Question about Yamaha YST-SW012 Subwoofer

1 Answer

Yamaha yst-sw012 power but no sound

My sub is turning on and getting full power but there is no sound coming out of it. We have checked the volume control on the unit as well as on the Yamaha receiver (receiver htr-6230). We have also just replaced the input cord (rocketfish 12 ft subwoofer cable, rf-g1214). If there are any troubleshooting tips or commonly known problems that I could try to fix I would love to do that and keep the original sub with my surround sound instead of completely replacing it.

SOURCE: Yamaha YST-SW320 subwoofer won't play sound

I too have amplifier and speakers thatI rent for parties, and sometimes when I connect them they don't work and I battle with them for hours before I find the out that its just a little thing that happened, like speaker wire might have cut inside, or the wire conneted for the CD to Amplifier is bad and son on.

But I will advice that you test your amplifier and woofer, with another equipment independently to be sure if they still working well or not. As this will help you to know what to do next.

May somthing happened to one of them the last time you used it and you did not notice, and it might just need some servicing.

Best wishes

SOURCE: i have a yamaha yst sw320 subwoofer connected to

Subs don't go to a variety of connections on the amp. Let's stop guessing and stick with the prescribed one.

Register and download the manuals for free at retrevo.com

See page E1 regarding placement and safety.

http://www.retrevo.com/support/Yamaha-DSP-A595-Amps-manual/id/319ag821/t/2/

Page 44 - read about "humming".

If you have hum on the sub, is it there with and/or without the input cable attached?

Disconnect the input(s) and see if it hums in the absence of an audio source. A bad audio cable shield or unwisely-routed audio cables will allow entrance of unwanted signals from external power sources, magnetic fields, even dimmer-controlled track lights. Sometimes, simply reversing the orientation of the ac power plug can eliminate humming.

SOURCE: No sound from my Yamaha

Feed it with an RCA cable any other audio device you may have (CD, TV, MP3 player, PC) to prove it can or can not woof. It will respond to any audio, not just LFE or subwoofer audio.

Sub Speaker giving intermittent loud crackling and sharp loud popping sounds even with main volume control turned off. Crackling sound can be reduced by turning sub volume control off.


It may be the control itself too. In time, these controls can get dust build up inside it. There are volume control spray cleaners available from Radio Shack or other electronic parts stores. The cheat on cleaning the control is to just rotate it from stop to stop as many times as it takes to clear the noise.

Can I and how do I hook a subwoofer to my Sony str-de705 receiver


It depends. You can connect an active (self-powered) sub-woofer to the STR-DE705. You can't connect a passive sub-woofer that needs power from the receiver. If the sub-woofer has its own power cord, then it's an active unit. See https://us.en.kb.sony.com/app/answers/detail/a_id/37001 for more information. You'll also need a RCA subwoofer cable. This is like a RCA audio cable but only has one plug on each end. (Using a regular audio cable may risk a short when the extra plugs hit something.) Many subwoofers will come with the audio cable. If you do need one, they are available at most places that sell cables, including Amazon.com .

Here is an example of an active subwoofer: https://us.en.kb.sony.com/app/answers/detail/a_id/37001 . This is the Yamaha YST-SW012.

I hope this helps.

I have a quantum audio equalizer and the sub volume doesnt work wats the problem?


are you getting any sound at all out of your sub woofer? what about if you bypass the EQ? If you're getting sound but just not the control over it then the Potentiometer (the volume knob) is bad or has become loose from the connection to the board. More than likely you would not have any sound at all if it's loose. If you have no sound and you are not getting sound after bypassing the EQ then check your head unit settings to make sure that it is set to have full frequency output of the RCA's. It may be set for high pass which will filter out the low tones, leaving nothing for the EQ to work with.

Sound is not loud


most yamahas have a setting to lower main speaker volume 10 db, accessed by the remote, or front panel controls in the settings.this is a very small sub, only a 6.5 inch driver and 100w.
sub placement in regard to the seating position is very important in order to get good bass response.

How do i make this woofer work with my polroid tv


OK, it looks from what I can tell you need a 1/4" stereo plug for the input to your speaker system. The output from the TV is either RCA jacks or maybe a 1/8" sub mini stereo jack. You can likely go to Radio Shack or an audio store and purchase a cable that has the 1/4" stereo plug on one end and a 1/8" sub mini stereo plug on the other. That cable would mute the TV internal speaker or if you do not want to mute the TV speakers you can get a cable with the 1/4" stereo plug on one end and the L and R audio, RCA (phono) plugs on the other. That would give you both. RCA plug and 1/4" plugs are pretty easy to install if can not find the correct cables. Good Luck. The Yamaha unit looks to be self powered so impedance matching or load on the TV audio amps should not be a problem.
