| Supercardioid Condenser Boundary Mic. Made by Shure. (MP.MX392-S)
MX392/S There's never been smarter boundary microphones than the Microflex models from Shure. With many models to choose from, equipped with features like programmable, silent membrane switches, logic inputs and outputs, and LED indicators, Microflex Boundary microphones are the high-quality solution for a range of applications, such as altars, boardrooms and distance learning centers. Every Microflex Boundary microphone features one of the new interchangeable condenser cartridges. Available in Cardioid Supercardioid and Omnidirectional polar patterns, the Microflex cartridges give you superior Shure quality sound options for every installation. In addition, their programmable switches offer the flexibility to be set for Push to Talk, Push to Mute or Push On/Push Off modes. Attractively designed with a low profile, professional appearance, the Microflex Boundary microphones come with an easy to use paint mask for your custom-color installations. The MX392/S is a surface-mount microphone designed for permanent installation in boardrooms, alters, and conference room tables. It includes a programmable membrane on/off switch, LED logic input/switch logic output terminals, an on/off indicator LED, screw terminal connections, and 12' attached unterminated cable. Features: - Flat frequency response across the vocal range for uncolored sound
- Supercardioid polar pattern - interchangeable with cardioid and omnidirectional cartridges providing optimal choice for each application
- Sleek, low-profile design for unobtrusive appearance
- Balanced, transformerless output for increased immunity to noise over long cable runs
- Programmable on/off switch and LED on/off indicator
- LED logic input and switch logic output terminals for remote control or use with automatic mixers
