The Azden EX-507XD is a professional-grade upgrade lapel microphone specifically engineered for use with Azden PRO-XD series UHF wireless microphone systems. This microphone is designed to replace the standard lavalier included with many systems, offering a significant improvement in audio quality, durability, and performance for demanding broadcast, film, and presentation applications. At its core is a high-quality, miniature omnidirectional electret condenser capsule, renowned for its ability to deliver a natural, articulate, and transparent sound with a smooth, extended frequency response. Its omnidirectional pickup pattern is ideal for close-miking applications, capturing the voice consistently even with slight head movements by the talent, which is crucial for maintaining consistent audio levels during interviews, live reports, or theatrical performances.

The EX-507XD features a professional, low-profile metal casing that ensures durability and provides effective RF shielding. It terminates in a locking mini-plug connector designed to mate securely with Azden's PRO-XD bodypack transmitters, preventing the accidental disconnections that can plague standard connectors when cables are tugged or snagged. This secure connection is vital for live broadcasts and event recording where a single audio dropout is unacceptable. The microphone is supplied with a comprehensive set of accessories for versatile mounting, including an alligator clip, a tie clip, and adhesive pads for skin or fabric application, along with a high-density foam windscreen to effectively reduce plosive sounds and moderate wind noise.

As an upgrade component, the EX-507XD is intended for audio professionals who require the highest level of performance from their wireless systems. Its superior capsule and robust construction yield clearer, more detailed audio with lower self-noise compared to entry-level lavaliers. When paired with a PRO-XD wireless system, it forms a complete, high-fidelity solution for talent who need discreet, hands-free operation without compromising on sound quality. This microphone is a trusted tool for sound engineers and videographers working in news gathering, documentary production, corporate video, and any scenario where reliable, broadcast-quality lapel audio is a necessity.
