The volume is very low when connecting the turntable to the MC331. Do I need a turntable preamp?

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: What is the purpose of the pre-out port on the MC331?

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.

Can headphones and passive speakers play simultaneously?

The MC331 defaults to headphone output priority. To use speaker output, you need to disconnect the headphones first.

What tube models are compatible for replacement?

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.
