phantom power?? mic preamp??

Ok. I've been reading posts here and am confused by xlr and 1/4" jacks.The only xlr microphones I was familiar with was a couple of old electovoice studio mics and worked fine in an old compatible PA system.When we upgraded back in the eighties eveyting wanted 1/4" jacks. These were low impedance microphones and needed line transformers to boost the power for these newer amplifiers. All our high impedence mics with 1/4" jacks worked fine. That might not have really been much of an upgrade. There were a lot of those PA "heads" around in the 80s (and 70s & 60s). Sometime in the 80s you started seeing both XLR & HiZ 1/4" inputs. While not truly "Pro" units, they got the job done. Many are still in service, like my PV XR-400b, which still sees regular use. Most condenser mics require phantom power.Does a mic preamp supply phantom power? Many condenser mics require phantom power, and most decent ones do. Phantom usually comes from the preamp (or the built-in preamp on the mixer channel), but there are stand alone power units if the preamp doesn't have phantom, or doesn't provide enough voltage or current. My recording unit wants 1/4" jacks. Would xlr to 1/4" line transformer suffice? Depends on the recorder. You need to check the manual. Some cassette decks & older reel-to-reel units have 1/4" mic inputs, but my guess is you're looking at 1/4" TRS line inputs. If that's the case, you need a preamp between the mics & recorder. I stopped in at Long & McQuade and if I could purchase a couple of those md 421's listing for $499.00 Can. I wouldn't be asking these questions. Markertek has them for $319. Full Compass is probably a little cheaper. They're nice mics, but I'm not sure how you think they would be the answer to all your questions. I am not sure that I can get enough gain on my mt-400 to even satisfy the 200 ohm impedence rating of even these. I'm not sure what a mt-400 is. Gain & mic impedence aren't directly related. I am recording a choir accompanied by a keyboard, piano, 6 & 12 string guitars and bass track added later. I have two cheap dynamics and would like to add a large diaphram condenser such as marshall 770, apex 430 or oktava 319 in a decca tree config.Can this be done with reasonable results for around $200.00. Can what be done for around $200? Recording a choir, keys, guitars & bass? Probably. Buying a decent large diaphragm condenser? Probably not. Getting a good recording od a choir & varoius instruments with two cheap dynamics & a cheap large condenser on a Decca tree? Maybe, but it wouldn't be my preferred approach. Good luck. It might help if you could clarify your questions just a bit. |

That sure doesn't sound like an upgrade to me. That definitely sounds like downgrading to cheap consumer gear. Most condenser mics require phantom power.Does a mic preamp supply phantom power? My recording unit wants 1/4" jacks. Would xlr to 1/4" line transformer suffice? Most preamps today will supply phantom power. If your mike requires phantom power and your preamp does not supply it, you can buy an external phantom supply. If your input is high-Z, you will also need a step-up transformer.

I am not sure that I can get enough gain on my mt-400 to even satisfy the 200 ohm impedence rating of even these. They are not condenser microphones, and therefore do not need phantom power. You will need a step-up transformer to drive a high-Z consumer input from the 200 ohm source. In the seventies, Sennheiser made a mike that used an element similar to the 421 with a step-up transformer inside for a high-Z output. It was very popular for ham radio operators in Europe but I have not seen one in years. I am recording a choir accompanied by a keyboard, piano, 6 & 12 string guitars and bass track added later. I have two cheap dynamics and would like to add a large diaphram condenser such as marshall 770, apex 430 or oktava 319 in a decca tree config.Can this be done with reasonable results for around $200.00. Well, none of these mikes will work in a Decca tree configuration. Why do you want a Decca tree to begin with? Why do you want large diaphragm mikes for a choir? Are you willing to buy a real preamp with normal XLR inputs? --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |

Say hi to agent 99 for me. But, back to my question. First though a little clarification. This recording is strictly a hobby and the recording is for posterity. Prior to my joining the group the recording was done on your regular ghetto blaster with internal electret mic. I borrowed a tape, put on headphones and thought I'd give it a listen. Ouch!!!!! It sounded like someone recording heavy machinery at work. There was also some voices in the background but not distinguishable. so, I brought in my Yamaha mt-400 multitraker with two cheap dynamics and that was a giant leap forward. So much so that two other groups have expressed interest in being recorded. I would like to improve clarity and detail and was leaning towards a condenser studio mic. I would like to continue using my porta studio for live recordings but my microphones need to be upgraded. Should I move toward better dynamic mics or toward condenser? Would a pair of sm-58's do the job? OK, I checked Yamahas site & it looks like the MT400 has the old style 1/4" Hi-Z mic inputs. So to use Low-Z mics, you will need a transformer. The Shure ones are better than the Radio Shack ones, but they do cost a bit more. Alternatively, you could use an outboard preamp & go into the Yamaha's line inputs. If you get a decent preamp, this will probably be a big sonic improvement, but a decent preamp will cost a good bit more than the Shure transformers. If the budget allows, look a something like a Mackie 1202 VLZ or the Behringer equivalent. That's as much preamp as you'll ever need for a cassette 4-track, & it'll still be usefull if you switch to digital later on. Now regarding mics... Assuming the "cheap dynamics" you have are not capable of doing the job, my stock advice to anybody looking for their first mic is to get an SM57. For your second mic, if you need to do realtime stereo recording, get another 57, otherwise, consider an EV 635a. These will set you back less than $100 each & will cover a lot of ground. All things being equal, you are correct in thinking that condenser mics will have more clarity and detail than dynamics. But, of course, all things are seldom truly equal. There are a plethora of cheap condensers on the market these days. Many of them suck. In the long run, you'll get more mileage from a good dynamic than a cheap condenser. But you want to record a choir, & that throws a spanner in the works. Dynamic mics typically have lower sensitivity than condensers. Plus, they don't usually have much low end when micing distant sources. So, you just might need to get yourself one or two SMALL diaphragm condensers. I've been using AT 4051s & I like them a lot. They're not Neumanns, but their not exactly budget either. A lot of folks around here like the Marshall 603s & the Oktava MC012s (get your Oktavas from the Sound Room, because Oktava has some consistency problems). The new Rode NT5 & NT4 have been mentioned favorable as well. I won't make a recommendation for any of these mics, since I haven't used them. Hopefully, some other folks who have will chime in. If you can fit the 4051s into your budget, I'm sure you'll like them. I'd advise you to wait about a large diaphram condenser for a while. By design, they are not consistent off-axis, which limits their usefullness for choirs & such. And everything I said about cheap, sucky small condensers goes double for large ones. You'll probably want to get one (or more) later on, but if I understood your question, you're looking for maximum versatility at this point. As far as 58's, you probably wouldn't be happy with them as your only mics. The big wire mesh & foam ball does some wierd stuff to the frequency response & makes them not very suitable for most instruments. I like them on guitar amps now & then, but you'll find the 57s are much more versatile (and cheaper). |

Wow... now you're talking my lingo. This is great info and gives me some direction without having to dump a few grand into recording equipment. Not that it would break me but would definately put me in the doghouse.(wife wants new floors in the house) . That's two in favor of small diameter condensers so I will definately check this out. I also like the sm57 idea as they will never go to waste. I want easy portability. Thanks again and now I have some homework to do.

Ok. I've been reading posts here and am confused by xlr and 1/4" jacks.The
only xlr microphones I was familiar with was a couple of old electovoice studio mics and worked fine in an old compatible PA system. I have never seen any microphone without XLR. How would you even have a 1/4 plug on the butt end of a microphone? How would you connect a mic cable to it? Unless you are referring to old tape recorder microphones that cost around $5, it is puzzling where you find mics without XLR connections on them. When we upgraded back in the eighties eveyting wanted 1/4" jacks. These were low impedance microphones and needed line transformers to boost the power for these newer amplifiers. "low impedance" does not mean it puts out less "power" than high impedance microphones, it just means the IMPEDANCE is lower, which is a good thing. Thus why you don't see any professional "high impedance" microphones anywhere. Most condenser mics require phantom power.Does a mic preamp supply phantom power? My recording unit wants 1/4" jacks. How the hell are you going to get phantom power with a 1/4 jack? (considering you are probably talking about 2 conductor 1/4 jacks here anyway) I am recording a choir Why doesn't this surprise us? guitars and bass track added later. I have two cheap dynamics and would like to add a large diaphram condenser such as marshall 770, apex 430 or oktava 319 in a decca tree config.Can this be done with reasonable results for around $200.00. To record a choir, you don't need more than a $10 tape recorder with a free mic included. |

I'm still following this thread and thought I'd update where I'm at. The
635 and 57 are out. I felt that going this route will only give me more of what I already have. Will go the route of the condensers with a mackie preamp but am leaning toward a behringer mic2200. What are your thoughts here? Now I need to decide if I can go with one condenser and use my pair of dynamics to record three tracks or to go with a stereo pair on two tracks. If one then I will likely go with the 012. A matched stereo pair of those Oktavas with shock mounts is fairly pricey for my budget. If two, will likely opt for the 603s's. Would like some input here. And if "truth" is still out there...... believe it or not, they do make an adaptor that sticks on to the butt end of an xlr microphone and you can just plug your instrument cord right into it like you would a guitar.

If you only need two channels of mic preamp, & you really want Behringer, get a UB802. The pres are decent. You don't get inserts or direct outs, but the signal path's so short it won't matter much.

Personally, I'd try an ORTF of XY first. That way you can use cardioids (so you can go with the 603s & stay within your budget). If you spend some time experimenting with placement, you'll probably find something you like. Shine on the shock mounts for now. Just tell everybody to be still during the take. Or make your own with some stout rubber bands & 2" PVC plumbing parts. |

It is designed to convert a low impedance signal into a high impedance signal. If you really need a high impedance signal, it would be better to run the low impedance signal from the microphone through a regular mic cable and leave the impedance transformer as close to the mixer as possible. You can't really run a high impedance signal at mic level for more than about 20 feet without noticable degredation or noisse pickup. I have also seen microphones with a 1/4" jack on them. They were supplied on a cheapie lecturn amplification system. Richard H. Kuschel "I canna change the law of physics."-----Scotty |

Ok..... I.m sold. The ub802 it is. And the pair of 603s's. I tried the
decca tree thing and didn't like it anyway. Basically muted the center channel out during the mixdown trying to get some definition and at least a semblance of stereo imaging. We don't have three ears so why confuse the brain into trying to decifer impossible acoustics. Now.... about those dynamics....er..uh.... (this is embarassing)... they are the no name brand of sm58 wannabe's that come packaged with those $150.00 karaoke machines that they have been churning out by the thousands. And that fake toob thingie. Maybe I should route the signal through my old traynor bass head. Lots of real vacume tubes in that baby. What would be the point of warming up the sound and then freezing it to digital. Anyway, thanks loads Scott, Paul and Max....er.. Agent 86. "agent86" wrote in message ...
