Description N/A
  • 6 mm overall diameter and 2.2 mm height with pin terminals
  • -42 dB sensitivity for use in most environments
  • Wide 2 to 10 VDC operating voltage and 50-16000 Hz frequency range
  • >60 dB signal to noise ratio and 2.2 kOhm impedance
  • Omni-directional polar pattern for great off-axis response
  • Internal 33 pF capacitors filters out GSM TDMA noise
N/A N/A PUI Audio??s all-new HD Series microphones use premium-grade FETs and diaphragms for high sensitivity and superior signal-to-noise ratio. Each microphone features GSM buzz-blocking capacitors. Upgrade the ECM microphone that you use today with a PUI Audio HD Series microphone.

The 6 mm diameter POM-2730L-HD-R is designed for extreme fidelity from 20 Hz to 20 kHz.
