The RM-500 is a desktop-type remote microphone engineered to support general-purpose broadcast requirements across commercial, institutional, and public sector environments. Designed with reliability and operational clarity in mind, the RM-500 enables users to manage audio announcements with consistency and precision. It is equipped with a backlit LCD screen capable of displaying up to 80 user-defined function names, allowing operators to execute commands through direct key selection. This capability makes the RM-500 highly suitable for applications such as public address systems in transport hubs, educational campuses, healthcare facilities, and commercial buildings where structured audio control is essential.

A key operational advantage of the RM-500 lies in its ability to manage external audio signals independently via the AUX key, ensuring flexible broadcast integration without interference from live microphone use. Additionally, its speech intelligibility function adjusts audio pickup automatically to maintain clarity, even when the speaker’s distance from the microphone varies. This ensures consistent intelligibility in dynamic or high-noise environments. The RM-500 also offers installation flexibility, as it can be mounted on a wall using an optional bracket, making it adaptable to diverse operational layouts. By combining practical audio control with intelligent design features, the RM-500 contributes to enhanced communication efficiency across complex facilities.
