The Neutrik 3-pin impedance transformer is designed to convert a female 110ohmXLR interface to female 75ohm BNC interface. This allows the use of a 75ohmvideo cable for longer cable runs. It also means that digital audio signals can be patched using industry-standard MUSA video patch panels and distributed using video distribution amplifiers.
Warning:
Not to be used as mains connectors.

Allows long cable runs for digital audio signals via low attenuation coax lines
Avoids the need for new installations or temporary cable runs
Electrical rating is 5V, 250mW
Match balanced to coaxial lines
Match impedances between 75ohm and 110ohm
Chassis mount
Operating temperature ranging between -30°C and 80°C
Simple to use, passive unit
