I report news, and having a background in radio, I am full aware of the RE-20's reputation as a studio and broadcast mic. I have spent numerous hours behind many an RE-20, and I have to say that, of the standard broadcast quality microphones I have used, the RE-20 is the one I like the best.
But now, I may just have a new favorite broadcast mic with the RE-320. I have to admit, though, it was hard putting the RE-20 in the road case and placing it in the cabinet for a vacation, kind of like saying good bye to an old friend. I have not had the chance to test the RE-27, but I do have the opprotunity to put this RE-320 through the paces. In just the short time I have been using this mic, I have to say the sound is very similar to, yet distinctly different than, the RE-20. With crisper highs and a tad less mid, I find the RE-320 fits well with my voice and style of delivery as a news broadcaster. The sound is warm and smooth without the harsh crispness of a similarly priced, over driven large diaphragm condenser offering. Not being a fan of LDC mics because of the lack of off axis rejection, I have to say that in a world where more and more studios and professionals are going with LDCs, this RE-320 should not be overlooked for a not-so-ideal studio environment. Because of it's heritage and price point, I think this is an excellent addition to any mic closet or broadcast booth.
The selector switch where the bass roll off would be on the RE 20 or RE 27 is present, but it holds a different function, and there is a notable difference in the sound, as was intended. You wont get the two mixed up when speaking into this mic if you are listening through a set of cans. The instrument setting is definately flatter and not real suitable for vocals.
As usual, the RE-320 has the internal pop filter, which works fairly well. I have seen (and purchased) the metal mesh pop screen from a reputable broadcast equipment outfitter that is designed and painted to match the RE-20, and I have to say, I like working without the screen better, as I can get a bit closer when needed for effect.
Internally, the RE-320, as per the company's website, is similar to the others in that it utilizes the same humbucking coil technology found in the RE20 and RE27 to arrest electro magnetic field interference. This offering from EV is said to be similar to the RE-27 with it's Neodymium Magnet that increases the output slightly, which is nice as I can now back off the trim a bit to remove any hiss that might be present in the signal while recording. The classic look and feel of this mic is similar to the RE-20, and that makes it comfortable to be in front of, just like an old friend. The interior shock absorbtion is what can be expected from any of the RE series broadcast mics, making the external shockmount not neccessary, but desired in a broadcast setting where the broadcaster has to move around and take the mic with him (or her).
