Bidirectional design, supports one input and four outputs and four inputs and one output, no power supply required. 6.5+XLR dual interface distributor, supports TS+TRS XLR 1X4 distribution, with noise reduction current shielding. Interface design: Adopts standard three-pin XLR balanced + 6.5mm interface, realizes anti-interference transmission through hot end (+), cold end (-) and ground wire, and the input port impedance matches professional audio equipment (such as mixer, preamplifier). Maintain signal balance characteristics, support up to 50 meters of transmission without attenuation. Electrical isolation is achieved through audiophile-grade audio non-polar capacitor coupling to avoid ground loop noise. Parallel output design ensures consistent levels of each channel. Typical application scenarios Stage sound reinforcement system: main signal distribution to multiple power amplifiers or active speakers Conference system: intercom signal distribution to multiple receiving terminals Recording studio: signal distribution for simultaneous multi-track recording Note when using: the distributor itself does not provide signal amplification function, and it is recommended to use it with a line amplifier for long-distance transmission; when connecting multiple devices, it is recommended to use a star topology to avoid signal reflection.
