Rondson - MIC-404

The MIC-404 is a multi-zone, desktop call microphone designed to work with the Rondson MX-404 preamplifier.

It features a unidirectional microphone and allows the selection and management of (up to) four independent zones using dedicated controls. It includes a chime activation switch and a priority / slave switch, allowing use in systems with call priority. The “Talk” button activates the microphone signal and automatically enables the 24 V input on the amplifier, activating the priority mode.

Up to thirty-two MIC-404 microphone stations can be daisy-chained using UTP-CAT5 cabling with RJ45 connectors, simplifying installation. Advanced features include surge protection, faulty microphone detection and a power saving system in stand-by mode.

It includes a DC adapter power input and integrates a low voltage detector, ensuring reliability even in unstable power conditions.
