One input and four outputs, four inputs and one output, two-way design without power supply Application of devices: suitable for placement between balanced devices with card interfaces. Interface design: using standard three-pin XLR balanced interface, anti-interference transmission is achieved through hot end (+), cold end (-) and ground wire, and the input port impedance matches professional audio equipment (such as mixer, preamplifier). 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. Technical advantages: maintain signal balance characteristics, support up to 50 meters of transmission without attenuation, achieve electrical isolation through audiophile-grade audio non- capacitor coupling, avoid ground loop noise, and parallel output design ensures consistent level of each channel. Note when using: The distributor itself does not provide signal amplification function. It is recommended to use it with a line amplifier for long-distance transmission. When connecting multiple devices, it is recommended to use topology to avoid signal reflection. Color: Black Material: plastic Package Contents: 1 x splitter Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
