The Radial Catapult TX4 is a modular snake system that drives four analog or AES audio channels over a single shielded Cat 5 cable. The Catapult enables system contractors to take advantage of pre-wired networks to connect one room to another, and allows live sound technicians to take advantage of the low cost of Cat 5 cable for return or cross-stage snakes. The modular Catapult is available in six configurations with a choice of three input and three output modules. Each input module includes four XLR-F inputs, four XLR-M outputs and two Neutrik Ethercon™ outputs. Each output module features an Ethercon input, a throughput and two sets of four XLR-M outputs. Modules can be ordered without transformers for sub-snakes or to transmit AES digital signals; with mic isolation transformers to provide split outputs for FOH, monitors or a recording system; or with line level isolation transformers to eliminate system noise. Ground lift switches are provided at each end of the Ethernet cable connection to help eliminate hum and buzz caused by ground loops.
