasty, who cares about selfnoise.
