How to troubleshoot no power on BMB Amplifier?
If your BMB Amplifier has no power, ensure that the power plug is firmly connected to the power outlet.
What to do if my BMB Amplifier switches functions unexpectedly?
If your BMB Amplifier switches to AUX, TAPE, or BGM while playing KARAOKE or DVD, and the input sensitivity of KARAOKE or DVD is low, set the SENSITIVITY switch on the rear panel to H.
How to fix no sound from microphone on BMB Amplifier?
If there is no sound from your BMB Amplifier's microphone, but music is playing, check that the microphone switch is set to ON. Also, inspect the microphone cord for any breaks and repair or replace it if necessary. Ensure the microphone plug is properly connected.
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.
Why is there no picture when playing KARAOKE or DVD on my BMB Amplifier?
If the playback picture does not appear on your BMB Amplifier, even with a KARAOKE or DVD signal input, set the AUTO SELECT switches to VIDEO or A & V.
