Description
Boundary microphone provides high-quality sound for a wide range of applications due to its interchangeable condenser cartridge. It features programmable, silent membrane switches, LED indicators, and a low-profile design.
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.
Features:
- Flat frequency response across the vocal range for uncolored sound
- Interchangeable cartridges that provide a choice of polar pattern for each application
- Sleek, low-profile design for surface mounting
- Programmable mute button
- LED indicator
- Logic input/output for remote control or use with automatic mixers
- RF filtering
The polar pattern of the included cartridge is indicated by a model number suffix:
