Hi, I have a problem. The lady singer that I play with has her own mike (SM58 Beta)& no matter what I do it feeds, booms &is very microphonic. My first thought was that it was a fake but she bought it from a reputable shop.it produces a lot of handling noise.She tends to eat the mike so it tends to be a bit heavy on the bass(proximity effect)I use an AKG & have no problem whatever & find it has a higher output lower handling noise& much more definition. I know it sounsd strang but I am wondering if her mike just dosent like my pa.(Dynacord desk ,pair of SR tops and a 300watt SR powered Bass Bin) Any suggestions much appreciated as this is driving me batty.

Hi Chris,
There is no way that an SM58 would not be compatible with your PA.
Shure SM58s and 57s are industry standards. Millions of musicians use them in all kinds of situations. These mics are easy to work with and get a great sound. I have rarely seen one that didn't deliver. Even dented old rock venue SM58s that have been dropped and spat on for a few years work fine.
There could be a fault with the mic. Test it through something else, a guitar amp, anything.
It sounds to me like it has been damaged. You have to test it through something else. If it still does it, send it back to Shure for a repair, or get another.
It could be a fake Shure SM58 - there are lots out there. But if it came from a good shop it is unlikely.
I reckon it is damaged.
Let me know how you get on
Shine On
Michael

Hi, the strange thing is that she sings with a function band as well and has no problem.There is nothing wrong with my desk& I don't have the problem with any other Mic.Playing mostley small venues I thought that the speakers were to close to the Mic,but last night we were in a large hall with plenty of room to set up & still had the problem.

You've got me there. I don't know what it could be.
Although your singer says she has used it with other PAs, I would still recommend testing it yourself through another amp.
If it is too microphonic and picking up handling noise, it has to be the mic and not the amp.....I think?
One thought, although I am sure you have checked this....but could it be the lead?
When you do find out what it is, let me know.
Shine On

Guessing, I'd try to exclude the lead from the equation before anything else as well. A high capacitance lead would dump a lot of the treble to ground and you'd wind the wick up to compensate. Although not a recommendation (and no connection etc) I only use Cleartone leads from Award-Session. (Other cables are available etc...!) Cleartone leads also use low noise (as in dragging across the floor)cable. There is excellent cable (and other) information on the A-S website.

Cleartone leads also use low noise (as in dragging across the floor)cable. There is excellent cable (and other) information on the A-S website. Cable capacitance in this case is very unlikely to be the problem. The Shure SM58A beta is a purpose made vocal mic with quite an aggressive bass roll off and a built in shock mount to minimise handling noise. It is a low impedance mic designed to be used with balanced mic cable into a relatively low impedance balanced input mic pre-amp. Low impedance mics running into a low impedance input do not suffer from treble loss due to cable capacitance like high impedance guitar systems. The low impedance system is designed to minimise cable loss, cable noise and hum pick up. It does sound like either the mic, the cable or the mixer input you use are faulty. Does your mixer have low impedance balanced inputs, are you using a good quality balanced mic cable, is the channel switched to the right gain setting. If you have to really crank the gain knobs on the channel with that mic that's a clear indication something is wrong. If you plug your mic into the same channel using the same cable does it work OK. |

I'm no sound man, but I do have to run a house PA every week, with varying degrees of success. I had something pointed out to me the other week by a soundman who happened to be in the club when I was struggling with the onset of feedback. The desk has semi-parametric pots for the mid-range and I really didn't understand what I was doing with them!
Does your desk have a graphic EQ? Does it have parametric or semi parametric EQ? Particularly if it has parametric or semi-parametric, it will need a certain amount of understanding on how to use it correctly to get the best out of it. It was my lack of understanding that had been causing feedback on several occasions.
I may be barking up the wrong tree here, but thought I'd let you know what problems I'd experienced - with this type of control, you really need to understand what frequencies you are selecting and how much you are cutting or boosting them - my trial and error technique was pretty ham-fisted!

Hi again, Its not that the mike is feeding but that it seems to have a low out put and a muddy sound &a huge amount of handling noise..I have used different inputs & it still sounds crap ( just touch the mic stand and you get a echoing thud that wont go away) I have never seen her band play & if they get this sort of sound all the time I dont think I want to. Thanks for your help. Chris

Some while ago I had a similar problem. The fault was cured when I bought the best cables I could find.
At my last gig I had the SM58 plugged into the Bose and a SM57 next to it plugged into the mixer (for a guest guitarist to play through) and then into the guitar input in the Bose.
There was no problem with this at all, and I think the answer lies with the cables.
This may not, but I hope it does help.
