This is an audio kit consisting of an omnidirectional electret microphone and a separate interface adapter. The microphone has a specified range of 25 feet and features an adjustable gain, a low-noise pre-amplifier, and a treble boost circuit. It is designed for flush or surface mounting on a standard electrical box. The interface adapter provides a standard RCA jack output for connecting to recording equipment and includes an LED power indicator and reverse polarity protection. Both the microphone (SM1) and the interface adapter (SM2) require a 12V DC power supply, each drawing 10mA. Operating temperature, ingress protection, and specific environmental ratings are not provided in the specifications.
