AKG CHM99W - CHM99 Hanging Condenser Microphone White

AKG CHM99W - Cardioid Hanging Condenser Microphone (White) for Fixed Installation

The AKG CHM99W is a white pendant condenser microphone designed for discreet ceiling pickup in choirs , houses of worship , lecture halls , theaters , and auditoriums. Its wide-aperture cardioid pickup pattern provides even coverage of sources below the microphone while maintaining good rejection of side and room noise. It offers a response of 70 Hz to 18 kHz , sensitivity of 18 mV/Pa (−35 dBV), and equivalent noise of 21 dB-A , achieving a natural sound with a signal-to-noise ratio of 73 dB-A . A special 10 m anti-kink cable helps maintain precise aiming and a spring-steel clip for hanging and angle adjustment. It connects directly to any balanced input via a 3-pin XLR and operates on 9–52 V phantom power (max. 3 mA). Its compact body ( Ø 13.5 mm × 55 mm ) and weight of 20 g make it a very discreet solution for permanent installations.
