The Electro-Voice RM-300 is a single rack mount kit designed to securely install one R300-RX wireless receiver in a standard 19-inch audio rack. Its bracket can be mounted on either the left or right side of the receiver and features two removable pop-outs for TNC connectors, allowing front-mounted antennas when used with the optional SFMC-300 coax cable kit. The kit includes the required mounting hardware and plastic plugs. Audio rack screws and a T15 Torx driver are not included.
