Re: Connecting a Yamaha VX7 Subwoofer on my Yamaha HTR...
You can connect the VX7 to the 5730 using an RCA Y cable like the one shown in the picture below. You get your one connection for the receiver and 2 for the VX7. These are available at any electronics store. Remember that the cable should be long enough to go from the receiver to where subwoofer will be placed. Hope this helps. Let me know.

You need a long enough subwoofer cable ( Male connectors on each end ) and connect it to the female RCA input on the sub and the rear of your receiver has an output labeled subwoofer out connect the other end of the cable there and you are good to go. Make sure both the receiver and the subwoofer are powered off when making the connections.
Depending on the model, there are two ways to connect a subwoofer to an amplifier, receiver or processor. The best way is to connect the subwoofer to the SUB OUT or LFE output of a receiver, but some subwoofers can be connected to the speaker level outputs of the receiver or amplifier.
1. How to Connect a Subwoofer to the Subwoofer Output
The preferred method of connecting a subwoofer is through the LFE or Subwoofer output (SUB OUT) of a receiver. Almost all home theater receivers (or processors) and some stereo receivers have a subwoofer output. The LFE (Low Frequency Effects) is a special output for subwoofers and is often labeled 'SUBWOOFER' not LFE. 5.1 channel programs on DVD discs have a dedicated .1 channel output with bass-only content that is best reproduced by a subwoofer. Connect the output of the LFE or Subwoofer jack to the Line In jacks of the subwoofer using a single RCA cable (the two jacks on the left in the photo). A 'Y-Cable' may be necessary to connect the LFE output to both the left and right channels of the subwoofer.
2. How to Connect a Subwoofer to Speaker Level Outputs Some receivers and amplifiers do not have an LFE or Subwoofer output. In this case you can use the speaker outputs of the receiver to connect the subwoofer. Using speaker wire, connect the left and right channel speaker outputs of the receiver to the left and right channel speaker level inputs on the subwoofer (the speaker inputs on the right side of the photo). Using speaker wire, connect the left and right channel speaker outputs on the back of the subwoofer to the left and right channel front speakers.

Just for clarity, I need to explain what the four inputs are on the KEF subwoofer. There is a left and right RCA input which is the input signal to the subwoofer and there is a left and right RCA output which is the High Pass output from the subwoofer.
On the back of the Yamaha receiver, you said you have a subwoofer output. This output is most likely the mono subwoofer part of the home theater system and can be used if you like. The left right signal input into the KEF is summed into mono so if you only connect one channel you will basically reduce the signal level by 1/2 (-3dB) but it will work fine.
Alternatively, if your Yamaha receiver has monitor out and monitor in, you can run the monitor output signals to the subwoofer and you can then run the high pass outputs from the subwoofer back to the monitor in. This will give you the subwoofer and provide a smoother signal matching with your audio system.
It is not always easy to connect the subwoofer up to an integrated receiver/home cinema system using the high pass channels of the subwoofer as you don't always have access to the analog output and input of the front channels. In this case, just use the Subwoofer output or just the monitor out only.
How is the audio connected to the TV (be specific)?
Keep in mind that a TV is not generally an audio source as its programming always comes from something higher up the audio food chain than itself. Get the audio to your receiver from whatever THAT is, not the TV.
Your subwoofer probably has both high-power inputs and "normal"low inputs. The first are for receivers, which don't have link-level output for sub, so they are able to take already amplified signal as input. You need to use link-level input of your sub and connect it to subwoofer-output of your receiver. The output is marked as OUTPUT - Subwoofer and is black-color RCA plug (don't confuse with subwoofer INPUT under MULTI CH INPUT). Receiver has only mono output for subwoofer. If your sub has stereo input (white/red RCA plugs), connect just the left channel to the receiver, it will still work. Don't connect anything to the speaker output on the sub, you don't need that.
Check your settings in the Receiver Main Menu. Go to Speaker settings, then to Subwoofer, and select "Yes" or "On" or it may say "LFE or Both" choose "Both" Hope this helps. If you still have a problem, post a comment and I can help you some more
i have the same tuner.on the back you will see all connectors bottom row of rca jacks you will see subwoffer if your sub has to rca. red/white use a splitter monstor cable gold ..works best. i use Home Theater Reserch speakers... you can also plug your subs power plug into the tuner snd you never have to power it on seprate .........
