I have a 34 day old REL HT/1003 subwoofer that I’ve been using regularly. I connect to my preamp via line level, both left and right channels. Everything has worked great. Yesterday, when in power “auto” mode, the standby red light turns to white like normal when music is being played, but no sounds comes out of the sub. The cones don’t move, nothing. Doesn’t matter what the phase is set to. I’ve let the sub sit for hours, both unplugged and plugged, hoping it would reset, to no avail.
I double checked the rca preamp output to make sure it’s working property by connecting it to my power amp’s rca inputs, and sound flows normally (the REL was disconnected to do this). So its not an issue with the preamp. The REL seems to be receiving the signal because the light turns white.
Any trouble shooting ideas would be appreciated. REL is closed today.
