The AKG Model D 310 cardioid dynamic microphone


Description and Applications Not much has come to light on this one so far. Similar to D 320 B, but with cardioid polar pattern. Slimmer than the D 330 and D 320, but service requires use of a soldering iron. There are no frequency response switches. Recommended for such applications where manipulation by the performer is not desired. D 310 S is identical to D 310, but with on/off switch, lockable in its “on” position.
