  If the Boss Audio Systems Recording Equipment isn't turning on, ensure the power switch is set to “USB” when using USB bus power, or to “ON” if using the AC adapter or batteries. Also, if you're using a notebook computer running on battery, connect an AC adapter to the computer. Check the power management settings of your computer and consider using a self-powered hub.

Why does my Boss Audio Systems Recording Equipment recorded sound contain noise or distortion?
- B
  Bruce WrightAug 23, 2025
  If your Boss Audio Systems Recording Equipment is producing recorded sound with noise or distortion, adjust the input sensitivity so the PEAK indicator briefly lights when the loudest passages occur. If you are using a microphone with high output impedance connected directly to the BR-800, consider using a commercially available microphone preamp before recording, as the INPUT 1–4 jacks are designed for low input impedance.
