Kef connection How to connect to amp

Based on the information provided, it seems that there may be an issue with the DVD unit of your Kef kit 120. Here are a few troubleshooting steps you can try: Check the power source: Make sure that the Kef kit 120 is properly plugged into a working power outlet. If it is, try plugging another device into the same outlet to ensure that the outlet is working properly. Check the cables: Make sure that all cables are properly connected to the Kef kit 120 and that there are no loose connections. Also, check the cables for any damage or signs of wear and tear. Reset the Kef kit 120: Try resetting the Kef kit 120 by unplugging it from the power source for a few minutes and then plugging it back in. This can sometimes help to resolve issues with electronic devices. Contact Kef customer support: If none of the above steps resolve the issue, it may be a more serious problem with the DVD unit itself. In this case, you may need to contact Kef customer support for further assistance or to arrange for a repair or replacement.

I'd suspect a shorting voice coil in the woofer or a loose connection inside that vibrates and presents a wildly varying load.

Disconnect the bi-wiring jumpers and try driving each 'half' separately as a test for tripping the amp.

If you have posts that look like this, yes - just make sure the straps (connecting the red to red, etc) are removed.

Bass is mono directional in the main,and while your sub has a left and right input ( because a few amps do have left and right sub outs) only one of them is required (usually marked as MONO on the sub). You can also get a Y splitter phono adapter and connect the single cable you have to both sockets, which is how I have mine set up. This is most common

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.

I hope this solution is helpful.

Most eq's connect throught the tape monitor jacks "in/out" and you select tape 1 or 2 when using the eq.

First of all the KEF is a powered sub which means that it wants a line level signal NOT a speaker level. Send the signal from a tape output or pre-amp output to the sub input. The overload is because the impedence load for the speaker output is too low and looks like a short to the amp. Continued attempts to connect the system as described will result in damage to the output section of the amp.

Please let me know if you need more info.

If your amp has a "sub out" jack, that's the best way to hook up this sub. You'll just need a single RCA (also called "phono") cable. Connect it to the Left input on the sub, which should also be marked as "mono"

If your amp just has speaker-level outputs, then connect the left and right main speakers from your amp to the sub's high-level inputs, and then run wires from the sub's high-level outputs to your speakers.

If you're running a surround-sound setup, use the front-left and front-right speakers for this hookup.

to test a speaker you can hook up a batterie any where from AAA AA C D or a 9 volt batterie if the speaker makes a tone then it is fine and your problem is else where

Units going into auto protect are usally due to open or dead short conditions to keep the system protected from blowing the final amps. based on what you suggested I woould test or change out the cables 1st.
