## Questions & Answers

**Q: What's the attenuation, in dB? (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
