General remote microphone with LCD

The RM-500 is a desktop type remote microphone for general broadcasts in the VX-3000 system. Equipped with an LCD screen, it can display up to 80 function names registered by the installer, allowing these functions to be executed with the key operation. The AUX key allows the external audio signal connected to the remote microphone to be broadcast in selectable zones. The speech intelligibility function makes it easier to hear the microphone announcements even in noisy environments, and also allows the microphone to pick up the wanted audio signals at an appropriate level even if speaking too close to or too far from it. The RM-500 can be mounted on the wall by using the optional wall mounting bracket WB-RM500.• Desktop Remote Microphone with LCD for general broadcasts
