The Audio-Technica U841A captures audio using an omnidirectional polar pattern in a hemisphere above the mounting surface, ensuring even coverage. It features a frequency response of 30 to 20,000 Hz and includes a low-frequency roll-off switch at 80 Hz providing 18 dB/octave attenuation for noise reduction. Phantom sensitivity measures -39 dB (11.2 mV) re 1V at 1 Pa, while battery sensitivity is -40 dB (10.0 mV). It supports phantom power requirements of 11-52V DC with typical current of 2 mA or uses a 1.5V AA/UM3 battery for up to 1200 hours of operation.

This microphone connects via a permanently attached cable with a diameter of 3.2 mm and length of 7.6 m, terminating in a TA3F-type connector that adapts to a 3-pin XLRM output.
