CLOCKAUDIO C012E-RF Through Table Cardioid Boundary Layer Mic. Came out of a working conference room. For conferences room tables, video conference systems.  Good for court room, church, conference boardroom, video conference systems. I have 14 available complete with grommets and nut.

Specs: Condenser microphone design is for a through desk/ceiling/panel mount boundary layer type with a cardioid polar pattern. The microphone is made of a robust high quality brass construction with a low profile robust brass top. It is terminated with a male 3 Pin XLR. The microphone is powered by a 9 to 48 volts phantom power adaptor. The Phantom Power Adaptor includes filters which will eliminate all cellular frequencies (GSM/2G, 3G, 4G & 5G). Frequency response 50 Hz to 18 KHz; Sensitivity -37dB +/- 3dB @ 1Khz (0dB=1V/Pa) Impedance 200 Ohms. Total harmonic distortion (THD) at an operating level of 120dB is no greater than 1%. Also included are rubber shock mounts to minimize the transfer of mechanical noise from table, ceiling or panel. Length 90.00mm (3.55").
