Mikrofon SHURE Beta87A

Mikrofon SHURE Beta87

Cartridge Type

Condenser (electret bias)

Frequency Response

50 to 20,000 Hz

Polar Pattern

Supercardioid

Output Impedance

Rated at 150 ohms (100 ohms actual +/- 20%)

Recommended minimum load impedance: 800 ohms

Sensitivity (at 1,000 Hz)

Open Circuit Voltage -52.5 dBV/Pa (2 mV)

(1 Pa = 94 dB SPL)

Clipping Level (at 1,000 Hz)

1000 ohm Load: -6 dBV (0.5 V)

Maximum SPL (at 1,000 Hz)

140.5 dB (0.25% THD, 1000 ohm load)

Self-Noise

(equivalent sound pressure level; measured with true rms voltmeter)

23.5 dB typical, A-weighted

25.5 dB typical, weighted per DIN 45 405

Dynamic Range

117 dB (maximum SPL to A-weighted noise level)
