A scalable wireless microphone system lets installers expand from a small setup to a multichannel deployment by linking receiver chassis and supporting up to 20 channels. Each receiver can pair with multiple handheld, body-pack, desk stand, or boundary transmitters, allowing teams to match microphone types to the room and project needs.

Standard mode supports up to ten channels and is designed to minimize latency, while high-density mode supports up to twenty channels to maximize system capacity. The right setting depends on whether the installation prioritizes lower latency or accommodates more simultaneous transmitters.

Receivers can remain docked in a half-rack chassis or be mounted remotely over Ethernet cable, with each receiver supporting up to four transmitters. Installers can link up to five chassis with RJ12 cabling to build a multichannel system, while assigning handheld, body-pack, desk stand, or boundary transmitters to receiver channels as needed.

Audio-technica System 20 PRO includes handheld, body-pack, desk stand, and boundary microphone transmitters for presentations, conferences, performances, and other professional audio applications. Body-pack transmitters support lavalier and headworn microphones, while desk stand and boundary transmitters suit meeting rooms, lecture spaces, and panel discussions.
