Michael Render Posted May 22 Report Share Posted May 22 This weekend, I was at a gear swap when I stumbled across this shotgun mic from the 1960s. The ElectroVoice 644 CardioLine. The only thing I know about them is that they are a dynamic shotgun! Does anybody know anything about these? Quote Link to comment Share on other sites More sharing options...

PMC Posted May 22 Report Share Posted May 22 Oh my gosh. We had one of these at the NBC station I shot news at in the late 70's. We plugged it into our Frezzolini 16mm, mag sound cameras (with augenieux crank zoom lens). Back then I had no idea what an interference tube was but I think this has one. As I remember it had a 2-pin screw-on connector to XLR cable. It worked better than our other microphones (EV635) at picking up distant sounds but I was a snot-nosed kid back then, fresh out of college. What did I know. I can't remember the level of self or handling noise. Thanks for the trip through memory lane. And it was HEAVY. Quote Link to comment Share on other sites More sharing options...
Philip Perkins Posted May 22 Report Share Posted May 22 Very common in TV news conferences etc back in the day, and used as a boom mic on Fisher and Mole "perambulator" booms for TV shot on stages for many years. Quote Link to comment Share on other sites More sharing options...
DHB Posted June 25 Report Share Posted June 25 Oh, I'm a bit late to the party, sorry ..yes, I have one of these, and also the version with the rubber-ring 'handling-deadener', I mean isolation mount: the 642. Surprisingly clear, effective, but no bass. Supposedly 40Hz-12kHz (..though some specs say 30-10kHz ..but I can't quite believe THAT). As they're unpowered dynamics (ultra-cardioid) they have no 'self-noise' from internal transistors, tubes or suchlike, so you get absolute silence if no-one's speaking, or nothing nearby is making any noise. Simple, clear, a bit 'tinny' (must be the Acoustalloy® diaphragm). Low frequency roll-off switch and variable impedance settings. Very useful, but rather dated. I rather prefer an AKG 480 with a shotgun capsule. But the 644 can withstand any amount of dropping on hard surfaces! Oh, I forgot to mention Martin Mitchell's comprehensive page(s) about this mic: tinyurl.com/C4rd1l1ne Quote Link to comment Share on other sites More sharing options...
Jim Rillie Posted June 26 Report Share Posted June 26 Oh yeah. The 642 had a huge heavy magnet.Hand held was the way I used it back in mid seventies.. Quote Link to comment Share on other sites More sharing options...
