HELP!! 1st time Home Theater DIY'er

[Swobe33]

OK, I'm a first time Home Theater owner looking for some help and advice. Here's the equipment that I have.

Yamaha RX-V663 7.1 Receiver
SUB-10 Klipsch 10' subwoofer
Monster Ultra 600 Subwoofer Cable

I have tried to hook my subwoofer up every which way i can think of and using the diagrams in the instructions with still no luck. I am able to get the speakers to work using traditional speaker wire, but no subwoofer output using the subwoofer cable. I have noticed on the cable there is an arrow on one end of the cable pointing out towards the one end. On the receiver there is Pre-Out section with Subwoofer '1' and '2'. The instructions tell me that its the same output on either channel there and those are the ones i should be using. The sub woofer on the back has one input named 'LFE/Left input' and a simple right side input. I'm also confused on why i only need one SW cable when there are two inputs on the SW.

So I hope I've typed enough down w/o rambling on too much. Is there a special setting that I need to use that I don't know about? If anyone has any insight, I'm all ears. Thanks so much in advance!!

Connect ONE RCA cable to your sub and you will be fine!

You only need on cable to the sub woofer. Use an RCA cable and connect to either Subwoofer '1' or '2' ( doesn't matter you receiver has connections for two subwoofers) and connect to the LFE (Low Frequency Effects --ten dollar name for "sub" ). Since the sub output is not split between right and left you only need one connection.

I think the reason for the two inputs left/right on the sub is that in some cases ( but not very many) you would provide full range to front speakers, then crossover circuitry in the front speakers would split off the lower frequencies ( "LFE" or "SUB" ) and then from the front speakers you would connect to the sub, voilla Left and right speakers left and right sub inputs. A similar and more common setup is to feed the left and right front speaker signals into a sub and then from the sub connect to the front speakers ( I had a Klipsch that had this). Just remember typically subs are powered so the signal going to them is pre-processor while the signal going to speakers is amplified.

Bottom Line - connect ONE RCA cable to your sub and you will be fine!

Good luck!

Also you will probably have to go through the reciever's setup menu and make sure you turn on all the speakers and the sub.
Read through the manual for details on how to do this.

Is an RCA cable the same as a subwoofer cable? Also when I'm trying to connect my old school super nintendo to the receiver I get sound but no picture and i have the video conversion feature on. I have HDMI 1.3B Cat. 2 120hz cables from Mediabridge that runs from 'HDMI Out" to my TV. They were $10 on Amazon. Is there such thing as too new of cables or am I getting what I paid for? Because I think they are preventing my cable box from functioning properly also. This has been a real head scratcher. Or did I get stuck w/ a lemon receiver?

Yes a subwoofer cable follows the RCA plug standard. So any RCA plug type cable could be used. Including an old component cable, an old digital coaxial cables(what I use) or some old stereo cables.

90 percent of error and maybe 99 percent are due to user error. That's why my company has a support team. To keep people from bothering me with user errors.

Make sure you read and follow the manual for your receiver and all your products. Doing so will save your bacon and your time. The difference between an engineer and idiot is an engineer has learned to follow instructions. An idiot doesn't. In other words follow the instructions. If the manual sucks then call support and ask for help. It is there job to help you and if the company gets enough calls they may learn to write better manuals. At some point you will gain intuition for fixing things, but that takes time and experience. So until then and even then follow instructions.

Connect your sub cable to the "sub 1" out of your receiver and the "LFE/left in" of your receiver. In your speaker setup on your receiver set your speakers to "small" to get the most sub output - that will tell your receiver to send the low frequencies to your sub. Also make sure in the setup that subwoofer is set to "yes". If that doesn't work - try a different cable. That Monster sub cable you have is just an overpriced RCA coaxial cable.

I don't know what the arrow is for - as coaxial cables are not directional to the best of my knowledge... maybe Monster has come up with a "revolutionary development" in coaxial cable construction...
