CAD Astatic Omnidirectional Button Microphone ~ White

Regular price £319.99

Tax included.

Miniature-boundary microphone designed for installation in security, ambient monitoring and observation applications. Astatic’s internal audio limiter circuitry tames high sound pressure levels and improves intelligibility by protecting the audio signal from distorting sensitive recording circuitry. The integrated 180Hz, 6dB/oct high-pass filter attenuates unwanted low frequency energy. 9 to 24 VDC (70mA) is required to power the microphone (not supplied). The connector accepts DC power and outputs an unbalanced, amplified signal. The threaded housing makes for easy installation into ceilings, walls, tables and other surfaces. Rubber isolation bushings and metal nut/washer hardware are also provided.Specifications:Operating Principal Permanently-Biased CondenserPolar Pattern OmnidirectionalFrequency Response 120Hz – 18KHzSensitivity -30dBV (32mV) to +8dBV (2.5V)@ 1 PaImpedance 50 ohmsMax SPL 110dBSelf Noise 22dBAPower Requirements 9 to 24 VDC, 70mA
