The Beta 87A has consistently been a top choice of performers and audio technicians around the world due to its superb accuracy and detail, and rich vocal production. This long-standing favorite now incorporates a cardioid polar pattern and has been named the Beta 87C TM.

Developed in response to professional demands associated with the use of personal monitoring devices like the Shure PSM ® Series, Shure's new Beta 87C premium vocal microphone delivers studio-grade performance and a smooth, extended high-end frequency response in a cardioid condenser design.

The uniform cardioid polar pattern of the Beta 87C enables users to effectively reject ambient noise arriving at the rear of the microphone, an attribute that will be especially appealing to users of personal monitors and others who frequently experience undesirable sounds bleeding into their mixes.

Other features include:

Smooth, wide frequency response with slight presence rise
Uniform cardioid polar pattern for maximum isolation
Minimal off-axis tone coloration
Low-frequency roll-off compensates for proximity effect
Three-stage pop filter minimizes breath pop and noise
Break-resistant stand adapter
Frequency response: 50 to 20,000 Hz

SLXTM Wireless Systems feature a wide variety of industry-standard handheld vocal microphones. Options include the Beta 87A or C, Beta 58A®, SM86, and the legendary SM58®.
