IntroductionMicrophones are an indispensable part of sound production in modern music, film and audio. Also known as mic’s, these audio devices convert sound waves to electrical energy. There are many types of microphones available in today’s market, with varying levels of sensitivity, frequency response, and directional abilities. One of the most popular microphones available today is the Shure SM Series utilizing the patented SM-PEG-PPC variable-density plastic housing. The SPM0687LR5H-1 is a specialized microphone within this series.SPM0687LR5H-1 Application FieldThe SPM0687LR5H-1 is designed for live sound reinforcement for vocal and instrument microphones. Its precision craftsmanship and cutting-edge technologies are ideal for use in recording studios and on-stage. This microphone includes a low-profile mic clip with a 5/8-inch thread for mounting onto a standard mic stand.The SPM0687LR5H-1 is well suited for use as a vocal mic in recording and live performance situations. Due to its rugged construction and high-end sound quality, it is suitable for harsh environments such as touring and production spaces. The microphone is also suitable for use as an instrument microphone, providing detailed clarity and response that allows a musician to focus on their playing without suffering from feedback or other unwanted sounds.SPM0687LR5H-1 Working PrincipleThe SPM0687LR5H-1 utilizes the classic dynamic microphone technology to convert sound waves to electrical signals. A diaphragm mounted inside the mic\'s housing vibrates when it detects sound waves, in turn moving a permanent magnet and induction coil assembly. This assembly creates a variation in the audio signal from the microphone.The SPM0687LR5H-1 operates on the super-cardioid pick-up pattern, which is a subset of the standard cardioid pattern. This pick-up range focuses on sound from one direction and helps to reduce feedback and other unwanted sound.In addition to its cardioid design, the SPM0687LR5H-1 features low-frequency resonator and high-frequency boost to provide a warmer, yet detailed response. This produces a full and balanced sound with low-end momentum and crisp high-end detail.ConclusionThe SPM0687LR5H-1 is a versatile microphone from the Shure SM Series. Its rugged construction and user-friendly design make it a great choice for a wide range of applications, from live sound reinforcement and vocal recording to instrument microphones. Additionally, its low-profile mic clip makes it easy to mount directly onto a mic stand and its patented super-cardioid technology provides enhanced sound pick-up and feedback reduction. With these features, the SPM0687LR5H-1 is an excellent choice for any sound production.
