Why is there no sound coming from my Roland Mobile BA?
If you're experiencing no sound or insufficient volume with your Roland Amplifier, first, double-check all connections to ensure they are correct. Then, make sure the [VOLUME] knob is set appropriately. Also, if headphones are connected, the sound will not be produced from the unit’s speakers.
How to fix a Roland Mobile BA Amplifier that won't turn on?
If your Roland Amplifier power won’t turn on, the batteries might be exhausted, so install fresh batteries. Also, ensure the specified AC adapter (PSB-series; sold separately) is correctly connected. Never use any AC adapter other than the specified model.
Why is my Roland Mobile BA Amplifier sound distorted?
If the sound from your Roland Amplifier is distorted or noisy, start by turning each [VOLUME] knob toward the left to adjust the volume appropriately. Also, lower the volume of the connected device to ensure the input level is appropriate. If the batteries are low, this can also cause distortion or cut off the sound at high volumes. Replace the batteries or use the AC adapter (sold separately).
