All in ONE Microphone

After years of research in the laboratories
of Microphone Headquarters, the dis
covery of a practical method of obtaining
velocity or pressure-gradient operation
in a crystal microphone now makes pos-
sible Controlled-Direction responsev-a
feature never before available in any mi-
crophone! By electrically combining the output of the velocity"
element with a pressure" element, and by using the elements separately.
the following directional characteristics are instantly available through
a 3-point selector switch.

1. Uni-Directional. (velocity" plus "pressure") Wide-angle front-side
pickup-dead at rear. Cuts out audience noise, reduces reverberation
energy pickup 66% . eliminates feedback. The first economical micro-
