Mackie 1402-VLZ Pro Problems/Static/Popping

[richardzulu]

I've owned my Mackie 1402-VLZ Pro for about 5 or 6 years now and absolutely love it.

But starting a few years ago, it stopped working quite as good. For some reason I get lots of static or popping in both my studio monitors and my headphones. In order to somewhat fix the problem, I need to turn the volume way up. But once the volume goes down, one or both of the monitors will cut out or have static/popping.

The monitors are plugged into the "control room" jacks and the headphones are plugged into the "headphone" jack on the mixing board.

I have the "main outs" from the mixing board running straight into my computer's sound card (and I have the outputs of my soundcard coming back into a stereo input on the mixing board). When I record on the computer, I don't hear any of the static, but I do hear it thru the monitors and the headphones while recording.

I'm assuming this is a problem in the actual mixing board. Is it common? Does it need to be cleaned?

I saw somebody post a cleaning product called DeoxIT. Is this something that might fix my problem?

Also, the 1/4 inch inputs on the first 6 channels don't work anymore. They used to work. Now I have to use the XLR inputs only. Does anybody know why they wouldn't work at all now? They actually work if I pull the cable half-way out and get it just right. I feel like there's a metal prong that used to be there that seems like it's now bent in (in each input).

Thank you for reading this.

The scratchiness on the phones and speakers plugged through the CR out jacks is from the fader. I tried contact cleaner on mine and it didn't seem to help. Seems the fix is to replace the fader entirely.

As long as you have it in the shop for the fader you might as well have them take a look at the jacks and see if they can be put bacvk into better shape.
