My powered subwoofer no longer works through the receiver
Here is my problem. The powered sub woofer I have for my system will no longer play using my Yamaha receiver.
I have the Yamaha Model RXV659. The powered sub woofer I have is the 250 Watt RBH MS 10.1.
At first I obviously suspected that my sub woofer went bad. So I ran some trouble shooting and have discovered that the sub woofer functions properly. If I plug it into a direct source i.e. a cd, dvd or blu ray player using the RCA connection it works perfectly fine it has power etc So, I then thought it must be the wire from where my sub woofer sits, that runs back to the receiver. So, to test this, I plugged the sub woofer in directly to the receiver by passing the in wall wire. It still does not work there is no sound that comes out the sub woofer. So, it must be the settings? I have changed all the settings and still nothing. the sub woofer itself works fine, but just wont work plugged into the receiver. While the sub woofer is hooked up it seems like the receiver does not even send it a signal now the standby mode remains that way unless I switch it on, even when the sound is playing through the speakers. All the other speakers work fine.
Here is a brief summary of how my settings are currently.
Menu Manual Setup 1. Sound Menu
A Speaker Front small, Center Small, Sur LR Small, Sur B SMl X2, Presence Yes, Bass Out Both, Crosser 110 HZ, SWFR Phase NRM, Priority SB.
E LFE Level SP LFE 0 and HP 0.
Tone Control Bass Bypass, Treble Bass Bypass
My sub woofer is set to low pass and auto. The RCA is plugged into the Line IN which it has always been and again when plugged in directly to the source it works fine. The RCA is plugged into the back of the receiver in the spot that says subwoofer.
I am lost as to what to try next. Any ideas? I am beginning to wonder if the RCA plug in on the back subwoofer of the receiver has gone bad. Is that possible? Is there a small replacement part for that? Are my settings wrong? Is there another area in the back of the receiver that I can plug it into and change the settings to bypass that RCA input that it will work if it has gone bad?
One more thing I did try. I plugged in a small subwoofer an older one I had and there was some bass that played out of it while plugged into the receiver but it was somewhat muffled, but did have some sound.
Re: My powered subwoofer no longer works through the...
If you have your front and centers set to 'small' you want your Bass out to be subwoofer only, and the rca jack labeled 'sub out' is the only place to connect your sub to if you want to control the frequencies with your reciever. I dont know the brand of your sub, or the inputs on the back of it to advise you where to connect, but it sounds like it worked for you at one time, but suddenly it does not
Hey Tad, I have the same problem and perhaps a solution. I just moved to the other SW "pre-out" and it seems to be working..the green light is on . Whatever works i guess.

Sounds like this is a powered subwoofer (as it has a line input). If this is the case, the 'sub W' output of the receiver will NOT work, as it is only sending speaker level to the line input.
You will likely go from sub W directly into the speaker input on the sub. The output is probably used for looping an additional sub into the system.
I assume you mean the subwoofer remains silent during the test. Perhaps the subwoofer is where we should be looking.
If you jack it into one or both of the Tape Out connectors and play some music with substantial low bass, does it make any sound? This would at least prove it is alive.
It is based on your sub-woofer type..whether powered or passive sub woofer..
Assume that you have powered one..RCA sub woofer jack is the best to feed it ..you should use RCA sub woofer output on your receiver as well..good luck
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.
Get a powered sub-woofer that has speaker level inputs, then run your front speaker wires into the sub-woofers speaker level input and then run a set of speaker wires from the sub-woofers speaker wire output to your front speakers. This is a common way to use a sub-woofer with a receiver that doesn't have a sub-woofer output.
Most powered sub-woofers have these connections, just check it out first before you buy one. They look like speaker jacks on the back of the receiver.
Any powered sub-woofer will work with it. Check the back of the Technics, make sure there is an RCA output labeled "Sub-woofer" or "Woofer" or "Sub". If so, you can get any brand of powered sub woofer and it will work. A powered sub-woofer is one with an amplifier for the sub built into the box and you will need to plug it into an A/C outlet as well. The only exceptions to what will work with this unit is to make sure you are not buying a sub-woofer that is made to only work with the companion unit it is originally sold with. Many Panasonic and JVC sub woofers are like this. Just look for a sub-woofer that is not part of any system. Velodyne makes some really great sub-woofers that would work nice with yours, but they can be a little expensive, but they are very good.
If your Technics has no RCA output for the sub-woofer, you will need to make sure that whatever powered sub-woofer you buy has a speaker level input for it. Most powered sub-woofers have this feature, so that you may just run the front speaker outputs of the receiver into the subwoofer and then the sub-woofer will have a set of speaker outputs right below the speaker inputs so you can still have your front speakers connected to that and not loose anything from your system.
I hope I have explained this in a manner you will understand easy, if not just post whatever questions you may have right on this thread and I will get back to you as soon as possible.
It would also be appreciated if you could rate this solution if you no longer need any help from me. If you do require more help, please wait to rate this until we are finished. That way I do not get an undeserved bad rating when we have not even finished our communications. By the way, A "Thanks for trying" and "Helpful" rating are really not good, they always end up lowering my overall score.
THIS UNIT HAS NO SUB WOOFER AMP IN IT. THE ONLY WAY TO OVER COME THIS IS TO HOOK THE LEFT AND RIGHT FRONT SPEAKERS STRAIGHT TO THE SUB WOOFER AND THEN GO FROM THE SUB WOOFER BACK TO THE INPUTS ON THE BACK OF THE UNIT FOR THE FRONT SPEAKERS. THE SUB WOOFER THIS WAY WILL EXTRACT THE BASS AND THE FRONT WILL RECEIVE THEIR PART. THIS SOUNDS CRAZY AS HELL I KNOW BUT THAT'S HOW I GOT MINE TO WORK. THE OUTPUT FOR THE SUBWOOFER IS USELESS AND PUT THERE FOR YOU TO HOOK UP AN AMP FOR A SUB WOOFER. EVERYTHING HAS SHORT COMINGS, AND THAT'S THE ONE FOR THE AX-720.
I have a JVC sub woofer SP-pwm 505 can I use this with any system my receiver has RCA jacks it looks like this uses a S cable...is there a cable that would convert "S" cable from sub woofer to an RCA output jack in receiver [email protected]
Go to the following website www.servicemanuals.net where you can get the service manual for $17.00, unbelieveable, don't you think? The service manual should help you sort out your hookup problems. Good luck.
Tried swaping the bass to subwoofer only and that still did not work.
