Members djiceman1575 Posted August 18, 2012 Members Share Posted August 18, 2012 We were using a Beta 58A on the gig I ran sound for tonight (first time ever, lol), and I was taught when using the SM58's to position monitors off-axis to prevent feedback. Is the Beta 58A the same way? I know it's super cardioid IIRC, but tonight when we used it (mind you, this was on the patio of a restaurant, and the band was in the corner literally) we had a bad issue with a mid-band hum (somewhere in the 400-600 cycles range), no amount of EQ helped. The mic was approx. 5ft off the ground, slightly off center from the monitor, and horizontally positioned. I'll try to dig up a picture to explain what I mean... One thing I did learn, those mics capture a LOT of bleed! Link to comment Share on other sites More sharing options...
Members Rezrover Posted August 18, 2012 Members Share Posted August 18, 2012 New place, new mic, gotta ring out your monitors. Great mic, probably picking up feedback you didn't know you had. How do you set your gain for the mic? What was the mic used before? Link to comment Share on other sites More sharing options...
Members Coaster Posted August 18, 2012 Members Share Posted August 18, 2012 no eq helped, 400-600 cycles, outdoor patio = modal ring. been there, done that, pinked it and smaart'ed it. compromise is the solution, you cant win a modal ring without non sound equipment.

Members BlueGreene Posted August 18, 2012 Members Share Posted August 18, 2012 That's a great mic! No amount of EQ helped? As in you tried to notch it out and didn't work? At the +/- 15 db setting???? Link to comment Share on other sites More sharing options...
Members agedhorse Posted August 18, 2012 Members Share Posted August 18, 2012 Could be caused by a combination of things that were present here. Now it's certainly possible that the mic is a counterfit (I haven't had any significant problems with real B-58's) it would pay to double-check everything including channel that may have been set to inadvertantly contribute to the problem.

Members djiceman1575 Posted August 19, 2012 Author Members Share Posted August 19, 2012 I don't think it was a counterfeit...I'll have the guy I loaned it off of let me look at it. I do need to get a nice RTA soon, and it's definitely in the plans (as always). Link to comment Share on other sites More sharing options...

Unless it was bought new from an authorized Shure dealer (an honest one at that), it's just as likely to be a fake. An RTA is likely to be as much a hinderance as a help as well, unless you bother to learn how it works and what it will not tell you accurately. It can lead you down an incorrect path pretty easily.
