Engineered for Perfect Speech Capture

The Electret condenser gooseneck microphone has a cardioid polar pattern and slimline profile design. The microphone is constructed from high quality brass construction using an 8mm flexible shaft. The microphone is fitted with a phantom power adaptor accepting 9 to 48 volts DC and has an impedance of 200 Ohms.

The Phantom Power Adaptor includes filters which will eliminate all cellular frequencies (GSM/2G, 3G, 4G & 5G) and is terminated with a male 5 pin XLR. Frequency response 50 Hz – 18 KHz +/-3dB, sensitivity -37dB +/- 3dB @ 1KHz (0dB =1V/Pa), total harmonic distortion (THD) at an operating level of 120dB less than 1%. The microphone head includes an integral concentric Halo illuminated by high brightness LED’s drawing 30mA max at 12 Volts.

The LED’s will require a separate 12 Volt DC power source. Gooseneck Dia: C 31→C 34 – 8mm, C 35 &
