Audio-Technica U841A

This microphone is designed for surface-mount applications where you need clear, unobtrusive audio capture. It excels in professional conferencing, boardrooms, and sound reinforcement scenarios where you want to pick up sound from all directions without the microphone being a visual distraction.

Yes, the U841A offers dual power operation. It can run on standard phantom power (11-52V DC) from your mixer or interface, or you can use a single 1.5V AA battery if phantom power is unavailable.

The UniSteep filter provides a low-frequency roll-off at 80 Hz. This is useful for reducing unwanted rumble or low-end noise, such as HVAC hum or table thumps, without negatively impacting the clarity or natural tone of human voices.

The U841A features Audio-Technica’s UniGuard technology, which is specifically engineered to shield the microphone against radio frequency interference. This helps ensure your audio remains clean even in environments with high levels of wireless traffic.

Because it is a boundary microphone, it is designed to be placed on a flat surface like a table or conference room desk. The microphone uses the surface to create a hemispherical pickup pattern, which effectively captures sound from 360 degrees above the mounting surface.
