ProCo Sound SST Transformers Audio Signal Transformer

ProCo Sound's SST transformer line is built for audio engineers and systems integrators who need reliable signal management between sources and destinations. Whether the application is stage splitting at front-of-house, isolating ground loops in installed systems, or matching impedances across mismatched gear, this transformer family provides a passive, low-profile solution that fits inline without adding active components to the signal path.

Live sound engineers will find the 1:1 isolation and splitting configurations particularly useful for mult boxes, monitor splits, and broadcast feeds, where maintaining signal integrity and eliminating hum from ground differentials is critical. Installed audio and broadcast environments benefit from the impedance conversion options, which bridge consumer and professional gear operating at different impedance levels. The range spans from simple isolation to dual-output splitting and 6:1 or 1:4 impedance conversion, covering the most common transformer requirements in a single product family.

As passive devices, these transformers require no power and introduce no active noise floor, making them a dependable choice when transparency and reliability matter more than features. For integrators standardizing a signal chain or touring engineers building a consistent split system, the SST line offers a range of configurations from a single trusted manufacturer.
