Wireless Microphone Systems

Wireless microphones give presenters the freedom to move, gesture, and engage an audience without being tethered to a podium. At Astro Audio Visual, we provide enterprise-grade wireless microphone systems that deliver rock-solid RF performance in even the most congested radio environments. From single-presenter keynotes to multi-panelist discussions with a dozen open channels, we ensure every voice is captured with studio-quality clarity.

Our wireless inventory spans handheld, lavalier (clip-on), and headset form factors, allowing us to match the right microphone to each presenter's comfort level and performance style. For panel discussions, we deploy gooseneck or boundary microphones at the table while keeping wireless lavalieres as backups. Every system operates on digitally encrypted frequencies, preventing eavesdropping and interference from competing wireless traffic in the venue.

RF coordination is where our expertise truly shines. Before every event, our engineers perform a comprehensive spectrum scan of the venue, identifying occupied frequencies from in-house systems, nearby broadcasters, and other events running simultaneously. We then assign clean channels with adequate intermodulation spacing, program frequencies into our receivers, and run a walk-test to verify dropout-free coverage across the entire stage and audience area. The result is a wireless experience so reliable that presenters never think about the technology — they simply speak, and the audience hears every word.
