## Questions & Answers

**Q: The volume is very low when connecting the turntable to the MC331. Do I need a turntable preamp?**
A: If your turntable does not have a built-in preamp, you will need to add a separate phono preamp (such as the BOX series). If your turntable has a built-in preamp, make sure it's set to LINE mode to output the signal properly.

**Q: Q: What is the purpose of the pre-out port on the MC331?**
A: The MC331 has a pre-out port that can be connected to a powered subwoofer, speaker, or another amplifier with passive speakers for better sound quality.

**Q: Can headphones and passive speakers play simultaneously?**
A: The MC331 defaults to headphone output priority. To use speaker output, you need to disconnect the headphones first.

**Q: What tube models are compatible for replacement?**
A: The following tube models are compatible: EF95, 6AK5, 6AK5W, 403A/403B, 6J1, 6J1P, 6J2, 6J3, 6J4, 6J5, among others. You can test and choose based on your personal preference.
