use in boardrooms and other sites where aesthet- ics are important. The MX395 is only 2.5 cm (1 in.) in diameter, and extends just 2 cm above the mounting surface when installed. Despite its small size, the MX395 delivers clear, high quality sound. Features • Low profile, aesthetic design • Wide dynamic range and smooth frequency response • RF filtering with CommShield® technology • Available with logic-controlled bi-color status indicator Model Variations The MX395 is available in cardioid, omnidirection- al, and bidirectional polar patterns, with or without an LED status indicator, with a black, white, or aluminum finish. Furnished Accessories Wing Nut Rubber Isolation Ring 5-pin XLR, Female (MX395-LED variations) 65A2190 66A405 95A2529 Polar Patterns The polar pattern is indicated by the molded grille. Cardioid Omnidirectional Bidirectional Microphone Placement For best low-frequency response and rejection of background noise, place the microphone on a large, flat surface, such as a floor, table, or lectern. To reduce reverberance, avoid reflective surfaces above or to the side of the microphone, such as beveled sides of pulpits or overhanging shelves. MX395/C 130° @ -3dB MX395/BI 2 x 90° @ -3dB MX395/O 360° Installation Install the microphone into a tabletop as shown. Important: • Align indentation toward talker • Do not over tighten the wing nut, as this reduces shock isolation DIP Switches Set DIP Switch 1 up to engage the low cut filter, which attenuates frequencies by 6 dB per octave below 150 Hz.

Note: Connect the LED IN to the gate output to il- luminate the LED when the channel is gated on. Do not use the relay ports on Crestron and AMX devices. Use the I/O logic ports instead. The LED logic may not function when connect- ing to devices that do not have internal "pull-up resistor" logic circuits, such as ClearOne DSP products. External pull-up resistor circuits can be added for each microphone. Vistit www.shure. com/FAQ for detailed instructions. 4 2 5 1 3 Audio − Audio + Logic (LED IN) 5-Pin XLR +5 V Green LED 0 V c.c. 5 V c.c. +5 V Red LED 4
