| Headworn Condenser Microphone. Made by Crown. (EM.CRW-CM-311AE)
PLEASE NOTE THESE MICS DO NOT HAVE A PRE-SET CONNECTOR, PLEASE CALL AND SPECIFY WHAT UNIT CONNECTOR IS NEEDED!!! Used by world-renowned artists such as Garth Brooks, Britney Spears and Janet Jackson, the Crown CM-311A Differoid microphone is the headworn microphone of choice for the live-performance industry. Featuring clear, crisp vocal performance in a lightweight package, this microphone signifies the quality and performance value of the Crown CM Series of microphones. Developed for and with major performing musicians reaching for clarity with increased gain before feedback. Crown’s differoid concept was perfect for the task. The CM311A increases gain before feedback by as much as 6-12dB. The Crown CM311A only transmits what is the differential of the front and back elements increasing rejection of unwanted background noise and discriminates against distant sound sources such as monitor loudspeakers and instruments. Solve your on-stage problems with a hands free CM311A. The CM311A terminates in a belt clip housing that can be phantom powered or battery powered. It has XLR out as well as a line out to feed a wireless transmitter. The CM311AE is provided with stripped leads and a wiring diagram for popular wireless systems.
