All of a sudden i'm getting a loud popping from from 1 monitor channel when I
turn my Firebox's volume knob down. My signal chain has not changed. Any Ideas. Clean signal all other times.
 
Is it *while* you're turning it down or *once* it's turned down? If it's during, try some tuner cleaner spray on your volume control.

If that doens't work, flip the monitor cables around L-R and see if the popping moves with the cables or stays with the monitors.

Thanks SSG - yea it's during the the knob being turned down. I don't think it's the volume pot itself, (pretty new gear) and it's one volume knob for both channels. The popping is only on one channel. I will try the cable swab when I get home (heavy duty Hosa gold 1/4" trs connectors - 6 months old).

I have concerns toward the active biamped monitors during troubleshooting. Is there much risk of damage to the speakers, crossovers or otherwise?

Also I will clean the pot, thanks again.

Well, if the popping is severe and the volume is loud enough, there's always a danger of damaging the speaker elements themselves. Using active monitors - presumably with amps well-matched to the drivers and probably with at least some overload protection - the danger is probably lessened, but I'd still be careful about not cranking them too loud until the popping goes away.

When you clean the pot, exercise it fairly rigorously wile the power is turned off to everything. By that I mean simply turn it back and forth completely from bottom to top a good several dozen times or more, just to help clean the contact path completly should it indeed be some form of dirt or corrosion in the pot.

Hosa=SHIT cables :mad:
 
Event replaced my monitors, great company!

I replaced the Hosa cables with Monster, trs to xlr.

The culprit is the volume pot on the Firebox. I've cleaned it but it still wants to zap my monitors with really scary electro static pops when I'm turning the volume down. The FB has been treated with kid gloves from the get go and is 1 month past warranty coverage. Presonus unlike Event are robotic jerks in my view. For $75 and 3 weeks they will remedy. But hey business is business.
A good dose of my disenchantment is based more so on their attitude then the still warm warranty experation time frame.

So now to the point: I'm using another set of line outs from the FB to my monitors which signal wise is no problem but there is no additional volume pot for such. How can I control the monitor volume with hardware? Buying a mixer, Mackie Big Knob or Presonus Central Station (as Presonus implyed I should consider) would be overkill function and budget wise. The various software volume controls via my daw and xp are a pretty wild & wooly ride as I navigate different audio offerings through my computer (my daw mixes, itunes library, on-line tuneage via windows media player and so on)

Prior to this FB volume pot crapping out after 13 months, life was good. Btw... My Firebox has been safetly packed away in it's original box for 9 of the 13 months due to my move and new music room getting set up, which kinda makes the whole Presonus thing a little tougher pill to swallow. Thanks for any ideas and your time reading through all this drama.
 
yo i just got event and firebox a week ago i notice that too......but didnt think much of it.......its only when i turn it off and the speaker dont have to be hooked up to the firbox.......should worry thought that could be normal..?? b
