DANGERDAN Posted August 28, 2012 Share Posted August 28, 2012 Had it with me at our old house when we had ceiling speakers installed, they never used this but left it in the equipment room partially wired. Iv since then had it and thought it was a noise filter which was intended because of the long line runs in the ceiling and the power cables up there which may have caused interference. Looks custom made too. Quote Link to comment Share on other sites More sharing options...
