The U841A from Audio-Technica is an omnidirectional condenser boundary microphone for surface-mount applications. Offering a frequency range of 30 Hz to 20 kHz, this microphone works with an AA battery as well as phantom power, offers a dynamic range of over 100 dB, and boasts an SPL of 123 dB to 133 dB depending on the method of power used.
Designed for surface-mount applications such as sound reinforcement, conferencing, television sound, and more
Rejection of RFI (radio frequency interference) through UniGuard technology
Small-diameter capsule near boundary for eliminating phase-distortion whilst delivering a high-output signal
Steep low-frequency attenuation for increased sonic response without affecting vocal quality
Non-slip silicone foam pads minimize coupling and other problems due to surface-to-surface microphone vibration
