Overview
When you need a reliable way to feed mixers, subwoofer amps or monitoring systems from a power amplifier, the Radio Design Labs TX-8A delivers professional-grade performance and protection. This single-channel transformer interface converts 4 or 8 ohm speaker outputs to line-level signals while providing galvanic isolation to prevent ground-loop hum and safeguard sensitive audio inputs. A high-quality bifilar-wound audio transformer preserves wideband clarity and low distortion, and the front-panel LEVEL control lets you set output to -10 dBV or +4 dBu for consistent levels across installations. The TX-8A accepts amplified levels from 0.5 W up to 400 W, and its secondary can be wired balanced or unbalanced for flexible routing into mixers, recorders or surveillance audio processors. Small and rack-mountable, it installs where you need it and pairs easily with other RDL modules for scalable audio distribution. Ideal for AV, security, surveillance and live sound applications, the TX-8A reduces noise issues and simplifies system integration. Add the TX-8A to your system to protect downstream equipment and ensure clean, professional line-level audio—order now or contact us for integration guidance.
