Shure MX396/C-TRI Microflex Tri-Element Boundary Microphone

MX396/C-TRI Microflex Tri-Element Boundary Microphone description:

The Shure MX396/C-TRI Microflex Multi-Element Boundary Microphone. Versatile, three pattern coverage boundary mic that delivers exceptional sound quality.

The Shure MX396/C-TRI Microflex Multi-Element Boundary microphone delivers a unique and versatile tool for conference room installations. Clean and simple in appearance, Multi-Element Boundary mics come in two or three element configurations, combining the coverage of multiple microphones into one small, compact package. This MX396/C-TRI model features a Tri-Element 90-0-90 mic, adjustable to 120-120-120 degrees via three cardioid polar pattern elements, each with individual channel output, back or bottom exit cable, mute output and LED input. Microflex microphones include the highest standard of quality and efficiency for installed audio applications. All models offer Shure CommShield Technology, which guards against unwanted radio interference from consumer wireless devices such as cell phones and PDA’s.
