Phantom Power Bleed

[T.O.I.Y.Z.]

Here is a question I have I hope someone can answer....I have read that certain mixers and pre-amps don't supply enough power to multiple mics running through them. I have a Yamaha MG10/2 mixer, a Samson CL-7 and a Shure SM58......Follow this.....

I have both mics plugged into their own individual channel on my Behringer Mic2200, then from the MiC2200 they go to a Samson S-Com Compressor, and from the Compressor to the Yamaha MG10/2 mixer, to the Behringer UCA202 interface, to the computer.....

The Samson mic works, but I can't get any volume out of the Shure mic.....I read up and saw that the Samson mic can work on varying voltage levels within the Phantom Power, obviously the Shure mic can't.....Are there any other Large Condensor mics that can do this?....I want to have two diff mics in use, so that I can have a choice for the diff vocalists that come through to record, instead of being stuck with only ONE mic for everyone...Is there a mic that you guys have that has flexable voltage amounts but uses Phantom Power?

The 58 is a dynamic mic and doesn't use phantom power. Having the phantom power on won't hurt anything, it just doen't do anything.

A 58 needs a lot more gain from a preamp than a condenser (like the sampson) does. That's why you are having this problem.


BTW, you don't need to triple post. You will get the same answer, and it tends to piss people off. Pissed of people aren't very helpful.

SM58Mic

So are you saying, that is normal and I just need to crank the volume up on the SM58?

The 58 needs somewhere around 50db of gain, a condenser mic needs much less. Dynamics are much less sensitive, that's why they don't feed back as much in a live situation.

Surely the MIC2200 can supply 50dB of gain for the '58?

The mic2200 maxes out at 60db of gain.

Remember that the output is also related to the input. If the sound you are trying to record is quieter than the laboratory test sound, you will need more gain to get the level.

You should also keep in mind that you are trying to get the level up to line level, which will be around -18dbfs in your computer. If you are trying to get a steady tone to sit around 0dbfs in the computer, you will need another 18db of gain on top of the 50db.
