ARRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRGGGGG!
I finally figured out the JBL Compact Eon One issues.
NOW - I am trying to stop the hiss coming out of my RCF 12s.
Am using an RCF F 10XR mixer, with a Denon MC4000 controller.
Everything is plugged into a Furman (can't remember the model number)
Dell Laptop.
From what I am "Googling" it is a common problem with powered speakers.
Any way to solve this??????

is is a hiss - or hum ?- Try another outlet... try running the laptop on battery - I've used a Hum X in the past to deal with "noise" .

i found when I have a substantial hiss it's becuase I either accidentally have the mic levels on on the mixer (but mics off) or my gain structure is off somewhere.

If it's a hiss I would say somewhere in the gain chain. How are your gains set?

Definitely hiss.
Speaker gains are set at 12 o'clock.
I did try the mic gains. Maybe it is a matter of the levels.

Hiss is usually a gain issue. Leave your speaker gains where they are and plug them directly in to a wall and see if there is a hiss in the speaker due to a fault. If not try turning the gain up on the speaker while connected to the rest. I'm almost willing to bet raising the gain on the speakers and/or the master will lessen if not eliminate your problem

Did you check for feral cats inside the speaker? They make a loud hissing sound too.

Yes gain staging is the number one reason for hiss. Look for an unused input on the mixer or speaker (if it has more than one input) with the gain turned up really high.

Trim volume, channel volume, output master volume, mic volume gain (line or mic), which is the biggest culprit. If it's set to line, and you have it cranked to be heard, switch it mic, then adjust the gains commensurately. Conversely, if it's set to mic and the volume level is at 1 or 2 compared to the channel volumes at unity, switch it to line.
