You say you're working the sm7 from about 6 inches.... Get closer. If you were to pull off that big foam cup of a windscreen, you'd find that the diaphragm is actually much further back in the body than you might think. Secondly, you'll get the benefit of the proximity effect, which will fill out your sound a bit, and reduce your need for additional gain just a tad.


Great point. I think I measured once the diaphragm to the end of the "cage" and it's about 4inches. Im using the smaller foam windscreen. So actually as we speak I'm 10" from the diaphragm. If I closed the gap 4" I would still be 6" from the diaphragm. Cool

Sounds like you may have started from a set of processing presets you used previously with other mics. Begin again from scratch (after noting those presets, so you can recreate them if you need them


I think what's causing the headache is the 5db bump@ 1780khz. Most all of my other mics benefited from this in the form of some presence. I would be more than happy to simply dip @ 200-500hz somewhere and Hi pass @ 80hz,, IF I could get some clean gain. Mayb I should play a bit more with the presence switch on the Shure itself

Don't sell it yet. The sm7 is a workhorse, and, for most of us, a keeper. It is a different animal from the condensers you're used to, and might take a little while to adjust to.

Hope I've been helpful. Inoccent


Of course.. Thanks all for the encouragement and advice.

Hi Capt. Did you say you were running a preamp thru the MBox Mini and you are by-passing the pre's inside the MBox? I'm not understanding having the gain on your MBox cranked up if you are already using a preamp or did I get that wrong? Just curious.

The FetHead is similar to a Cloudlifter. Without it, there's not enough gain.

+1 for Don

Get closer. I use mine without any foam but with a metal screen pop and on occasion I will throw a chunk of panty hose over the mic. Not the screen. My pop screen is only an inch or so away.

The caveat... your going to get more proximity effect so you may have to adjust your hi pass and eq.

These old ears tell me your hiss is is hardware related. Gain is my guess. Get closer, turn down your gain, reduce your recording level then bring it back up in post.

Bob

Closer to the mic, 2" or so distance from foam.. PreAmp gain reduced to 12:00... I can hear a difference... noise floor? I came up with -58db or so.. an improvement though overall
