ProCo Sound CXF Audio Isolation and Impedance Transformer

The ProCo Sound CXF is a 1:1 output isolation transformer designed for audio engineers, system integrators, and production teams who need reliable signal isolation in demanding live sound, installed AV, and broadcast environments. It addresses the common challenge of ground loops and noise introduced when interconnecting professional audio equipment across multiple power sources or chassis grounds.

ProCo Sound's transformer lineup serves a wide range of signal management needs, from basic output isolation to impedance conversion and signal splitting. The CXF fits squarely into signal chain applications where maintaining signal integrity between sources and destinations is critical — such as stage boxes, patch bays, broadcast feeds, and installed audio systems with multiple ground planes.

Compared to active DI solutions, passive isolation transformers like the CXF introduce no additional noise floor from power supplies and require no external power, making them a dependable choice in complex installations where simplicity and reliability are priorities. ProCo Sound's long-standing presence in professional audio ensures the CXF meets the practical demands of working engineers and integrators.
