Do you have a question about the Toa RM-500 and is the answer not in the manual?

The TOA RM-500 is a desktop-type remote microphone designed for general broadcasts, intended for connection to the VX-3000 Series Integrated Voice Evacuation System. This device facilitates clear and efficient communication within a specified environment through its robust feature set and user-friendly interface.

Function Description:

The primary function of the RM-500 is to enable voice announcements and broadcasts to designated zones or groups within a building or facility. It supports broadcasts to up to 80 pre-registered zones, which can be selected via key operation. The device is equipped with a microphone for live announcements and also allows for the control and broadcast of external audio signals through its AUX input. Control output terminals enable the activation of external units, such as sound source equipment, directly from the RM-500. Conversely, control input terminals allow for the activation of arbitrary broadcasts by external triggers. The system incorporates speech intelligibility features, enhancing clarity of microphone announcements even in noisy environments and ensuring appropriate audio signal pickup regardless of the speaker's proximity to the microphone.
