RDL TX-J2 Unbalanced Input Transformer, Unbalanced Stereo Inputs to Summed Balanced Mono Output

Convert stereo unbalanced audio into a single, noise-resistant balanced feed ideal for security and monitoring installations. The Radio Design Labs TX-J2 unbalanced input transformer combines two unbalanced stereo inputs into a summed balanced mono output, providing a simple, passive solution to consolidate audio sources for pro amplifiers, paging, and surveillance systems. Because the TX-J2 performs unbalanced-to-balanced conversion without adding gain, it preserves source level and tone while reducing hum and interference on long cable runs — a key benefit for remote monitoring and security audio channels.

Engineered for installers, the ultra-compact TX series form factor (3" x 1.2" x 1.4") lets you mount the TX-J2 in crowded racks, camera housings, or tight backboards using adhesive STICK-ON methods or conventional chassis mounting. Its durable connectors and RDL quality circuitry make it a reliable choice for continuous operation in security, surveillance, and commercial AV environments. Add the TX-J2 to your next monitoring or surveillance audio design to simplify wiring and improve signal integrity — contact your distributor or order now to integrate it into your system.
