Hypercardioid, studio-quality boundary microphone with rugged, "non-crush" case and switchable bass-cut filter for reducing footfall noise, ideal for tough on-stage assignments. Other benefits include optimum acoustic properties, high directivity, and neutral sound. Having the same frequency response, the C 547 BL can be combined with the CK 47 with excellent results.

Primarily designed for use in places of worship, theaters, and conferencing, the C 547 BL is also a good choice for miking kick drums and other instruments.
