Microphone condensor measurement Mellab myc-3 with Free field frequency response, 0°, +/- 1dB : 10-10000 Hz and Free field frequency response, 0°, +/- 2dB : 10-22000 Hz. It has a Sensitivity (@ 250Hz; +/-2 dB) of 15 mV/Pa [-36.5 dB re 1 V/Pa] and Max SPL (THD<3 %) of 140 dB SPL. Noise is less than 23 dBA SPL equivalent (typically 22 dBA). The microphone operates in temperatures ranging from +0.035 dB/°C-10 °C to +50 °C (14 to 122 °F). It features a balanced output impedance of 30 ohm, omnidirectional polar pattern, and requires 48V [5 mA] phantom power. It weighs 68 grams and has a length of 116 mm.
