Sony ECM-90LM Ultra-Miniature Lavalier Microphone with Lemo Connector
The ECM-90LM is the Lemo-terminated version of Sony's ultra-miniature lavalier. Mechanically and acoustically it is the ECM-90: a one-gram dual-diaphragm omnidirectional capsule with a flat 20 Hz to 20 kHz response, 99 dB of dynamic range, and a diaphragm mount designed to keep cable handling out of the audio. What changes is the tail.
A three-pin Lemo connector on a 1.6 metre cable makes it a drop-in for the bodypacks that use that standard, and power comes from the transmitter rather than a separate supply. Choose this one when the wireless in the rack is not Sony's four-pin type. Windscreens and a set of vertical, horizontal and safety clips ship with it.
