There is a very simple way to find out if it works on your system or not if you have a subwoofer with auto on and off sensor (I believe every sub does). If sub doesn’t get a signal for a few minutes, it goes into “off” mode with indicator light turning red (at least mine does). Once it senses an incoming signal, it automatically turns itself on with that indicator light turning green. Try this: mute or disconnect all channels except for center and LFE (subwoofer) channel. Make sure the subwoofer’s auto on and off indicator light is visible to you then run the test. Play music, DVD, frequency sweep or whatever that has some mid range and bass in it. Let me know how it turns out.
