Inline attenuator for vocals?
For vocals, I use a Rode NT1 and have a groove tubes brick preamp. I have a powerful voice, and no matter what I do, my louder vocals always seem to distort. I've tried lowering the gain, and also have stood further away from the microphone. I’ve also tried changing the ground signal switch, and have used different cables and inputs (XLR or line). I'm thinking that I should try an inline attenuator, but would this negatively impact the sound? Also, where would this inline attenuator go? Would it be between my mic and the preamp, or the preamp and the recording box? I believe it is my preamp that is actually distorting the signal, not the mic, because I plug the mic direct in the XLR with phantom power and do not distort. I have been doing vocals this way, but miss the warmth and tone of the Brick. I've seen a model made by Audio Technica (AT8202 Adjustable Inline Attenuator) for $40, and it seems that it may work, but I have no idea what the quality is. I only would need this for singing. I wouldn't need more than one channel. What might you recommend? Do you know of anything that lowers the volume between preamp and recording box? If so, is this a bad idea?

Does the Brick have a Pad? Many mic pres do. Engaging it would typically lower your incoming vocal by about 20db.

The mic may have a pad. But the best thing to do is just back off the mic and raise the preamp gain. It is art, not science, trying to get the distance right between a loud singer and the mic. It doesn't help if there is a large synamic range too - whisper to shout. If you recording yourself you can't "ride" the levels, so you have to pick a happy medium. Also, I'm sure you are like every other performer and during a live take raise your volume just a little. Adjust for that beforehand as the engineer. The brick doesn't have a lot of gain, but it should be able to handle hot signal from your mic. You might want to make sure your room is treated, too. But the brick is a good preamp. @

That's something I forgot to say, neither mic nor preamp have a pad. I have tried standing away, but as a singer, I find it hard to work the mic once I get more than a foot away. I also sometimes found myself pulling back and affecting my performance so I didn't distort. This of course was not good either. It seems an attenuator is sort of a lame thing to try, because it would defeat the purpose of the preamp. Yet, presumably, I would still get the Brick's coloration. I think I'll try this method, but there are certainly no guarantees that it will work. It also may screw up the sound and add noise. I also thought of an external compressor, but that may get rid of some of the nuances of louder vocals. Also, who knows which one to get? There's also a learning curve, and such devices can be pricey. I don't know what singers like Eric Burdon or Van Morrison had in the 60's. Maybe analog was better for loud voices. I am not a metal singer, but how on earth do they do vocals without clipping?

If you feel kind of lonely staying away a foot from mic maybe a pop screen on a separate stand would make you feel better. Something to grab maybe. You do use a pop screen, or? It will help taking away some edges of highest amplitudes as well. Tubes add distortion, you know that I guess, and what you call warmth is actually even harmonics which is distortion. So maybe you just wind gain up too much to get that 'warmth' you want. Clearly away from peaking there is less distortion and warmth as well. And for tube preamps in this pricerange you should not expect too much. You need saturated tube to get warmth. But tubes does not only add even harmonics, there are odd as well, and these are causing the harsch part of sound. Especially on cheap pre amps. So a better tube pre amp might be what you are looking for, if not succesful with another stand.

Yea, it is a real pickle. Performance and tone seem to be contradictory. I like lfm's suggestion about a pop screen on another stand. Or simple discipline - pick a spot and stick with it distance wise. If you don't get the tone on the quieter spots, do a second take. Skip the loud passages, get close to the mic, reset the preamp volume and do the lower amplitude sections, splicing them in. The other thing might be a preamp with more gain - the brick doesn't have as much as some others. The focusrite has 80 dbs of gain, a nice input transfomer for tone and lots of headroom so you won't distort. It is cheap these days - $500 or less. Or get the RND Portico II channel strip. I guarentee you'll blow your diaphram out (either yours or your mics) before you distort it. I'm sure the Aurora and any number of professional kits would work as well, but you are talking real money. @

I would just use a different mike! Every singer has the right match and just because a mike is a so called good mike doesn't mean it's the Right mike. You can actually distort the mike. Padding down the signal will not help if you have overdriven the the mikes electronics. Getting away from it will work but that is not a good idea. The sound can become trashed. Like you say , you need a mike you can work. It's a hard job, but you need to get your hands on a many mikes as you can. Then find that one that works for your voice.

I guess there's no easy solution, lol. I do have the ability to stay in one place when singing in the studio, so I guess that is good. It may just be that I have to keep doing multiple takes and punch. Not fun, but I definitely have experience with this.... johnnyV Padding down the signal will not help if you have overdriven the the mikes electronics. What if the mic isn't overdriven, and it is the preamp doing the overdriving? Is it okay to attenuate the signal going into the preamp then? I'm pretty sure it is the preamp and not the mic, because I plug the mic directly in with no preamp and do not distort.

I mentioned this just on the off chance that it might happen. seems not. Specs shows: Maximum SPL 137dB SPL (@ 1kHz, 1% THD into 1KΩ load) So I doubt if your singing is that loud! That's loud! I looked at the pictures of you pre amp, Now I see your problem, It has no pad and no peak light?? My guess is putting a resistance in line could possibly work but personally I would look for a pre amp that was better suited to match your mike. If that one is over driving at the lowest setting, then it's a miss match. Either that or it's a bad design thus the distortion. There's no way you should have to add even more attenuation than what's already supplied in the design. That's changing the signal impedance and might have an effect on your quality too. So I'm not sure if it's a good idea, try posting on gear sluts there's lots of good techies over there.

I would expect that you'll need to use a pad/attenuator with the brick. The brick provides 25db gain on the MIC input with the gain all the way down (fully couter clockwise). That's a good chunk of gain at the lowest possible setting. I wouldn't hesitate to try the attenuator - that AT8202 is probably a good choice since it is adjustable -10/-20/-30 DB. You'll probably be in for a bit of mucking around to find your 'sweet spot' to get the preamp warmth without any overloading. Let us know how things turn out. Cheers - Cliff
