CM-10/E, Crown Omnidirectional Condenser Lavalier Microphone (New Old Stock) The Crown CM-10/E is a professional quality, omnidirectional electret condenser microphone designed for lavalier use in professional broadcasting and sound-reinforcement applications. The CM-10/E is supplied without a connector, for connection to a wireless mic transmitter of your choice. Cable length is 4ft.Although it is economically priced, the CM-10/E features a very smooth, wide-range frequency response for natural reproduction of the voice. The response rises at hig frequencies to compensate for the mic being off-axis to the mouth, and rolls off below the voice range to reduce pickup of low-frequency noises.A rugged tie mount clips securely to the tie or shirt, and the capsule can be inserted for use on the left or right side. The cable exits from the side of the capsule and can be easily hidden.
