The Sennheiser GA 2-XSW 2 XSW Front Antenna Cables kit (article 507468) lets the antenna connections of an XS Wireless 2 rack receiver be moved to the front of an equipment rack. It contains two antenna front-mount cables and two BNC coupler bulkheads. It is used together with the GA 1-XSW 2 rack-mount kit when an EM-XSW 2 receiver is installed in a 19-inch rack: the short cables run from the BNC antenna sockets on the back of the receiver to the rack ears, where the couplers mount so the supplied rod antennas (or remote antennas) attach at the front. With antennas at the front of the rack rather than hidden behind it, reception is usually more reliable and set-up is quicker for churches, schools, conference venues and bands using a rack-mounted XS Wireless system. The cables are black with BNC connectors. The rack-mount kit, receiver and antennas are not included in this kit. Sennheiser provides a two-year warranty.
