Audio Solutions Question of the Week: How Do I Change the Element In an A-T Boundary Microphone?

Question: How do I change the element in an A-T boundary microphone?

Answer: Many of the hanging, gooseneck, and boundary microphones in Audio-Technica’s popular UniPoint® and Engineered Sound lines have interchangeable elements, allowing you to use different microphone elements in the same microphone casing for a variety of pickup options. There are three interchangeable elements available for UniPoint boundary mics: UE-C (cardioid), UE-H (hypercardioid), and UE-O (omnidirectional). And there are three elements available for Engineered Sound boundary mics: ESE-C (cardioid), ESE-H (hypercardioid), and ESE-O (omnidirectional). (Note: UniLine and MicroLine elements are not usable with boundary microphones due to the length of the elements.)

IMPORTANT: To keep your UniGuard® RFI immunity intact, be certain when replacing the wire mesh in step 5 that it fully covers the opening and makes contact with the metal edges of the chassis.

You may use the same A-T sticker that was removed in step 1 or get a replacement sticker through our Parts Department by contacting them at Parts@atus.com or at (330) 686-2600 ext. 5002.
