Remote Microphone

RM-500 Y

The RM-500 is a desktop type remote microphone for general broadcasts.Equipped with an LCD screen, it can display up to 80 function names registered in advance, allowing these functions to be executed with the key operation.The AUX key allows only the external audio signals to be controlled regardless of whether the microphone broadcasts are present or not. 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 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 an optional wall mounting bracket.
