I originally wrote a very positive review but it turns out this item failed in eliminating static noise in my JBL Eon speakers

Unfortunately did not clean up my RF noise, but now I know my power is clean and gear is protected

This product solved an electrical disturbance problem I was having, which was causing additional background static noise in my audio recordings

A constant almost inaudible high pitched noise that could be masked by sound, but was always present

Also, some reviews say that this has gotten rid of humming noise.

/gain staging had zero noise

Purchased one for a family member who lives in rural area where the power fluctuates and this is used to protect her electronics and clean up any signal noise from electric current actually seems to give a moderate boost to performance to equipment.

eliminated the nasty noise from my peddle board and powered PA studio speakers

Does not fully eliminate him noise but protects you’re gear!

Does kill some noise by comparison to the house plastic units most use.

Hooked up my ole Dual turntable and pioneer receiver, both 70s technology, that used to have a terrible humming noise when plugged into wall outlet, into this power conditioner, turned them on, and wow

Thought I had a faulty guitar amplifier (noise, hum)

clean-- no noise

Cute noise on my pedal board

Then, there was this horrible electrical chatter type noise that would come and go, but was most noticeable when opening my DAW or any other audio program and when I would move my mouse around

It won't fix problems on the DSL line itself, but it will deliver clean noise-free power to your DSL modem or gateway, and many times, that's all you need.
