The Azden AZDEN-EX-507XD is a premium upgrade lavalier microphone specifically engineered for use with Azden's 500-series PRO-XD UHF wireless systems, though it maintains compatibility with any professional wireless bodypack transmitter featuring a standard 3.5mm (1/8-inch) locking microphone input. This microphone is designed to deliver superior audio quality for broadcast, theatrical, and high-end presentation applications where the standard supplied lavalier may not meet demanding acoustic requirements. It features a miniature omnidirectional electret condenser capsule that provides a smooth, natural frequency response tailored for speech, with enhanced clarity in the presence range to ensure intelligibility even in noisy environments. The microphone's low-profile, cylindrical metal housing is designed to minimize clothing rustle and is effectively shielded against radio frequency interference (RFI), a common issue when using wireless systems in electronically dense areas.

A key professional feature of the EX-507XD is its integrated, detachable cable terminated with a right-angled 3.5mm locking mini-plug. This plug securely connects to compatible bodypack transmitters via a twist-lock mechanism, preventing accidental disconnection that could occur during vigorous talent movement. The cable itself is of a premium grade, utilizing high-strand-count, oxygen-free copper conductors within a durable, flexible jacket that resists kinking and maintains signal integrity. The microphone operates on standard plug-in power (typically 3-5V) supplied by the wireless transmitter and includes a built-in, pre-emphasis circuit that is optimized to work in tandem with the de-emphasis curve in Azden PRO-XD receivers, resulting in a flatter overall frequency response and reduced noise.

The microphone is supplied with a comprehensive set of professional mounting accessories, which may include a sturdy metal tie clip, a magnetic mount for quick placement without piercing delicate fabrics, an alligator clip, a foam windscreen, and a protective carrying case. These accessories allow sound engineers to securely and discretely position the microphone on a wide variety of attire. With its focus on broadcast-grade audio performance, robust construction, and secure connection, the Azden EX-507XD serves as a critical upgrade for users of Azden PRO-XD systems and other professional wireless setups, providing the enhanced vocal clarity and reliability needed for mission-critical applications in news gathering, corporate videography, and live performance.
