The Soundtools Cat Box (2 Female, 2 Male) is a compact, passive audio signal converter designed for sending and receiving audio signals over a single Ethernet cable (Cat5e, Cat6, etc.). It features two female and two male XLR connections, allowing for two independent signal sends and two signal returns over four shielded twisted pairs of a single cable. This is particularly useful for reducing cable clutter and simplifying stage or studio setups. The device is passive and does not require external power.
