RDL TX-1A Balanced to Unbalanced Transformer, Adjustable

Convert balanced audio lines to unbalanced inputs while removing hum, ground loops and interference — ideal for AV, security and surveillance audio paths. The Radio Design Labs TX-1A balanced-to-unbalanced transformer delivers dependable transformer isolation that preserves signal integrity across monitoring, recording and distribution systems. Its front-access level trimpot provides adjustable output attenuation from 4 to 24 dB, allowing precise level matching and preventing channel overload without changing source settings. The TX-1A accepts either 10 kΩ bridging or 600 Ω terminated inputs, making it flexible for integration with mixers, recorders, access control audio, and field monitoring gear. Built in the U.S. with a compact footprint, this step-down transformer installs easily in tight equipment racks or remote surveillance enclosures and provides long-term reliability in professional AV and security environments. Add the TX-1A to your audio signal chain to simplify system integration and improve monitoring clarity — ideal for installers and system integrators working on security, surveillance, or pro AV projects.
