SOURCE: Mackie SRM450 speaker keeps making a 'popping' sound
First thing is to verify that a ground loop from your driving equipment is not causing the problem. Easiest way is to drive it with a BATTERY operated little CD player so no ground loop could exist.
Verify that your power cord is in tight and try another cord to verify it is OK.
Beyond this, service is probably required. If unit is out of warranty, you could have a person open it up to see if anything is obvious.
A possible proble is bad connectors or worse, a cracked circuit board.
Analyzing if noise is from both the woofer and high range speaker is a first step.
SOURCE: Brand new, distorts intermittingly. Used same
Common causes of this are improper level setup. You MAY be overdriving the inputs. Use the pad buttons to limit the input for higher output devices. Saturating the input(s) will cause bad distortion. Observe if any of the clip indicators are coming on. If they do, then use the pad buttons. If they still come on due to very high output device, you MAY have to use an external attenuator. Every mixer has different characteristics and some can accept a wider inout range than others.
