ProCo Sound PRX XLR Polarity Reversal Adapter Female to Male

The ProCo Sound PRX is a passive inline adapter engineered for audio engineers who need to reverse signal polarity on XLR mic or line-level circuits without patching in a console or outboard processor. Its female-to-male XLR configuration drops directly into any standard XLR signal chain, making it a practical tool for live sound, broadcast, and installed audio environments where phase relationships between sources need fast, reliable correction.

For live production engineers managing multiple microphones on a single source — such as top and bottom snare mics, or paired cardioids on a piano — polarity misalignment can cause significant comb filtering and signal cancellation. The PRX addresses this at the cable level, removing the need to rely on console polarity invert buttons that may not always be accessible or recallable. System integrators and broadcast engineers will find it equally useful during signal verification and diagnostic workflows.

Unlike software phase correction or DSP-based solutions, the PRX introduces no latency and requires no power, making it a dependable and permanent solution for fixed installations or a compact addition to any touring engineer's toolkit.
