The unit itself is generating too much
Check that: You are using BALANCED interconnection lines (TRS or XLR) everywhere. Low quality cables can cause or let in noise and hiss.
Check that ALL, and I mean ALL interconnected equipment is powered from the SAME receptacle or power conditioner.
Check that you are not using a noisy source or recording system like the internal audio of a PC for instance.
Short the inputs to ground and see if the output noise goes away. Some effects are noisy because the inut signal after effects gets added back into the output.
You haven't described your setup and without that information there is not much more I can add. Ferreting out noise is one of my specialties. In general your input level should NOT be too small as this leads to less signal to noise ratio due to digitizing noise. Look at the Lexicon specs to find what the levels should be. Without the description of your setup I can add no more...

Hi, I'm not sure of
DO NOT use universal adapters to run these devices. Accidents are too easy and often the universal devices do no have adequate filtering. You are off on the wrong foot to start with as this unit does NOT have a polarity since it REQUIRES an AC adpter, not a DC one. What you have WILL NOT WORK. If you have connected it, it should NOT have caused damage, you just won't get any audio out, even if the unit lights up on one polarity. The unit generates both polarities inside using the AC input.

Baldwin pianovelle ps2500 my piano turns on but speakers don't sound can someone give a hint to solve this problem
So I got a used one of these for free because it had the same issue.
I read about battery failure, so I opened up the piano and sure enough the battery had corroded. I also read that the battery is only necessary for the memory feature, which I don’t care too much about. I pulled out the board (super easy to do, no screws or anything, it just pops out) and took it a local electronics/tv repair guy. In about a half hour he took off the battery, fixed a bad trace on the board with a quick solder, and handed it back. $40.
Plugged it back in, bam works like a charm.
As long as there wasn’t too much damage from corrosion, a repair guy should easily be able to do what I described.
I hope this solves your (and anyone else’s) problem!
