Function and performance 1 input to 4 balanced outputs with isolation, delivering reliable sound distribution while preserving signal integrity and reducing ground noise across outputs. Why you need it Essential for live sound technicians and studio producers who require routing a single signal to multiple devices in critical environments. Maintains channel quality and minimizes interference in complex sound networks. Compatibility and reliability Designed for use with line amplifiers and in complex sound networks. Keeps performance consistent across multiple outputs in professional setups. Build and features metal housing for durability; standard 3pin adapter; capacitor coupling to ensure consistent channel performance across professional sound setups. Use scenarios 1) Live events: connect a line amplifier from the main mix and distribute to four outputs such as stage monitors, recording devices, and processing units. 2) Studio production: route a single input to multiple outboard gear and effect processors for parallel processing. 3) Broadcast or event installations: reliably distribute the same signal to several destinations with isolation to prevent ground noise.
