The Azden EX-503L is a professional omnidirectional lapel microphone engineered for discreet, high-fidelity vocal capture in broadcast, presentation, and live performance applications. Its core component is a miniature electret condenser capsule designed to deliver a natural and transparent sound with a wide frequency response. The omnidirectional pickup pattern captures sound evenly from all directions, which is ideal for close-miking applications where the microphone is positioned very near the sound source. This pattern ensures consistent audio quality even if the speaker turns their head slightly, making it exceptionally reliable for talent who move during interviews, theatrical performances, or instructional videos. The microphone is terminated with a professional locking 3.5mm mini-plug connector, which features a threaded collar that screws securely onto compatible bodypack transmitters, preventing accidental disconnection that could compromise a live broadcast or recording.

Housed in a durable, low-profile metal casing, the EX-503L is designed for inconspicuous placement on clothing. It is supplied with a versatile set of mounting accessories, including an alligator clip for fabric, a tie clip, and adhesive pads for securing the microphone to skin or non-cloth surfaces. A high-density foam windscreen is included to effectively reduce plosive sounds and moderate wind noise, ensuring clean audio capture in a variety of environments. The attached cable is of a premium, flexible quality that minimizes handling noise and is designed for long-term reliability, resisting tangles and maintaining signal integrity.

This microphone is specifically designed for integration with professional wireless systems that feature a matching locking 3.5mm input jack, commonly found in bodypack transmitters used in broadcast and film production. The combination of broadcast-grade audio performance, a secure physical connection, and practical mounting solutions makes the Azden EX-503L a trusted tool for sound professionals. It ensures a dependable audio link that captures clear, intelligible dialogue, meeting the stringent standards required for television, documentary filmmaking, corporate communications, and any scenario where reliable, hands-free vocal reinforcement is critical.
