Bidirectional design supports one input to four outputs and four inputs to one output, no power supply required. 6.5mm + XLR dual interface distributor supports TRS and XLR 1x4 signal distribution with noise reduction and current shielding. Interface design features standard three-pin XLR balanced and 6.5mm jacks, enabling interference-resistant transmission through hot, cold (-), and ground connections. Input impedance matches professional audio equipment such as mixers and preamplifiers. Maintains signal balance characteristics and supports up to 50 meters of transmission without signal loss. Electrical isolation is achieved using high-quality audio-grade transformer coupling to prevent ground loop noise. Parallel output design ensures consistent signal levels across all channels. Typical applications: - Stage sound reinforcement systems: distribute main signal to multiple power amplifiers or active speakers - Conference systems: distribute intercom signals to multiple receiving terminals - Recording studios: enable simultaneous multi-track recording signal distribution Note: This device does not provide signal amplification. For long-distance transmission, use with a line amplifier. When connecting multiple devices, use proper topology to avoid signal reflection.
