Hosa YMP-233 — 3.5mm TRS to Dual 1/4 in TRSF Y Cable
YMP-233 Overview
The Hosa YMP-233 is a signal-duplicating Y cable that routes a single 3.5mm TRS stereo source to two simultaneous 1/4 in TRSF outputs. It is purpose-built for headphone monitoring scenarios where a single headphone jack must feed two sets of full-size headphones. This cable is a practical solution for audio engineers, studio assistants, broadcast operators, and educators who need to share a stereo monitoring feed without additional hardware.
The YMP-233 provides a straightforward, passive adapter solution that requires no power and introduces no additional signal processing into the chain.
