I'm hoping I'm in the right forum... if not, please tell me where to go.
We just moved into a home, and already have 2 giant headaches related to the home theater.
If you're going to tell me to run new wires, then just don't bother.. It's NOT happening, I don't have the money to destroy everything.
The walls are filled with Polyurethane Foam Insulation, and the labor is through the roof (lowest quote I've found for running the HDMI again over 60-70ft is just shy of $3k).
Again. NOT GOING TO HAPPEN!
1) The HDMI cable tip is broken... I'm in the process of splicing that, with fingers crossed.... This isn't what this thread is about (duh, we're in AUDIO), but geez what a headache that has been so far.
2) The real issue I'm here... My Receiver (Onkyo TX-SR605) came with a powered sub (Onkyo SKW-705), which has a preamp out for the LFE sub. Ok. Great.
EXCEPT! The house was pre-wired with standard speaker wire, even for the subs (the idiot ran 2 speaker wires to the EXACT SAME SPOT for "7.2", IN THE REAR.. so irritated, but that's another issue for another day)!
I've looked and looked, and I might be just slightly
over my head in understanding what's required to make this work. From what little I understand, I need to use a few resistors in series to reduce the output and reduce hum. But that doesn't make 100% sense to me.... Simply lowering the input, effectively the amperes, seems like a good start, but it needs to be clean input still, right? We're talking low/high pass filtering to an LFE, seems like it's as close to digital over analog as you can get... Again, unless I'm completely misunderstanding it.
I already tried taking an RCA cable and splicing it to the speaker wire... I simply used the outer wires as one channel, and the inner sheathed wires as the other channel (assuming it kinda works like stereo).
Without the other end hooked up to anything (so literally just plugged into the sub and that's it), the sub hums like crazy... Obviously not right.
Maybe I don't know what an LFE cable looks like inside, but outside it looks like a standard RCA (the one that came with the speaker does anyway, and I'm not ready to cut it open to see what's under the sheathing).
But I'm pretty sure they're basically the same...
Is there a device I can get to go from LFE to Speaker? or is my only option to get a new setup (a new receiver/sub combo, which obviously I don't want to do).
I've seen "Line out converters," but they're always assuming stereo. Could I still use one of these, and just use a single channel?
I really want to make use of the prewired 7.1 cabling, and have my full 7.1 system back (our old house we were able to run cabling for a proper setup, and LOVED it).
HALP! I'm confused, poor, irritated, and I want my theater system back up and running!
Thanks in advance guys!
After researching new receivers on Amazon, Newegg, etc... It looks like everything is now LFE or stereo RCA... neither which will work with my setup... ****!
