Radial CATAPULT TX4L 4-Channel Cat5 Audio Snake Transmitter Module w/ Line-Level Transformer

MSRP: $250.00
(You save $20.01 )

The Catapult TX4L and RX4L are four-channel line level splitters and isolators that allow you to split four audio channels and transmit them over a single standard cat5 shielded twisted pair cable. This allows you to split line level signals between three different destinations, either on stage or using a buildings existing Cat 5 or Cat 6 cabling to route the signal. Each unit features line level isolation transformers which help to eliminate buzz and hum caused by ground loops, saving hours of troubleshooting. The TX4L has four XLR-F inputs and four isolated XLR-M outputs and feature RJ45 type Ethercon connections with ground lift switches.

The Radial Catapult is a 4-channel audio snake that lets you send analog or AES digital audio signals over standard Cat 5 or Cat 6 shielded twisted pair 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.

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.
