ProCo Sound 9144PC Lo-Z to Hi-Z Transformer Signal Adapter

The ProCo Sound 9144PC is a passive transformer adapter designed for audio professionals who need to bridge the impedance gap between low-impedance microphone sources and high-impedance instrument-level inputs. This is a common requirement in live sound and studio environments where a mic-level signal must feed a guitar amp input, a DI return, or a high-Z effects device without distortion or level mismatch.

With its TS output and XLR female input, the 9144PC fits naturally into signal chains where a standard passive solution is needed without a dedicated DI box or preamp in the path. For engineers, integrators, and production technicians managing complex signal routing, this adapter provides a compact, reliable conversion point that eliminates the need for additional active hardware. The transformer-based design ensures proper impedance matching rather than a simple level pad, preserving signal integrity at the conversion stage.
