Radial CATAPULT RX4 4-Channel Cat5 Audio Snake Receiver Module

MSRP: $150.00
(You save $10.01 )

The Catapult TX4 and RX4 are four-channel audio snakes that allow you to send analog and AES digital audio signals over standard Cat 5 shielded twisted pair cable. This allows for the use of existing Cat 5 or Cat 6 cable infrastructure to connect audio signals from one part of a building to another, or to run sub-snakes over long distances with inexpensive and lightweight cable. This allows stage techs to take advantage of the relatively low cost of this abundantly available cable for return snakes or for transporting balanced audio across a large stage. For the system contractor, the Catapult lets you take advantage of pre-wired networks to connect audio from one room to another.

The RX4 has two sets of four XLR-M outputs and features an RJ45 type Ethercon input and thru-put, and include ground lifts to help eliminate buzz and hum caused by ground loops. The rugged design, exceptionally flat frequency response, and low noise make the RX4 an excellent option for analog or AES audio in critical situations.

As with all Radial products, the Catapult is constructed with solid 14-gauge steel to handle the rigors of live touring and is finished in a powder-coat finish to keep your Catapult looking good for years! Inside, a two-sided PCB is used to mount the connectors and transformers doubling up the solder joints for maximum durability.
