DESCRIPTION The TOA EM-600 has an unobtrusive design that allows simple flushmounting in walls, ceilings and desktops, making it particularly well-suited for conference room recording, as well as in security monitoring applications. An electret condenser microphone element’s omnidirectional pickup pattern ensures a high degree of sensitivity and a wide frequency range. The EM-600’s has been designed to minimize interference from low-frequency sounds that may degrade audio reproduction. It also incorporates two rubber isolation rings to resist vibrations that may adversely affect audio quality.
