    Hello All !!!
    this is my first post on this forum, and i need HELP
    i'm looking for microphone capsules (condenser or dynamic) to amplify my instruments (Guitar, Accordion, Viola, Dulcimer ...) on stage.
    microphone capsules will be connected to SHURE PGX1 Bodypack Transmitters

    in my country we have the opportunity to shop from Mouser.com

    PLEASE .... help me choose good quality and low price (up to 10$ per unit) microphone capsules from Mouser

    Thanks in advance

    You are not going to get much in the way of quality at that sort of price level. I assume you are talking here about small back-electret condenser capsules.

    If you were to buy a capsule, what are your capabilities when it comes to design, mechanical construction and electrical wiring of a microphone system to plug into a radio bodypack?

    pcrecord Don't you want the best recording like I do ? Well-Known Member

    When I first saw the thread, I expected to answer saying you are better off with a sm57 or 58 at 100$ they spend time and energy on DYI kits.
    But when I read the question at 10$, I'm speechless. ;)

    You will need a capsule that are frequency compatible with the sources you use, some kind of isolated encloser to avoid vibration noises and stage spills. Matching all that to the body pack input specs. It's an interesting project. Let us know how it ends up !

    I admire your DIY attitude, but I personally believe you would be much better off searching the European eBay sites for a used Shure lapel / lavalier mic. The mini XLR connector that Shure uses (502-TA4F, available through Mouser) alone is going to eat up most (if not all) of your budget.

    There are a lot of factors involved even in taking a fully functioning lavalier mic from another manufacturer and making it work with your Shure transmitter. (pinout, operating voltage, impedance, etc.) Even when two manufacturers use the same connector, it's no guarantee the mic will work properly (or work at all) with both body packs.

    Then if you build one from scratch there's the issue of finding something to put the raw capsule in, that will not adversely affect the sound. Microphone companies do a lot of research and development to figure out the best way to vent, and the best way to seal, certain areas of the mic body to get the desired sound. Grooves, and slots, and mesh, and foam, and silicone, and rubber - each with an impact on the sound.

    Again, I'm not trying to discourage your DIY spirit, but there's more to this than meets the eye. So, unless you're very experienced and already very well-equipped I see this ending in frustration and money potentially wasted.

    Best of luck!

    thanks all for answers guys

    unfortunately i do not have the buget to buy brand microphones SHURE , AKG, Audio-Technica, Sennheiser ...

    the idea is that - i would like to made by me :) ... already i have a Lavalier cables , Mini-XLR 4 Pin FEMALE PLUGS and i have some experience in sound, soldering and electronics in general
    i need capsules parameters:
    good frequency response
    working voltage up to 2V
    omni or unidirectional
    impedance up to 2.2kohm
    possible parallel soldering of several capsules (2-6) for Accordion or Dulcimer

    i found a lot of information about Panasonic WM-61A, but these capsules are no longer produced
    now looking for something similar, something new... but tested by connoisseurs
    or something Dynamic Capsule or Speaker Transducer, but i'm not sure they can find Mouser.com

    PLEASE HELP ... i think this thread would be interested in more amateur

    P.S. sorry for my English

    ???? WTF? this alone demonstrates you don't have a clue what you are doing.
    look for used. there's a lot more to building mics that work correctly than just sticking an element onto a mounting device. .

    i empathize with financial challenges. when i was a kid i couldn't afford sh*t. you just have to focus on what you want. remember what you are trying to do is buy tools you need to do your profession. don't eat. walk to work, whatever it takes. invest in yourself.

    Surprisingly, this can be made to work, as long as sonic quality and low noise level are not on your list of requirements.

    You can buy electret elements from China for silly money - aliexpress, has tons of them.
    You can by ten for less than thirty dollars! Ideal for experiments.

    anyone tried this product: PUI Audio AUM-5247L-R ???

    You don't seem to understand. The Indian and Chinese market are full of these type of products, but you need to understand how it works. PUI Audio almost certainly don't make them, and you will find identical looking products everywhere. Some even use the same image. The reality is they are mass produced as unbranded items, and then smaller companies buy them and sell them on. They are the type of thing found in all sorts of products, some with BIG name makes. They are the main component of a vast range of budget end microphones and generally sound OK. What is not OK is that with expensive mic elements, the factories test them, grade them and even match them for stereo pair, so each mic sounds identical. These don't. They sound close, but the tolerances in manufacture are lower, being mass produced and there will be occasional failures. As I said, you can get these kinds of thing for very little money for lots, and if a few are not good, it doesn't matter for experimental purposes.

    No point asking opinion of them - for every happy person, another won't like the sound. They will probably have a 20-20K frequency response and pretty low noise figures. Frequency response will vary a bit, but be quite usable. Just remember the name means NOTHING - it's just the name the probable one man band decided to call his business. Just buy them and see. If you hate them, try something else - that's how it is.

    hello dear friends
    my problem was resolved
    i purchased from Mouser.com these PUI Audio AUM-5247L-R capsules, and works great ... good sound ... the days ahead, i will try to post a video comparison between AKG C519, Shure BETA 98H and my DIY stage mic PUI Audio AUM-5247L-R.
    Thank you all for your help, and thanks for this forum

    I'm very glad to hear you worked it out. I look forward to hearing the comparison results.
