| 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

The Shure 55SH Series II is a Unidyne cardioid dynamic microphone boasting a classic look and vocal-tailored sound for recording sessions, live stage applications, and on-camera use. The dynamic cartridge is shock-mounted to impede handling noise and vibrations transferred through your mic stand. The implementation of a cardioid polar pattern minimizes pickup of off-axis noise and ambience, yielding higher gain before feedback and attenuated stage bleed.
The mic delivers a frequency response of 50 Hz to 15 kHz with a gentle presence boost peaking at approximately 6.5 kHz. Its XLR 3-pin output ensures compatibility with most mixer inputs, microphone preamps, and portable PA systems. An on/off switch is provided for convenient muting of the mic between speeches or performances. The attached, self-tensioning, 5/8“-27 thread swivel mount can be tilted up to 45 degrees forward and 80 degrees backward. Chrome die-cast metal construction provides tour-worthy durability.
Classic Appearance
In addition to being a mic with solid audio characteristics for the studio and stage, the 55SH Series II makes a great prop microphone in video shoots, photos, and theater applications
Tailored Frequency Response
The 50 Hz to 15 kHz frequency response features a slight dip in the low-mid frequency range and a gentle rise from 1 to 10 kHz, making its sonic performance optimized for vocals, public address, and dialog
Cardioid Polar Pattern
The cardioid polar pattern is effective in minimizing sound pickup at the off-axis sections of the capsule, ensuring high gain before feedback
Shock-Mounted Cartridge
The dynamic capsule is shock-mounted for added protection against shock- and structure-born noise
