Shure BETA 87A Vocal Microphone

The Shure Beta 87A is a premium quality supercardioid hand-held electret condenser vocal microphone with exceptionally smooth frequency response and high sound pressure level capability. Used for professional sound reinforcement, broadcasting, and studio recording applications, the Beta 87A combines superb performance with the ruggedness needed for touring and field production.

The Beta 87A features a controlled low-frequency roll-off that compensates for proximity effect and prevents the “boomy” sound often associated with close pick-up. The characteristic Shure presence rise brightens the upper midrange. The tight supercardioid pattern, with null points at approximately 125 degrees, provides maximum isolation from other vocalists or instruments while offering minimal off-axis coloration. The Beta 87A operates on phantom power.

Microphone Specifications

Microphone Type
This is the type of microphone included with the purchase of the item.

Wireless:All of these microphones can be used without the necessity of wires or cables to connect them. They usually come with a receiver that connects to the input device where the audio signal is being sent.

Shotgun: These microphones are suspended on a boom and are used primarily in video production and broadcasting.

Lavaliere: These microphones are clipped on to the lapel or tie of the talent for broadcast and video production audio.

Table Top: These microphones are designed with a built in stand or to be placed on a table top stand to be used for broadcasting and podcasting applications.

Headset: These microphones are to be worn on the head typically for live performance and theater production.

Handheld: These microphones are held in the hand and are used in a wide range of applications primarily vocals and public address.

Clamp On: These microphones attach directly on to an instrument.

Drum Package: These microphones are an all in one package for drums typically made of dynamic Kick, Snare, Tom, and a stereo condenser pair of overhead mics for Cymbals.

Polar Patterns
The polar pattern of a microphone determines how sensitive it is to receiving sounds as they arrive at different angles.
Super-Cardioid
Transducer Type
The transducer type is the manner in which the audio signal is converted into an electrical signal.
Condenser
Address
The configuration of the capsule determining on which side the microphone is sung or spoken into.
Top
Frequency Response
The range of frequencies the speaker will reproduce (lowest frequency to the highest). Bigger is better, meaning the wider the range, the better. The optimal range is 20 - 20,000 Hz (which is the range of human hearing).
50 - 20,000 Hz
Sensitivity
An efficiency or sensitivity rating tells you how effectively a speaker converts power into sound. The higher the number, the more efficient the speaker and the louder it will play with the same input power. An efficient speaker helps you maximize your available power. Most sensitivity ratings measure the speaker's output with 1 watt of input, 1 meter from the speaker. Some speakers' sensitivity is measured with 2.83 volts of input, instead of 1 watt.
 
Efficiency (1w/1m) is not an accurate indicator of a subwoofer's output capability and should not be used as a comparison to other speakers or subwoofers to determine which one is "louder".
94 dB
Signal-to-Noise Ratio
This spec compares the strength of the signal to the level of background noise. A higher value indicates less background noise.
70.5 dB
Maximum Sound Pressure Level
This is the maximum sound pressure level that the microphone is capable of accepting and transferring into an electrical signal.
140.5 dB
Output Impedance
This is the amount of impedance that the microphone allows.
150 ohms
Power Requirement
Condenser microphones require an external power source to operate. Typically a +48v DC charge commonly refereed to as Phantom Power.
+48v (Phantom)
Connection Type
This is the manner in which the microphone connects to the source unit. For wired microphones, this is the connector that directly connects the microphone to the mixer (or other input source unit). For wireless microphones, this is the connection that connects the microphones receiver to the mixer (or other input source unit).
