Architects and engineer specifications The condenser microphone is of a very low profile boundary layer through table design, with a cardioid polar pattern. 2 Independently powered microphone capsules are inbuilt into the housing. The microphone has a unique ability to retract and lock the capsule module away from sight leaving only 3 mm (0.12”) protruding on top of the table. The microphone is of a robust brass construction and includes 2 metres (6.6ft) of cable. Included is an integral phantom power module which requires 9 to 48 volts. The Phantom Power Adaptor includes filters which will eliminate all cellular frequencies (GSM/2G, 3G, 4G & 5G). Impedance 200 Ohms; Frequency response 50 Hz to 18 KHz; Sensitivity -37dB ± 3dB @ 1KHz (0dB =1V/Pa); Total Harmonic Distortion (THD) at an operating level of 125dB is no greater than 1%. Finish: Black Nextel® or Satin Nickel.
