Hosa GPM-179 3.5 mm TRS to 1/4 in TS (Mono)
The Hosa GPM-179 3.5 mm TRS to 1/4 in TS (Mono) adapter is a compact, reliable way to convert a stereo mini-plug into a single mono feed. It takes a 3.5 mm TRS mini stereo connection and delivers a mono signal to a 1/4" TS input, summing left and right channels so your source can drive mono gear smoothly.
What it does
This passive adapter merges stereo channels from portable devices into one mono output. No power is required, so it’s ready to go wherever your rig takes you—from the rehearsal space to the stage—without adding extra batteries or clutter.

- Plug the 3.5 mm TRS end into your stereo source (phone, tablet, laptop, or portable player).
- Insert the 1/4" TS end into your mono input (guitar amp, mixer, or other mono device).
- Play and adjust levels as needed—the left and right channels are summed evenly for a balanced mono signal.
