Meridian Unplugged - Powered by MrTechGuy.co.uk Forums Discussion Meridian - Streaming DSP5200 and MC200 error

You should try to plug the MC200 in the PS audio if there is a free slot or rent/take a power strip so both speakers and the MC200 on the same level.

Another possibility is just to turn the main power plug from the AC200 when this a F-type (Hot, Neutral, Ground), that can help.

Also try that when you plug it in the PS-audio or power strip.

Doing all that is to minimize the main voltage differences on all your audio equipment (on the neutrals).

Report back your results please.
