monitors interference

When I use power supplies for stuff like the laptop or printer it causes a lot of static noise on my monitors. When I plug them in elsewhere in the house it doesn't affect them. Is there a relatively cheap unit or 4 way that I can buy that will screen the noise? I am using balanced jack to XLR cables for the monitors, I don't get noise from the system, just the mains.

Thanks in advance for help and suggestions

Where are your monitors plugged in? What kind are they? Passive? Active? Are you sharing a power strip with other devices? Do you have a dedicated circuit for your audio gear? What is supplying audio to your monitors?

Usually a hash type of noise is created from cheap switch mode power supplies. You could invest in a better regulated power supply.

If you are only experiencing the noise when you are connected into the audio circuit, then a DI with a ground lift may help.
