The MuxLab Stereo RCA/Phono Hi-Fi Balun allows an unbalanced line-level analogue audio signal to be transmitted via a single Cat5e/6 cable up to a distance of 1km/3250ft/620m.

With a frequency range of 20Hz - 20'000Hz, the Balun can be used for any application with no frequency or sound quality loss.

The Balun is passive and requires no mains power. This does mean it's only suitable for use with powered equipment, it's not compatible with passive speakers or microphones for example.
