Sound Barrier SIAMESE50 — Standard Siamese Twin AC Audio Interconnect Cable
SIAMESE50 Overview
The Sound Barrier SIAMESE50 is a Siamese Twin Powered Speaker Interconnect Cable engineered to carry both AC power and balanced audio signal in a single cable run, eliminating the need for separate power and audio lines to portable powered monitors. The assembly features an IEC Female to Edison Male AC connection paired with a single channel of AES/EBU-compatible balanced audio via XLR3M to XLR3F. Shielded AC and double-shielded audio lines work together to fully eliminate electronic interference below 100Hz, addressing the most common sources of hum and buzz in live sound environments. This cable is an efficient solution for audio engineers, touring companies, and production crews who regularly deploy powered monitors in live or installed settings.
The rugged, flexible construction is designed to withstand the demands of repeated fast set-ups and tear-downs, reducing cable management complexity on stage and in the field.
Key Features
- Combined AC and Balanced Audio — Carries AC power and one channel of balanced XLR audio in a single cable assembly, streamlining powered monitor deployment
- Shielded AC Line — AC conductor shielding suppresses radiated interference that commonly induces hum into audio signal paths
- Double-Shielded Audio Line — Dual-layer shielding on the audio conductor eliminates electronic interference below 100Hz for clean signal transmission
- IEC Female to Edison Male AC Connectors — Standard IEC-style female and Edison male terminations for broad compatibility with powered speaker inputs and standard AC outlets
- XLR3M to XLR3F Audio Terminations — Industry-standard three-pin XLR connectors for reliable balanced audio connectivity compatible with AES/EBU signal standards
- Rugged, Flexible Construction — Cable jacket designed for repeated coiling, uncoiling, and physical stress associated with touring and live production workflows
- Single-Run Efficiency — Reduces cable count, simplifies stage layout, and speeds up set-up and tear-down for portable monitor systems
