    My Elk M1 Gold has two M1KP2 LCD keypads and associated SP12F speakers all set up to provide voice messages when arming, disarming, etc.  For the past decade and a half there has been only a slight barely noticeable hissing (more like low white noise) in the background when these voice messages were broadcast (not problematic), yet as of a couple of weeks ago we now hear a very noticeable buzzing in the background on broadcast, in both speakers.

    I haven’t made any changes whatsoever to my system for perhaps half a year and this buzzing is noticeably the same on both speakers.

    Anyone have any ideas on what could be causing this?

    Are the speaker wires ran in close proximity to 120/220 VAC lines? Disconnect the existing speakers and connect one directly to the OUTPUT 1 and test. The system could have taken a slight surge which may have damaged the onboard amplifier.
