Two adapters enable sending four analog XLR audio channels over a single RJ45 cable. Use to send stage lighting or audio signals to a distant mixer or lighting desk, reducing cost and cable clutter. - The device features a unique differential impedance transformation and analog spread-spectrum isolation technology with anti-interference and noise suppression capabilities. It effectively addresses device distortion and audio hum from long transmission lines or ground-loop currents, and reduces background noise and other anomalies. - Our versatile expander works with 6.5 mm and other 3-pin XLR systems, microphones or line-level sources. It provides balanced digital/analog transmission and delivers clear, crisp, high-quality sound with no residual noise in a variety of indoor and outdoor environments. - The two adapters transmit four analog XLR signals over an RJ45 network cable, linking mixer, microphone and instrument to the XLR inputs and routing all four signals over a shielded, balanced Ethernet cable to the other adapter. (RJ45 cable not included).
