FOX PDI-2 Direct Box——S-Track S TRACK SCIENCE TECHNOLOGY CO., LTD

صندوق التوصيل المباشر FOX PDI-2

This is a professional dual-channel passive impedance converter (Direct Box) designed for live performances, recording studios, and AV system integration. Featuring dual professional-grade audio transformers, it enables seamless conversion from high-impedance unbalanced inputs to low-impedance balanced outputs. Supporting stereo signal processing, it effectively eliminates ground loop noise and EMI interference, ensuring distortion-free transmission over long cable runs (>100 meters). Built-in active attenuators and floating ground functionality facilitate matching high-output sources such as keyboards, synthesizers, and active instruments. Offering an exceptional balance of durability and audio fidelity, this unit is ideal for professional musicians and sound engineers.
