Hosa GRF-398 — Dual RCA to RCA Mono Distribution Adapter
GRF-398 Overview
The Hosa GRF-398 is a compact signal adapter designed to connect a stereo RCA cable to a single phono output. Its primary function is mono-to-stereo distribution, applying a mono signal equally to both the left and right channels of a stereo RCA pair. This makes it a practical solution for routing mono sources into stereo inputs without signal imbalance. Audio engineers, system integrators, and installers working with phono-terminated cabling will find this adapter useful for quick, reliable signal routing in fixed installations and live environments.
The GRF-398 eliminates the need for custom wiring or additional hardware when bridging mono outputs to stereo RCA inputs, streamlining signal chain setup and reducing cable clutter.
