The velocity microphone, also known as the вЂњpressure gradientвЂќ type, responds to the difference in instantaneous sound pressure on the front and back of the moving element. Also, the paint finish is wrinkle-textured, unlike the later mics.вЂќДЄ close-up of a V-2A with its ribbon element having been replaced by a moving coil. Sank continues: вЂњThe shape of the lower body casing and label plate is the easy way to recognize one of these V-2s (as seen above), versus the straighter lines of the V-2A/V-1/V-3 housings. The early V-2 model was a superior-sounding mic to the V-2A/V-1/V-3, but with quite lower output level caused by the much lower magnet mass and flux density, and the spring suspension was surprisingly effective at shock and handling-noise isolation.вЂќ вЂњThe V-2A, rather than designating the aforementioned moving-coil conversion and downgrade, merely indicates the later, more commonly seen version of the E-V ribbon motor, as seen also in the V-1/V-3, with a single cylindrical magnet held behind a pair of flat-plate iron pole pieces, with welded tabs holding the magnet, and the huge 0.2525-inch-wide ribbon. вЂњIncidentally, hereвЂ™s another piece of factual info about the V-2: The first V-2s were very different mics inside than most E-V V-series ribbon mics, in that they had a narrower ribbon (0.17 inch wide, same as the RCA Type 74-B), and a very different motor structure, comprised of a pair of horseshoe magnets screwed to each end of a pair of crude, straight-bar pole pieces, with the whole assembly spring-suspended from the interior frame.вЂќ See next image. Despite how cheaply the E-V ribbon mics were made, when properly ribboned, they can sound quite gorgeous (when low-Z or made to be low-Z), which was quite a surprise the first time I did one. вЂњBasically, IвЂ™d just like to reduce the number of times mic buyers get screwed in buying V-2/3 mics.

Incidentally, the V series E-V mics have the widest ribbons I have yet seen, at 0.2525 inch, which is quite a bit wider than the next widest, the RCA 44 series, which are 0.19 inch. вЂњFortunately, the V-1 ribbon motorвЂ™s pole pieces were part of the main casting of the mic, so they can be relied upon to still be ribbon mics, although virtually always high impedance.

Sadly, since the entire motor structure is removed when these are turned into poor-quality moving coil mics, there is no way to reverse the process other than to install a motor from another mic. вЂњSo, anytime a V-2 or a V-3 comes up for sale anywhere, itвЂ™s completely hit or miss to know if you are buying a ribbon velocity mic or not, unless the seller provides a look inside. No matter how good the moving coil dynamic element is (and to my ears they are bloody awful), itвЂ™s still turning a ribbon velocity mic into a moving coil pressure mic, and, in my opinion, completely ruins the sound and value of these mics. Not many were made and they are quite scarce.вЂќ Stephen Sank adds these observations: вЂњThis, if it was done by E-V, and I have seen enough V-2 and V-3 mics butchered in this way that I think E-V was actually responsible, was a dishonest and terrible thing to do to вЂњrepairвЂќ these mics. At least as good as the ribbon version with much higher output. If you are lucky enough to find one that is working properly, it is a really great-sounding mic. But if you remove the cover the difference is obvious. They are identical to the earlier versions including the label and velocity designation. There is no way of knowing this from the outside of the mic. These elements can be found only on the very last runs of those two models. They replaced the ribbon element in the V-2A and V3 with an Acoustalloy Diaphragm. Dennis Schrank explains: вЂњIn the mid nineteen sixties Electro-Voice sudВdenly and quietly discontinued manufacturing ribbon mics.
