The Audio-Technica ES925/XLR is a modular microphone system designed for professional sound reinforcement and other commercial sound applications. It includes a condenser microphone element, gooseneck, and an XLR power module. The ES925C21/XLR is an 18" cardioid condenser gooseneck microphone with an XLR power module.
Each component is interchangeable with other ES modular microphone components, allowing you to mix and match power module types (XLR, FM3, FM5, DS5), gooseneck lengths (4.85", 9.08", 12.08", 15.08", 18.08", 21.08"), and microphone polar patterns (MicroLine®, hypercardioid, cardioid, omnidirectional).
