Hi, Im trying to turn on my home theatre but the subwoofer its on for a couple of seconds and it turn off automaticaly, the display it's on but the subwoofer its not. Coud you please tell me what to do.. Thanks. My address [email protected]
Your cooling fan is not engaging and coming on like its suppose to. One, the fan is probably burned out, which sucks because its low voltage and the only thing on the board that is low voltage. Two, there is a thermostat type component that tells the fan to start which HAS burned out and doesnt start the fan accordingly. If you look at the back fan and turn everything on you will see the fan either doesnt start or starts right as the relay trips turning the sound components off. If it starts at all your fans good.The thermostat component will need to be replace and I cant recommend a source. Just trying to explain the problem so you can look for the right repair. Hope it helps. I have one of these and have found this is the problem, but cant find the solution.

Well if it buzzes only for a couple minutes after turn on then it could be when the woofer starts pumping it produces pressure in the cabinet which creates a bonding motion that then closes the cracks, kinda like glue. Like blowing a balloon up in a box. The balloon is the pressure, OR Yes it could be your woofer is going bad. All speakers have voice coils. Tiny wire wrapped around a thin layer of cardboard then attached to the cone. This cone could be getting loose. But when the woofer heats up after a couple minutes it probably bonds the tiny wires so then the vibration or buzzing disappears. Over time woofers can die especially if it produces a lot of distortion, In a speakers life distortion kills and it doesn't matter how much power it can handle or how much money you spent on it.
Not all sub-woofers are alike. Some can handle the really low lows, and some can not. Check your settings too. Over time the vibration of the woofer will start to undo the glue, nails, screws, and even burn through the tiny wires in the voice coil. Oh and make your china crawl across the table... Have you been watching a lot more action movies? Some of the older woofers can't handle the newer digital deep bass frequencies... You may have to reconfigure your setup.
Hi, Yes you should make adjustments.KEF makes very good products, however if you don't handle this you will have to replace or service it. 1 If the woofer is very close to you, relocate it further away. The reason being is that the lower the frequency the larger the wave form. The lowest waveforms will become louder. 2 Adjust the high frequency cut off to be at 80Hz. This should eliminate boom. Higher Sub frequency tend to muddy the sound. 3 The sub should have a subtle effect in music. So the relationship between it and the speakers it augments the sound of should be seamless. 4 If you are playing Rap or Reggie music and you like to play it loud. Add another sub into the system and locate it NEXT TO the KEF Sub. In this fashion the two subs will reinforce each other's energy. They will "couple" thus multiplying their energy considerably. Hope this helps, Best Regards, Mark
If the system uses a remote control, you may need to adjust the subwoofer out signal setting or turn on the sub in a menu, and on many systems, you can only access those settings via a remote control (you should check the onkyo user manual on how to do it).
Now, this is just one suggestion, it may work, but then again, it may not.
These could also be connection problems or some internal trouble in the onkyo sub signal output section or in the subwoofer input section, but hopefuly, it's just a "turn on" or "signal level" setting in a menu.
If you have a "subwoofer-out" jack on the back of the receiver, you can put a y-cord on it and connect it to two powered subwoofers. Don't expect a big difference in the sound, however. You may even get less bass depending on where you position the sub-woofers.
"Sub-woofer output not working" problem, and notify you when a new solution is offered. Press the setup key on the front of the receiver Select the subw setting Move the multicontrol knob until the sub woofer is on Turn off the receiver and turn back on- the subwoofer should be on The operator manual can be downloaded on the web site--- free http://www.retrevo.com/support/Kenwood-VR-507-Receivers-manual/id/480ag219/t/2/
This means that you have purchased a three piece home theatre system. Two tweeters and a sub-woofer. Assuming you are using a Stereo player (Tape/CD/DVC)you have to connect the Left Output of the Stereo placer to the Left Input at the back of the Sub-Woofer and the Right output to the Right input of the subwoofer by cables. Then take tweeters and connect them to Right speaker and Left speaker output at the back of the sub-woofer ( note if the speakers are marked L/R, then connect them to the subwoofer output accordingly. In case you are using a 5.1 player, then only connect the front right and front left to the Right and Left input at the back of the subwoofer. You are and you can now start playing your music or movies and and you will get theatre quality sound.
