Product Description
-------------------
Excellent for touring professionals, the BETA 87C premium vocal
microphone delivers studio-grade performance and a smooth,
extended high-end frequency response in a cardioid condenser
design. The microphone adds warmth to the frequency response and
creates an ideal environment for personal monitoring. And its
highly consistent cardioid pattern offers excellent rear
rejection. Vocalists who use personal monitor systems such as
Shure PSM will appreciate how effectively the BETA 87C rejects
ambient sound from the rear of the microphone.

From the Manufacturer
---------------------
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
