PRO 3SP is a passive one-input and three-output isolated signal splitter without the need to install batteries or provide phantom power.

PRO 3SP has a pair of built-in UNiKA-PROTM EI9AE3R3 1.25:1 isolation transformers, which has a special copper foil layer and a dedicated ground layer, which allows this device to restore high signal/noise ratio and dynamic sound, and can avoid unnecessary Leakage caused by radio frequency interference, ground interference and potential difference. PRO 3SP is particularly suitable for recording studios, live performances and fixed installation projects.

PRO 3SP’s input uses XLR balanced sockets, suitable for inputting LINE signals. The XLR balanced sockets output by MONITOR are parallel and straight through without isolation transformers; CH-1/CH-2 output channels each have independent UNiKA-PRO isolation transformer and shared GND/LIFT switch for easy connection to remote or different power sources at the end of the equipment to eliminate the leakage and noise caused by the potential difference and the ground loop.
