    Mystery Solved Mystery Created

    Occasionally, I hear trucks idling near my home. Most often, it's a delivery truck, Emergency or some kind of utility maintenance. Most often, I ignore it, but a couple times last year, an "idle" seemed to go on for a long time... a peek out the window revealed nothing.. oh well.

    Then, last night, one tower of my stereo speakers (IL60s) began to idle! The speakers are powered (sub woofers have their own amps) and are plugged directly to outlet (stereo was off)) independently. Each speaker has a LED indicating "signal" (no signal, red. signal, green). Right speaker LED green.

    This persisted for about a half hour and "resolved" as it started. System is pre Wi Fi or Bluetooth so, WTF?

    Mice?
    Gremlins?
    Ghosts?
    Thoughts?

    Loose connection somewhere on that side creating a rectifier which is "tuning in" some random RF energy.

    Start by checking the speaker wires. Tighten if loose, replace if broken, corroded.

    I feel for you. I recently started hearing this really annoying tick - tick - tick, while in the kitchen. I'm the guy, so responsible for fixing stuff that's broke, finally had to ask my wife if she heard it. "Yes, it's the analog clock that you can now hear with your new hearing aids".

    Living in the middle of nowhere, I have a transformer in my yard. Normally, I don't hear it, but if the power goes down, it is eerily quiet without that 60 cycle hum. In the house it is incredible with no power. Electricity is NOT silent!

    This "hum" was far lower than 60 cycles and "wiring" was specifically laid out (fixed via plastic retainers) to mitigate spurious signals (from magnetic fields when operated at higher volumes). Aside from the componentry, the only other items on the same line are two 60 watt CFL lamps. There are no other "viable" EM sources in proximity (outside transformer is about 250 feet away).

    Essentially, aside from the occasional power outage, these speakers have remained "Live" since 2003 (again, they sleep unless a threshold line signal is detected). I've unplugged them from power and will see what happens once power is restored.

    I would also note that their regular operation seems unaffected and the idle is rare.. but worrisome (I likes me IL60s).

    More than likely, it's bat related.

    Hard "reboot" and right speaker still indicates a signal while remaining silent. My Gawd, I even referred to the USER'S MANUEL!!!!

    Each tower has it's own independent gain control (among other features) but is not easily accessible. One day, when looking for the bat, I'll reconfigure from scratch.
