What does it mean if my BMB Amplifier stops with an error?
If your BMB Amplifier shows an error code on the LCD and stops, consult the information below regarding power amplifier errors. If "ERROR 01" is indicated on LCD, the power amplifier of SYSTEM-1 is in error. If "ERROR 02" is indicated on LCD, the power amplifier of SYSTEM-2 is in error. If "ERROR 12" is indicated on LCD, the power amplifier of SYSTEM-1 and -2 is in error.
What to do if no audio plays on BMB Amplifier with KARAOKE or DVD input?
If no audio is played back on your BMB Amplifier, even with a KARAOKE or DVD audio signal input, check the AUTO SELECT switches and set them to AUDIO or A & V.
Why is there no microphone sound on my BMB Amplifier when set to BGM?
If your BMB Amplifier has no sound from the microphone only when the function is set to BGM, it might be because the MIC FREE switch is set to OFF. If it is set to OFF, no sound is output from microphones 1/2/A/B when the function is set to BGM.
