English: The BAE Audio PDI is a high-performance passive direct injection box designed to convert high-impedance unbalanced signals into low-impedance balanced signals. It features a hand-wired signal path utilizing a premium OEP/Carnhill audio transformer to impart a warm, analog character with harmonic richness. The circuit includes gold-plated traces and through-hole component technology for maximum signal integrity and reliability. Its rugged steel chassis is built with recessed switches and connectors to withstand heavy use in both studio and stage environments. Unique to this design is the inclusion of dual through outputs, allowing for versatile routing to multiple amplifiers or signal chains.
