The Radial Catapult Rack RX is a passive, rack-mount audio snake designed to receive up to twelve channels of analog audio over standard Cat 5 or Cat 6 Ethernet cables. It functions as the receiving end of the Catapult system: you simply connect three shielded Cat 5/6 cables to a matching Catapult Rack TX or other compatible Catapult modules, and each cable carries four balanced audio channels without any digital conversion. The unit is built ruggedly with a steel chassis and locking etherCON RJ-45 connectors, and includes three ground-lift switches (one per four-channel bank) to eliminate noise caused by ground loops. The reversible rack ears let you configure whether the XLR connectors or Ethernet jacks face outward, offering setup flexibility in tight stage or studio environments. Operating entirely passively, this module requires no power and maintains pristine analog audio quality through straight-wire connections.—adapted from Radial support materials and reviews.
