Narrowed issue down to subwoofer after trying multiple cables to connect AV receiver to subwoofer and changing a few settings on the AV receiver itself. Before I go inside and see if anything is clearly damaged are there any other good troubleshooting tips, and is there anything I should be aware of before opening the subwoofer up?
Subwoofer model is an Infinity SUB750 connected to a Pioneer Elite EX-500 AV receiver (silver one, not the black one). EDIT: Do I have the multimeter on the right setting? And how do I plug the multimeter in properly with these pointy ends?
Hi @tronke , Have you proved that there is output from the receiver to the sub woofer? Try connecting a DMM (digital multimeter) set to 20V AC scale to the receiver’s SW output and check for a reading when playing audio which would use the SW It most probably will be less than 20V but just selected that as a safe starting point. You could also try low frequency response headphones and check if you hear it at the receiver as well, but the meter is more conclusive if you’re not sure about the headphones’ response to low frequencies. Just a thought.
