The ETS PA901 is a digital audio time code balun with BNC-F to XLR-F connection.
The ETS PA900 series of baluns from ETS is designed to connect Time Code signals from XLR output equipment to standard 75Ohm coax or 100Ohm UTP cabling systems. The baluns perform precise impedance-matching and signal balancing, enabling Time Code signals to be transmitted with greater signal integrity and longer runs over coaxial or UTP cable than can be achieved with conventional STP wiring.
