MX395B/BI-LED Microflex Miniature Boundary Microph description:

The Shure MX395B/BI-LED Microflex Miniature Boundary Microphone, Bidirectional, Black with 5-pin XLR connector and Bi-Color Status Indicator Ring. A discreet and stylish boundary mic that delivers exceptional sound quality.

The Shure MX395B/BI-LED Microflex Low Profile Boundary microphone is an ideal table microphone when minimal presence is of high priority. Perfect for meeting rooms, MX395 microphones deliver exceptional sound pickup whilst barely being noticed. This MX395B/BI-LED model features a Bidirectional polar pattern, a Black finish, a 5-pin XLR connector, logic-controlled muting functions and Bi-Color Status Indicator Ring. 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.
