Hosa YPR-257 — Stereo Breakout 1/4 in TRS Female to Dual RCA
YPR-257 Overview
The Hosa YPR-257 is a stereo breakout adapter built to split a stereo signal from a single 1/4 in TRS female jack to dual RCA phono jacks, with black and red color coding to identify left and right channels respectively. It provides a straightforward solution for adapting stereo cables terminated with RCA phono plugs to equipment featuring a stereo 1/4 in TRS jack. This adapter is well suited for audio engineers, system integrators, and venue technicians who routinely bridge consumer and professional signal paths. Its compact form factor makes it practical for use at the patch point, rack, or stage.
The color-coded RCA jacks eliminate channel confusion during fast setup and teardown, reducing the risk of miswired stereo signals in live or installed environments.
