## Questions & Answers

**Q: Can I connect a speaker to the headphone amplifier output?**
A: This headphone amp is for headphones only, not for direct speaker connection. It lacks power to drive passive speakers. Improper use may cause distortion or damage. A separate power amp is needed for passive speakers.

**Q: Why is there noise or buzzing when I use the headphone amplifier?**
A: This may occur with a non-original power adapter, loose cables, or nearby interference. Use shielded cables, avoid max volume, ground devices properly, and keep the amp away from microwaves, phones, tablets (e.g., iPads) and Wi-Fi routers.

**Q: Why is the sound distorted when using the headphone amplifier?**
A: This can happen if input volume is too high, amp output is too loud, headphone impedance is incompatible, or power adapter isn’t original. Try lowering input/output volume, using standard 32–100Ω headphones, and always use the included 12V adapter.

**Q: Why is there sound in only one ear when using the headphone amplifier?**
A: If you're using a stereo sound source, make sure to press the Stereo switch button on the amplifier. Otherwise, only one channel may be heard. Also check that you’re using a TRS (stereo) cable and it’s fully plugged in.

**Q: How should I connect the headphone amplifier to my devices?**
A: PC: Use rear LINE OUT/AUX/headphone jack; avoid front for better signal. Phones: 3.5mm-Type-C/Lightning adapter (some auto-pause—resume). Tip: No phone grounding—avoid touching. Important: Volume <80% to avoid distortion.
