| Wow, that sounds pretty unusual for that mic. Maybe we can figure out what's going on.
Let's find out if the ribbon tension is close to correct - set up the mic to make a recording, then gently say "puh...puh...puh" in front of it - close enough to excite the ribbon. Make a recording of this. Then analyze the fundamental frequency of the ribbon oscillation using whatever software you have handy that can do this.
Another way to excite the ribbon is to repeatedly tap the body of the mic with your finger - the ribbon will oscillate at its resonant frequency. That mic should have a resonant frequency around 40Hz. If you don't have analysis software post a short clip or send it to me and I'll analyze it. If the ribbon is way too tight it will create a series of resonances from the upper bass into the lower midrange.
Also do a visual inspection to make sure the ribbon is not dragging on one of the magnets. Hold the mic up to a strong light or window - you should see light between the edges of the ribbon and the magnets. |
