Meridian Unplugged - Powered by MrTechGuy.co.uk Forums Discussion Meridian - Systems Crackling from all DSPs with 861v4

All that suggestions you can/should try:

Delete all your types and then try to retype the unit to another type.
Do not copy anything start from cratch.
Setup a simple 2 Stereo layout.
Disconnect the surround speakers.
Does the crackling change with volume ?
Does the surround channels also crackling when you have "stereo" or "direct" preset ?
Have you swapped the position of cards before the crackling appears ?
Try fetch from the 861 and see if all data are correct.
List up the cards what you have and the position.

Good luck
