Hosa GPP-419 — 1/4 in TS to 1/4 in TRS Mono-to-Stereo Adapter
GPP-419 Overview
The Hosa GPP-419 is a compact signal adapter designed to interface a 1/4 in TS mono phone plug with a 1/4 in TRS stereo phone input, distributing the mono signal equally to both left and right channels. This makes it a practical solution for routing mono sources into stereo inputs without signal loss or channel imbalance. It is well suited for audio engineers, system integrators, and technicians who regularly work with mixed connector environments on stage, in the studio, or in installed sound applications.
The GPP-419 provides a straightforward, passive conversion in a compact form factor, eliminating the need for additional cabling or adapters in common mono-to-stereo patching scenarios.
