Demanding audio environments require flexibility, reliability and clean and intelligible audio. The CU-F117 capsule is developed from the F-780 capsule. The CU-F117 used in combination with the WRT-847B handheld transmitter offers omni-directional pick-up characteristics while maintaining a strong sound. While the well-balanced audio characteristics allow for a range of use it is ultimately suitable for speech where environmental noise is limited such as various in ENG applications.
