ORIGINAL: Anaxagoras Yeah the Neumann is famous but wasn't familiar with the RCA. Many of those old valve ribbon mics are regarded as real classics though. Ribbon microphones are classed as dynamic microphones, i.e., no active electronics, valve or otherwise. As with any dynamic or non-active electronics mics, the output level is quite low. Condenser mics require active electronics as part of the circuit, which includes a wire soldered directly to to the diaphragm itself. Ribbon mics need the built-in transformer (an electronically passive device) to give any useful output at all. The RCA 44 ribbon microphone was used as the overall pick-up microphone, very often the only mic at all, in the majority of Hollywood movies till the early or even mid '50s. The sound we hear today from those efforts is more due to the amplifier electronics available at the time ('30s & '40s, remember, valves were very good at the time, but the necessary balancing transformers and output transformers not nearly as good as what we have today) in getting the low output of those mics into something we could hear at the movie theater. (Of course, the 106dB/w cabinets across the stage might have helped there, especially with the early Western Electric 300B 8 watt amps)> But the RCA 44 certainly has a 'speshul' sound, no question, and about the most accurate mic there is within the frequency range. Some guy makes perfect replicas of those mics today and gets anywhere from $3,000 to $4,000 per mic (depending on options), to this day. The mics, and the sound, are still highly valued, we can safely assume. Boy, if people only knew how many ribbon mics and valve ('tube,' 'röre') condenser mics were involved in the CDs they hear and the movies they see. Dinosaur technology, to make today's world listenable. PS I have actually held in my own hands the RCA 44 mic through which James Brown sang all his earliest hits. Al Green, after first giving up being a singer to become a preacher, searched far and wide to relocate his beloved RCA 77DX ribbon microphone when he decided to record again. The RCA 44 was used in front of Bill Wyman's bass cabinet on Brown Sugar ... who knows where those things might wind up being. But that's what we are hearing on those records, folks. Barbara Stanwyck, Cary Grant, James Brown, Bill Wyman's bass, all through the same microphone. Freaky, no?
