Subwoofer Output - Please Advise
 
Hello everyone, I decided to join this forum to expand my knowledge on electronics and audio. I hope to meet lots of people and learn a few things. I currently am working on a surround sound setup and I want to ask if I have my subwoofer connected correctly, the back of the subwoofer is different and new to me.

Yamaha Receiver - RX-V463
Klipsch Quintet iii 5pc speaker set
Klipsch 10" subwoofer

The subwoofer has two connections labeled HIGH LEVEL IN and two connections labeled HIGH LEVEL OUT. There are also two RCA jacks labeled LEFT/LFE and right. Right now, I have a white RCA plugged into the subwoofer out and the other end plugged into LEFT/LFE so white on white, its just a cable, right?. Its actually an audio cable for left and right/red and wide. I just needed something to use. Will this cable work ok? Also on back of the sub it has two switches 180 degrees and 0 degrees for phase and switch for Auto/On. How should these be selected?
Thanks

You're 99% of the way there.

The "high level" in/outs are used with speaker connections (if your receiver didn't have an LFE output) and it sound's like for your application, you won't use those at all.

The RCA connection goes to your receiver just as you've reasoned but since your receiver has a left LFE and a right LFE, it's designed for two subwoofers. Since you only have one, check to see if there is a receiver menu which selects something like "single woofer use". It's quite possible that the receiver sends identical audio to both LFE outputs, in which case you're fine as is.

As you surmised, any decent audio cable will work for the sub line. You only need a single line though you can use a red/white cable and just use one side (like you described). Check with Monoprice if you want a single line cable.

The phasing switch (0 or 180 degrees) should be set so your subwoofer reinforces low frequencies. Just play something with really low frequencies and switch it back and forth. Leave it at the setting which give the loudest room fill for the lows. If your main receiver is directing low frequencies to just your sub, the switch position won't make much difference. In that case leave it at 0 degrees.

component video cables are great for subs.

i also have a older yamaha, believe its a RX-V620, has a sub out on the back. youll have to go into your setting menu and look at the speaker list. helps if you have the owners manual, which you can download form yamaha. once its set up youll love it, i do. im using a yamaha sub, 150 watt, and its assume. shakes the place. it did take me a few tries to get the settings on my yamaha setting right but then what a difference.
