Bidirectional design supports one input and four outputs, or four inputs and one output; no external power supply required. 6.5mm TRS + XLR dual-interface audio distributor; supports 1×4 balanced distribution with noise-reduction shielding. Interface design: Features standard 3-pin XLR balanced and 6.5mm TRS connectors; enables interference-resistant transmission via hot, cold (–), and ground connections; input impedance matches professional audio equipment (e.g., mixers, preamplifiers). Preserves signal balance; supports up to 50 meters of transmission without signal loss. Electrical isolation achieved via high-fidelity, capacitor-free audio coupling to eliminate ground loop noise. Parallel output design ensures consistent signal level across all outputs. Typical applications: - Stage sound reinforcement: distributing main signal to multiple power amplifiers or active speakers - Conference systems: distributing intercom signals to multiple receivers - Recording studios: distributing signals for simultaneous multi-track recording Note: This unit does not amplify signals. For long-distance transmission, use with a line amplifier. When connecting multiple devices, follow proper cabling topology to prevent signal reflection. Color: Black Material: Aluminum alloy Package includes: 1 × XLR Balanced Audio Splitter Note: Color may vary slightly due to lighting and screen settings. Measurement tolerance: ±1–3 cm.
