C 547 BL 

"Non-crush" case
Inconspicuous
Hypercardioid polar pattern
Easy to repaint
 
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.
