How has anyone solved this problem cause I got the same

A number if things can be wrong with it, from the audil preamp to the the audio amplifier. Even as simple as a bad volume control. Does the actual noise change patterns when you move the volume?

This type of active speaker by Mackie has a issue with operational amplifier ic's inside, they are just those little black things with 8-pin soldered to the pcb, you may have some of them damaged, because of the erratic operation of the units, let me know if i can help more.

Sounds like you could have a blown amp/speaker or you've got a short in your speaker lead. Typically, when there's not enough resistance on a wire is when you start getting the crackling noises.

Hello
The noise is actually a product of dust from a blue ray disc.Over time these discs heat up and leave a residue on the blue ray lens.
Try using a lens cleaner to remove dirt and clean lens.
Also i read an article that using a wireless controler can also cause freezing of the blue ray.

Does it make the noises at higher gains with nothing plugged in? If not, check your guitar cables and connectors.

Are your speakers factory? Sometimes the wires start corroding from moistures or from not being covered well. If you can or know someone who can, you may try checking the wires to the speakers/radio. If they are corroding, they may be shorting out.

Hi

The problem is with the amplifier itself. Crackling is usually capacitor related and you will need to have the amp checked over to properly identify the cause.

Some amps are also prone to pick up static from other electrical items which can also cause these problems. I had a crackling issue with an old Crate amp of mine which turned out it was due to being too near a computer/monitor so it is worth eliminating these things as a possible cause before having the amp checked.

Hope this helps. Thanks for using FixYa.

in my car when I press the accelerator there is hissing sound,did check the air filter by disconnecting the plumbing but still the sound is present any idea what could be causing this sound.

Sounds like an internal loose connection somewhere, possibly anywhere, a connector on a pcb, a dry solder, loose pin on an IC. Tough for an end user to solve this, would entail opening the unit and investigating. I checked the rear panel in the op manual and this model has no ribbon connectors else i'd have asked you to check them.

A quick quess of mine is the following:

The OVERLOAD indicator lights up when the receiver is maxing out on the current it is sending to the speakers. My guess is there is possibly something wrong with the receiver itself, especially since the B speakers won't play. Either that, or something is broken in your speakers or you are using a set of speakers that have too low an impedance rating for your receiver.
