I have a Kenwood VR-507 and a Kenwood SW-35HT subwoofer connected to it. When I first started connecting all the cables on my first home theatre system, the subwoofer was working. Well, during the course of my "experiments", I noticed that the SW-35HT wasn't producing any sound at all. I don't know if the subwoofer has failed or the VR-507 subwoofer output has failed. So if anybody can tell me what steps to remedy the situation, I'd really appreciate it. Thank you.
"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/

The receiver's out put sections are grouped in pairs. Front left and right in one output, rear left and right in second output, and center channel and sub output on the third. Sounds like a semiconductor or semiconductors have gone bad in the center & sub output.
Short circuit protection energizes. Check for any external short circuit with connecting sires to sub woofer. If it found OK, the sub-woofer output amplifier section circuit inside the set is fault. Short circuited component/s. Check and replace them. Contact any service technician. If you wish to get some details; check the site linked here.

It sounds like the problem is not with your VR-606. If you hear a hum from the sub, the problem is more likely to be in the sub's built-in power amplifier. However, it is worth resetting the amplifier to factory presets. To do this, unplug the power cable from the mains supply and reconnect whilst holding down the power on/standby key. If the hum persists, connect any powered speaker to the sub-out socket, power on and listen for the hum. If no hum then suspect the powered sub amp. Turn the sub on with no connection to the Kenwood VR-606. If hum persists, the sub has a problem and will need to be replaced or repaired. By the way, you said there is a low frequency hum through the 'speakers' for about 30 mins. Is that all speakers or just the sub? Hope this helps.
I suppose you could, but you are talking about a driver (speaker) that was not designed for that cabinet size and amplifier used in the Kenwood, There are differences in speaker design besides power rating and impedance.
You can download the manual from Kenwoods site.
While the unit is in Standby mode, press the B.Boost button for a second or two. You should now be in the Menu. Select SWPRE. Now chose SW from the (R*/SW) options. The output of your CD player is now a dedicated sub woofer output. I hope this is what you meant. There are many settings regarding the sub woofer and generally the sound in whole. Getting the manual is highly advisable.
on the back of your receiver is a subwoofer pre-out, connect one cable here, and connect the other end of this cable to your subwoofer - line level in. (depends on your subwoofer and receiver) but that's how mine is connected. yours will be similar.
Your receiver should have an RCA connector on the back panel that will be marked "sub woofer" or "LFE out". That connects to your sub woofer with a standard RCA type cable. Also, some powered subs have left and right speaker level inputs and outputs in which you would indeed run the sub woofer through the speaker outputs. The down side of that type of connection is that the line level converter inside the sub woofer will take a slight amount of your receiver's output power, although that is rarely detectable. Also, if you have a Dolby Digital receiver, using this connection method will take away systems ability to accurately control the low frequency effects of a soundtrack.
I felt supid this morning.
I bought a high end cable for my subwoofer.... and it did not work but a regular RCA Cable did. When I went to put the cable back in the package I saw an arrow pointing one way, I turn the cable and it works great.
