RDL TX-AT1S Audio Isolation Transformer with Suppression

Keep critical audio paths clean and protected in pro-audio, security and monitoring applications with the Radio Design Labs TX-AT1S audio isolation transformer. Designed for installers and system integrators, this Max-TX module provides galvanic isolation to eliminate ground-loop hum and preserves signal integrity between balanced equipment. The unit uses a studio-grade 1:1 audio transformer with 600 Ω primary and secondary bifilar windings, delivering wideband response, ultra-low distortion and the headroom needed for mixers, recorders and surveillance audio channels.

The TX-AT1S combines transformer coupling with solid-state transient suppression and ferrite RF filtering to defend inputs and outputs from harmful impulses and radio-frequency interference—critical in security, monitoring and AV installations. Barrier-block terminations and the ability to wire primary or secondary unbalanced make it easy to adapt balanced-to-unbalanced conversions on the fly. Its compact Max-TX form factor and optional rack or surface mounting provide installation flexibility in racks, equipment rooms or remote enclosures.

Add the RDL TX-AT1S to your system to improve audio clarity and protect downstream gear—ideal for pro-audio, surveillance and monitoring deployments. Order now to secure cleaner, more reliable audio links.
