I was wondering what kind of microphone the dead were using in the 70's you know the time when they were using 2 I think one was being recorded and the other was for the live sound. Any idea's?

Thanks!

The Wall of Sound was designed to act as its own monitor system, and it was therefore assembled behind the band so the members could hear exactly what their audience was hearing. Because of this, a special microphone system had to be designed to prevent feedback. The Dead used matched pairs of condenser microphones spaced 60 mm apart and run out-of-phase. The vocalist sang into the top microphone, and the lower mic picked up whatever other sound was present in the stage environment. The signals were summed, the sound that was common to both mics (the sound from the Wall) was cancelled, and only the vocals were amplified.
