Hosa SLW-333 Audio Switcher — 1/4 in TRS to 3 x 1/4 in TRS
SLW-333 Overview
The Hosa SLW-333 is a passive stereo audio switcher designed to provide three signal routing options without the need to physically rewire equipment between sessions. Operating in either 1-In/3-Out or 3-In/1-Out configurations, it is well suited for studio environments where engineers need to compare a mix across multiple sets of powered monitors or switch between multiple stereo sources feeding a single pair of monitors. The noiseless switch enables quick, clean comparisons without signal artifacts or interruption. This unit is intended for line-level signals only and should not be used between power amplifiers and speakers.
Built into a steel enclosure for rugged durability, the SLW-333 is a straightforward, passive solution for studios, project rooms, and any workspace requiring flexible stereo signal routing at the desktop level.
