| Post subject: | Mic Question |
My main mics are Shure 87A'. Both wired and wriless. However, I bought a new one the other day more for the looks than anything else. Shure 55SH.. Often referred to as the "Elvis mic." Beside KJing at the club, I do private parties where I do most of the singing and with me doing more of the old stuff, I thought it would sorta go with the mood. I took it to the club the other night and it made a big hit. Many just had to try it out. has a great sound. The mic is of course styled like the old original, with a new SM58 inside. Ok, here's my question. I noticed that I had to turn the gain up about 25-30% more on this mic to get it to match the out put of my 87A wirless. I use a CFX12 mixer. Anyone with an idea why the significant difference in the settings? Would there also possibly be a gain setting on the mic itself? Maybe inside the switch? Thanks, Sorry. This should have been in the Technical Forum Kelly |

Most likely it's an impedance matching issue. The 87A is a condensor mic rated at aprox 100 ohms & the 55SH is a dynamic mic rated at 270 ohms which is most likely why you would need to turn it up more. With the 87 being a condensor is going to be more sensitive right off the bat as well thus not needing to turn up as high. We used to have one of those 'Elvis' mics as well, finally got rid of it, most people didn't know how to sing into it. They would grab it & sing into the top of it - even after some mic education, many still couldn't get the hang of it. But they are fun for nostalgia purposes & the new ones do sound good. |

Also, you have to think that just based on the shape of the mic, it simply can't pick up the same amount of sound as a cardioid mic can. Basically, instead of singing into a 3/4 sphere, you are singing into a semi-flat surface (probably with the cardiod inside, but still the same idea as far as input coverage). |

It could just be very directional with a narrow field. But everything has a different gain structure. Every machine I use, has a different point at which it will distort. So I have to adjust the channel gain up or down, for every one. |
