The JBL SRX900 RC1 is a universal rain cover used for protecting SRX900 amplifier modules from moisture. The rain cover attaches to the amplifier module using the five included M3.5 fasteners and covers the LCD, XLR and etherrCON® connectors. A Velcro feature allows easy access to the LCD and connectors, while cover's flexible material allows it to drape around the connected cables. Once attached, the RC1 is designed to remain on the product; it does not need to be removed for indoor applications. The RC1 should always be used when SRX900 products are used outdoors. Note that the Neutrik powerCON® TRUE1® TOP power connectors are IP65 rated, and do not need to be covered for outdoors use. For more information on how to attach the RC1, refer to the SRX900 Series Rigging and User Manuals.
