SOLUPEAK X103 1 in 3 Out XLR Balanced Stereo Audio Switch Selector Box

The X103 is a passive, balanced stereo XLR selector for users who need to choose among three output destinations from one input pair. A rotary control handles output selection, with no amplification, volume-control circuitry, or external power supply. The enclosure measures 120 x 100 x 60 mm and uses an aluminum housing, matching knob, and an FR4 board at the rear. Its layout omits internal wires and minimizes board traces for a straightforward signal path. Shield is assigned to pin 1, positive to pin 2, and negative to pin 3.
