4 Eaton MEDC SonixTM Public Address General Alarm Let us introduce our patented revolutionary SonixTM platform from MEDC

The SonixTM PA/GA system has been developed and manufactured with inbuilt flexibility for oil, gas, petrochemical and power industries. Its flexibility comes from a universal communication format which allows information to be transmitted between the product, whether local or distributed. This information flow is transmitted via CAT6 cables which also provides a fast, secure and efficient interconnection system. To ensure reliability, these communication paths are fully duplicated, with auto switch over on data loss or corruption. As new products are developed, the new data generated can be easily integrated and targeted to units that need it.

At the heart of the system is This software is completely a patent protected dual path passive and isolated from 92% high efficiency amplifier, critical system operation, but enclosed within a compact 1U provides a convenient way to case. This amplifier continues monitor the detailed status of the flexibility out to the field the system. This allows the by monitoring for both radial or software to be located offsite loop speaker runs.
