Sound Barrier UMXL12 — 3.5mm TRS to Dual XLRM Stereo Breakout Cable
UMXL12 Overview
The Sound Barrier UMXL12 is a 12-foot stereo breakout cable designed to route a 3.5mm TRS stereo output to two discrete XLRM connections, making it a practical solution for interfacing consumer and prosumer devices with professional balanced audio systems. Built with 27-gauge Oxygen-Free Copper (OFC) conductors and a 90% OFC braided shield, the UMXL12 prioritizes signal integrity and noise rejection in demanding environments. Polyethylene (PE) insulation protects the conductors and contributes to consistent electrical performance across the cable’s length. Each cable is individually tested for performance and quality before leaving the factory, making it a dependable choice for audio engineers, system integrators, and touring professionals.
The UMXL12 is well suited for connecting laptops, tablets, portable media players, or audio interfaces with 3.5mm outputs directly into mixing consoles, stagebox inputs, or other XLR-equipped equipment without the need for additional adapters.
