(Must we ask?)** A: I don't know the stats, but it goes from full volume down to zero. **Q: Two speakers -- only one stereo out. How would this work?** A: By definition, one stereo out would accommodate two speakers out. However, if your issue is you have a stereo line into this controller, but to two plugs for the out, then maybe you need some adapter to combine the two speaker inputs into one such as this: https://www.amazon.com/GELRHONR-6-35mm-Splitter-Gelrhonr-Adapter-5PCS/dp/B095PFC753/ref=sr_1_19 **Q: Since this works for headphones is it stereo inputs & outputs on this controller?** A: Yes. The input and output are both stereo 1/8" mini jacks. **Q: WIll it boost a weak signal?** A: Unfortunately no. This is a passive, in-line device. It can only make an audio signal quieter ## Frequently Bought Together - 3.5 mm Audio Volume Controller, line Volume Control Box, 1/8" aux mini Inline attenuator knob -MC11 - Nanxudyj AUX Cord 6ft/1.8M,3.5mm Stereo Audio Cable 90 Degree 3.5mm Male to Male Stereo Aux Cable Right Angle TRS Cable Compatible for car, Headphone,Tablets, Speakers - Kework 15cm 1/8" 3.5mm TRS Jack Audio Flat Cable, 2 Pack, Straight Male to Straight Male 3.5mm 3 Pole Stereo Plug Headphone Headset AUX Cord --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.at/products/304432339-3-5-mm-audio-volume-controller-line-volume-control-box](https://www.desertcart.at/products/304432339-3-5-mm-audio-volume-controller-line-volume-control-box) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-07-10*
