The CAT Tails MX from SoundTools allows four lines of balanced analog audio, AES/EBU, DMX, and Clear-Com signals to be run down a shielded etherCON/Cat 5/6/7 cable hundreds of feet away. The CAT Tail is a fully passive unit that supports 48V phantom power and can be used for input directly into analog or digital consoles. Each channel is isolated, which means channel 1 can send a DMX signal while channel 2 is sending balanced analog all down the same shielded Cat 5 cable.
Additionally, the CAT Tails extension system consists of a male XLR sender and a female XLR receiving unit (both sold separately). This allows you to send four XLR audio signals thru a Cat 5/6/7 cable hundreds of feet away and convert it back to the four XLR balanced analog audio, AES/EBU, DMX, and Clear-Com signals.
