building home theater have a few ??s

post #1 of 5
Thread Starter 
First of all to explain some of my odd questions all of the wire for each speaker will be ran inside of the wall/ceiling. Aside from the speaker set up I will be running alot of other connections to make this room as clutter free as possible. My goal is to have four theater seats on the floor with no visible cords or wires.

Will be connectiong a 680 lightning to SONY STR-DH520 reciever via hdmi for sound and video those parts were already bought so please dont tell me why those are bad choices because they aren't changing.

First question is what media uses 7.1 sound??? cant decide if hooking up the 2 extra speakers will be worth it.

Second question is maybe a dumb one but I will be able to have in game 5.1 sound if its hooked up the way i mentioned right???

Third question : would I be better off buying a sound card? Im not an audiophile by any means but I only want to run these wires once. Will I be blown away by the diffrence between hdim/vidcard and tosslink/soundcard??


The only thing I have not purchased is a powered sub. Ive never ran anything but home theater in a box set ups so ive never needed one. Do I have to use the speaker inputs on the sub or can I just use the monorail cord. ??? Also when I run these cables they will be close to the powerlines for the new outlet im putting in will that present a problem or will the sheilding on the cord be enough.


ALso I have a subwoofer from a klipsch pro media 2.1 set. IS there any way to turn that into something I could use with this reciever?? If not is it worth buying a new amp for that or should I just buy a whole new sub woofer. I have no problem with working on pcbs so if any one can walk me through it I can do the work.

Oh yea also saw some in wall subwoofers any one ever used one or is that as bad of an idea as it sounds??


Like I said I already have all of the speakers but they are on the generic side and both came with home theater in a box sets. I do plan to upgrade those down the line but cant afford to do it all at once.

Budget is not really an big factor here I only ask that you keep in mind im not an audiophile so any "high end" equipment would be waisted on me. thumb.gifthumb.gif thanks

Use the HDMI to the receiver. You will get up to 7.1 uncompressed audio. With a regular soundcard through optical out, you only get 5.1 compressed. There a few home theater sound cards that have HDMI out with additional sound processing features, but it probably wouldn't benefit you.

Bluray discs have 7.1 assuming they have a 7.1 audio track. I know MKV files can support 7.1 as well.

As long as you set 5.1 to games then you should have 5.1. Not all games have surround support though.

You can use a ferrite core at the ends of the cable to prevent any unwanted RFI/EMI.

I wouldn't recommend using the Klipsch for just a dedicated sub, but if you are so inclined to do so then from the receiver you can just use an RCA or subwoofer cable from the sub out. Then a mono RCA to stereo 3.5mm adapter. You may need to use a 3.5mm coupler to connect it properly.

I would personally spend some extra cash on a sub. The Dayton Sub-1200 is about $130. It would provide more room filling bass than the Klipsch. You just need a single subwoofer cable to connect it.

thanks for the help. Looking at that dayton and it looks like a perfect fit.


but can I just not use these or will it not work that way. Sorry im pretty ignorant in the audio world.


also the klipsch does't have a 3.5mm jack it uses a 6 pin mini din for pre amp input

On a proper dedicated sub that has high level speakers inputs, yes, but in movies and gaming you won't have the proper LFE track. Essentially the channel that sounds low frequency sounds to the sub. It will just be playing from the right and left channel with the method you mentioned.
The ones on the Klipsch are just outputs. I forgot that the input is part of the right speaker.

I'm sure you could wire it, but figuring out what pin is which and what they do will be a problem.
