  If your Alesis Speakers are producing no sound, there are several potential causes: * **Speaker disconnected:** Ensure that the input cable connections are secure. * **Input level down:** Check the input control on the back panel and increase the level. * **AC power not on:** Verify that the blue LED on the front of the speaker is illuminated. Check the power switch and the power input cable.

Why is the output distorted on my Alesis M1 Active Mk2?
- F
  Frank NicholsAug 2, 2025
  Distorted output from your Alesis Speakers can be due to a couple of reasons: * **Power amp overloading speakers:** Reduce the level to prevent overloading. * **Damaged speaker components:** To check this, swap the channels to see if the problem is with the speaker itself. If the distortion follows the speaker after swapping channels, it may indicate damaged components.

Why do my Alesis Speakers have unfocused sound, bass frequencies muddy or missing?

  Unfocused sound and muddy or missing bass frequencies in your Alesis Speakers can be caused by: * **Inputs out of phase:** Verify the + and - connections from the mixer to the input, ensuring that 'pin 2 is hot'. * **Subwoofer being used improperly:** When using a subwoofer, install port plugs. * **Poor mix:** Compare your mix to a commercial CD of a similar style. It may be time to remix your track.
