MC331 Tube Integrated Amplifier with DAC, 2 Channel Home Audio Stereo Power Amp for HiFi Bookshelf Speakers/3.5mm Headphones, Vintage VU Meter Preamp with Bluetooth and USB/Opt/Coax/RCA

Q: 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: 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.

Q: 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.

Q: 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.
