Sony STR-DH510 Multi-channel AV receiver connected to cambridge soundworks ensemble IV w/ passive subwoofer: no sound from center channel during viewing, or during speaker level test- all other speakers emit tone, but center is dead. I have optical digital cable and hdmi connected to Sony. Also using Sony Bravia 52" lcd. Tried new speaker wire, and connecting center speaker to different channel, where it worked- not a speaker problem. Not sure where to go from here...

Might be a little fuse on the inside on the main board

Just a suggestion - does the orange light mean a short circuit somewhere?

Sorry but it's not clear enough what kind of subwoofer (passive or active) you want to use. The passive one has no power supply connection, the active one has a power supply connector and the audio connector can be connected at the "audio out" for the subwoofer, at the rear panel of your STR-DE1075. Take a look at this photo:

No. Like most AVR's it only provides a Line Level output for an externally powered subwoofer. Get a separate amp for the sub.

Subwoofer outputs on a Sony requre powered speakers.

Yes, it only supports an Active Subwoofer. That's what the Sub Pre-Out is for.

Your sub will take that input, possibly split to two RCA connectors, and its internal amplifier will do the rest. Its own manual will give the specifics.

There should be an adjustment in setup that for 2 channel sources, you may have to enable the subwoofer output. Or alternatively, if the subwoofer output for 2 channel sources is in fact enabled, then increase the crossover frequency for the sub.

sometimes these subwoofers are for builtin amplified subwoofers..so if this is the case it will not work
