The ToneWinner PX-1 is a balanced interconnect from Guangzhou Tonewinner Electronics, terminated with a male XLR plug at one end and a female XLR socket at the other. Tonewinner supplies it in pairs at a standard length of 1.5 m, and the cable is meant to link a source, preamplifier or processor to a power amplifier or active monitor over balanced lines.
The conductors are multi-strand 6N OCC copper, a single crystal oxygen-free copper drawn to a purity of 99.9999 percent, which reduces the number of grain boundaries along the signal path. A full shield surrounds the conductors to keep external interference away from the balanced signal. Tonewinner also offers the PX-2 as a second balanced XLR model.
