This adapter pair is designed to send stage light or audio signals to a remote mixer or light desk, reducing cable clutter and overall costs. - Four-channel analog XLR transmission over RJ45: Two adapters transmit 4 analog XLR signals via a single RJ45 network cable. Connect the mixer, microphone, and instrument to the XLR inputs, and forward all four channels to the remote unit through a shielded, balanced Ethernet cable. RJ45 cable not included. - Compatibility and performance: Works with other 3-pin XLR systems and line level sources. Provides balanced transmission and clear, high quality sound with minimal residual noise in varied indoor and outdoor environments. - Interference suppression and signal integrity: Uses a unique impedance conversion transmission and analog audio spread spectrum isolation technology with anti interference properties. Effectively solves distortion and audio noise caused by long audio runs or earth potential difference (ground loop) currents, eliminating background noise. - Use scenarios: - In theaters or large venues, send mics and instruments from stage to a distant control desk, reducing cable clutter. - Outdoor events or long cable runs, maintain clean, noise-free audio delivery. - Conference rooms or broadcast setups where the control mixer is distant from audio sources. - Key attributes: supports 4 channels of analog XLR signals, two-unit pair, shielded balanced Ethernet connection, compatible with standard 3-pin XLR devices, suitable for indoor and outdoor use.
