i'm just wondering that : is it possible to use regular rca cable for coax audio input ??
as i just tried it with my sony rcvr and the front panel does light up saying digital input. but i just need to know if it turned-off my subwoofer as now i don't get any sound from the sub.even test tone doesnt work. plz help
Unplug the digital connection and go back to anolog and see if the sub works. It did not turn off you sub, if your sub still does not work check your connections and your subs power.
