Shure SLX24/Beta87A System (SLX2/Beta87A Handheld Transmitter, Beta 87A Microphone & SLX4 Diversity Receiver)
Performance Gear Wireless Systems feature Shure's patented Audio Refrence Companding for crystal-clear sound beyond the limits of conventional wireless technology.
Shure Beta 87A Vocal Microphone
The Shure Model Beta 87A is a premium quality supercardioid hand-held electret condenser vocal microphone with exceptionally smooth frequency response and high sound pressure level (SPL) 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.
Leading the field for studio-quality sound in live performance, the Beta 87A has a smooth, tailored response for warm, accurate sound. Its supercardioid design provides maximum isolation from nearby vocalists or instruments. Supercardioid, Condenser.

Specification
Dimensions: 42 mm H x 197 mm W x 134 mm D (1.65 x 7.76 x 5.28 in.)
Weight : 816 g (1 lb. 13 oz.)
Housing : Galvanized steel
Audio Output Level: (ref. +/– 38 kHz deviation with 1 kHz tone)
- XLR connector (into 600 O load): –13 dBV
- 1/4 inch connector (into 3000 O load): –2 dBV
Output Impedance :
- XLR connector: 200 O
- 1/4 inch connector: 1kO
XLR output :
Impedance balanced
- Pin 1: Ground
- Pin 2: (+)
- Pin 3: (-)
Sensitivity : –105 dBm for 12 dB SINAD, typical
Image Rejection : >70 dB, typical
Power Requirements : 12–18 Vdc at 150 mA, supplied by external power supply
Operating Range Under Typical Conditions : 100m (300 ft.) Note: Actual range depends on RF signal absorption, reflection, and interference
Audio Frequency Response (+/– 2 dB): Minimum: 45 Hz, Maximum: 15 kHz, Note: Overall system frequency depends on microphone element.
Total Harmonic Distortion (ref. +/– 38 kHz deviation, 1 kHz tone): 0.5%, typical
Dynamic Range : >100 dB A-weighted
Operating Temperature Range : –18°C (0°F) to +50°C (+122°F), Note: battery characteristics may limit this range
Transmitter Audio Polarity : Positive pressure on microphone diaphragm (or positive voltage applied to tip of WA302 phone plug) produces positive voltage on pin 2 (with respect to pin 3 of low impedance output) and the tip of the high impedance 1/4-inch output.
