CMC Electret Condenser Microphones

Same Sky CMC Electret Condenser Microphones are 1.5 to 4.5V_DC microphones that convert sound into an electric signal. The condenser microphones are unique and feature a high acoustic overload point (AOP, also known as maximum input SPL) of 130dB. Same Sky CMC microphones contain a permanent charge so that they do not need an external polarizing voltage. These CMC omnidirectional, unidirectional, or noise-canceling microphones offer diameters as compact as 3mm in a variety of configurations and sensitivity ranges from -24dBA to -54dBA.
