This black Shure MX393/O Microflex is a omnidirectional boundary microphone designed to capture high-quality speech and voice for sound-reinforcement and teleconferencing installations in governmental, institutional, religious, and business settings.
The MX393/O can be permanently installed on conference tables, desks, or lecterns. Its sleek, low-profile design is ideal for conference rooms and other sites where minimal mic visibility is of high priority and aesthetics are important.
The microphone features a omnidirectional polar pattern best used for several people sitting in a circle around a table. The mic takes advantage of the boundary effect to capture clear speech with reduced room ambience for intelligibility. The interchangeable capsule design provides the installer with greater flexibility and makes it possible to easily reconfigure microphone coverage as the need arises.
The MX393/O is equipped with a programmable, silent membrane switch with a bicolor LED that indicates the status of the mic.
The mic resists interference from devices such as cell phones and two-way communication devices. It requires 11 to 52V phantom power to operate. Included is an easy-to-use paint mask for custom-color installations.
