Bidirectional design supports one input and four outputs, or four inputs and one output; no power supply required. Features 6.5mm TRS and XLR dual interface distribution, supporting balanced 1x4 signal splitting with noise reduction and current shielding. Interface design uses standard three-pin XLR balanced and 6.5mm TRS connectors, enabling interference-resistant transmission via hot, cold (-), and ground wiring. 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 through high-quality audio-grade transformer coupling to prevent ground loop noise. Parallel output design ensures consistent signal levels across all channels. Typical applications: - Live sound reinforcement systems: distribute main signal to multiple power amplifiers or active speakers - Conference systems: distribute intercom signal to multiple receiving devices - Recording studios: enable simultaneous multi-track recording from a single source Note: This device does not amplify signals. For long-distance transmission, use with a line amplifier. When connecting multiple devices, use proper topology to minimize signal reflection.
