Voice Communication Microphones
The Shure Specialty to General Communications Microphone Series
5-22 is a dynamic base-station microphone for radio
communications, paging, and dispatching systems. Its cardioid
(unidirectional) pickup pattern suppresses unwanted background noise
from nearby dispatchers, ventilating equipment, or office machines. It also
can reduce feedback in public address paging applications.
The 52-2 can be converted to Monitor/Transmit switching with the Shure RK199S SplitBar Conversion Kit.
