20 Most Recent Yamaha YST-SW320 Subwoofer Questions & Answers

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

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

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.

hello,

First check that any muting control is not activated. This might be a button on the remote or set itself. If you have a headphone jack, it may have dirty contacts as plugging in a headphone usually mutes the speaker.

Test the loudspeaker by disconnecting one of the wires (with the power off!) and measuring its resistance with an ohmmeter (it should be less than 100 ohms - probably less than 8 ohms). Or momentarily touch a 1.5 volt battery to the speaker terminals - you should get a click or pop from the speaker.

Next, trace back from the speaker output terminals to the circuit board and look for bad solder connections or a loose or dirty connector.

If these tests do not reveal anything, you probably need a scope (or audio signal tracer) and schematic. Or at least the part number off of the chip. Is the final amp a chip also or just a transistor? Have you tested the audio transistor? If there is little or no buzz from the speaker, that would indicate a problem fairly near the output. If the tuner/if were bad, I would expect some noise/hum pickup from the low level audio stages. Get the part number off of the chip. If it is in a socket, check the contacts for corrosion or looseness.
Hope this will help...

"Opening" ... Please explain what you mean.

Yes if it has a suitable speaker connection available and is nominally 8 ohms impedance Speaker and AV.

Being from 1985 or there abouts, it probably needs some TLC at a Yamaha service centre. May need new capacitors and resolder dry joints for age related issues.

WD-40 ... Very dangerous as it not only flammable when wet but is bad for electrical contacts as it leaves a residue behind that does not conduct electricity very well. Check speaker connections first.

(francais) hello in my issue the probleme was a little resistor r027 it's in this red zone and very ugly. easy to find. a friend was unsolded the resistor and weld a little wire after wash with isopropanole alcool. the resistor test the tension when we plug usb thing. less the resistor the usb ports don't work. you can buy r027 for 2 euros for 100 pieces.... or 2 euros for 5 10 pieces (funny).

Follow the procedure as given in following link. RX-V6A ' ENJOYING IN MULTIPLE ROOMS (ZONES) (yamaha.com)

Question edited for clarity, full make model (what it is)'. Question moved to Yamaha Audio. It may be sympathetic vibration and is coming from something nearby. Put it on a folded towel or sit in the floor to test it. https://www.google.com/search?q=YST-FSW050+bad+vibration ..

You must repair the amplifier first. Take it to an authorised Yamaha service centre.

Visit 00_HTR-5750_U_EN.book (yamaha.com) and see page 59 (Troubleshooting).

Visit YAMAHA P-155 P-155S P-155B SM Service Manual download, schematics, eeprom, repair info for electronics experts (elektrotanya.com) for service manual. Check the pre-amplifier and power amplifier section.

You can't do this. The SpeakerCraft is a standalone amplifier. The Yamaha is a Receiver and has its own amplifier. Putting amplified sound into a data input is not recommended and will cause component damage and overload 'clipping'. https://www.google.com/search?q=SpeakerCraft+BB275 https://www.google.com/search?q=Yamaha+5.1+receiver I deleted the two answers from AI Answer Bots as they are not doing you any favours suggesting it can be done in their waffling answers! ..

Thanks for the compliments Gilbert. You have tried the reset so a Yamaha audio tech is the answer. This link will find you one close to where you live. There is probably a glass fuse on the power board, but you have to find out WHY the fuse blew? It is worth fixing in my opinion. https://www.google.com/search?q=yamaha+audio+repairs+near+me It does have a thermal fuse https://www.google.com/search?q=yamaha+rx-v663bl+no+power+on ..

Question edited for clarity and all the typos. The Yamaha receiver has to have a sound source and the speaker wires connect the two together. Receivers often have a a switch for Speaker set 1 and Speaker set 2, so you can send the music to two different rooms. Make sure you are on the correct set. These are supposed to be standalone television speakers by the looks of it connected to what they call an 'AV Processing Unit', I would guess more commonly called a Surround Sound Theatre System. Expensive speakers at $900. https://assets.kef.com/uploads/files/en/series_pdf/T301_T301c.pdf https://www.google.com/search?q=kef+t301+no+sound+from+speakers https://www.google.com/search?q=kef+t301 ..

To connect the Bluetooth music receiver to your Yamaha RX-V1800 amplifier, you will need to use one of the available input options on the amplifier. The Yamaha RX-V1800 should have various audio input ports, and the specific connection method will depend on the output options provided by your Bluetooth music receiver. Here are the general steps to connect the receiver:

1. Identify the audio output options of the Bluetooth music receiver: Check the output ports of the Bluetooth receiver and determine what type of connection it supports. Common output options include:
   • 3.5mm headphone jack (analog)
   • RCA (analog)
   • Optical (digital)
2. Choose the corresponding input on the Yamaha RX-V1800: Depending on the output options of the Bluetooth music receiver, you need to select the appropriate input on the amplifier. The Yamaha RX-V1800 should have various input options, such as:
   • AUX (usually a 3.5mm stereo input)
   • CD (analog RCA input)
   • DVD/BD (analog RCA input)
   • OPTICAL (digital optical input)
3. Connect the Bluetooth music receiver to the amplifier: Use the appropriate cable or adapter to connect the output of the Bluetooth music receiver to the selected input on the Yamaha RX-V1800. Here's how to do it based on the different output and input options:a. If the Bluetooth receiver has a 3.5mm headphone jack (analog output) and the Yamaha amplifier has an AUX input (3.5mm stereo input), use a 3.5mm to 3.5mm audio cable to connect them. b. If the Bluetooth receiver has RCA outputs (analog) and the Yamaha amplifier has corresponding RCA inputs (CD or DVD/BD), use an RCA cable (red and white connectors) to connect them. c. If the Bluetooth receiver has a digital optical output and the Yamaha amplifier has an optical input, use a digital optical cable to connect them.
4. Set the input source on the amplifier: Once the Bluetooth receiver is physically connected to the amplifier, you'll need to select the corresponding input source on the Yamaha RX-V1800. Use the amplifier's remote control or front panel to select the input source you connected the Bluetooth receiver to (e.g., AUX, CD, DVD, OPTICAL, etc.).
5. Pair and play: Turn on the Bluetooth function on your iPhone, put the Bluetooth receiver into pairing mode, and pair it with your iPhone. Once paired, you should be able to play your music from the iPhone, and the audio will be transmitted to the Yamaha RX-V1800 amplifier for playback.

Please note that the specific labels of the inputs on your Yamaha RX-V1800 might differ slightly from what I've mentioned, but the general concept of connecting the Bluetooth music receiver remains the same. Always refer to your amplifier's user manual for the exact location and naming of the input ports.

It looks like the P38 is the powered Sub Woofer to the Lifestyle 38 system.
