I have a w7 keyboard ,given to me free,but with no owners' manaul,when I plug in amp there was no sound coming out I do not why?

You may have a blown voice coil in the speaker. Can you see the back of the speaker? Then, First Check the connections to the speaker and make sure they are well connected. If they are, then the speaker is probably at fault. If you are handy, then you can get a replacement speaker, 12 inch?, and swap it out.

Check with a small speaker or amp plugged in the back. If you can hear it then the jack in the back is probably not making contact. If no sound comes out there then the Audio Amp or it's circuity in the organ is more than likely to need repair.

Check the output socket for corrosion, this would stop the sound from getting to the amp. Plug in an output cable and wiggle it around to see if it works intermittently. Plug it in and out a few times and see. We are looking for a dirty connection.

Greetings! Ok, your amp has an XLR (3-prong) Low-Impedance input on Channel 1 for a Mic. All the other inputs are 1/4" High Impedance inputs, which are for instruments and/or other High Impedance items including low quality High Impedance Microphones. The SM48S is a high quality Low Impedance microphone, so if you use it with a 1/4" plug, it will be in a High Impedance channel, and will be very LOW in volume in comparison with everything else. So, you must use an XLR (3 prong) cable from the Mic to the Channel 1 input on your amp. That will do the trick. Good Luck with your new amp and Mic!

It sounds like to me that you blew the speaker. We here at Pro Line Music are Peavey dealers. If you can not check for continuity of the speaker you can bring or send it in. 215-736-8055

Do some tests: Plug a set of headphones into the line outs and tell us which ones if any have sound. Note that only one side of the headphones may have sound and it may be low volume. We need to know if anything is coming fromt he preamp. Makesure the output switch is set to one of the speaker on positions and not just phones.

If this ties to a keyboard, make sure the keyboard and this are BOTH plugged into the same receptacle. You should send a higher level from the keyboard (turn volume up to around 70% or so) and use less volume at the input gain of this amp. Use more at master volume if the amp has one if needed. If the hiss is there with NO input cables plugged in and input gains at 50%, that is objectionable, the amp probably needs servicing. Unused channel gains should be clear down.

Have you tried headphones? - did it work or still silence?

what the #full Model number of this keyboard?

Page 8 of the owners manual explains this and suggests that if their procedure fails to take it into an authorized Fender dealer for service. The manual is dowloadable at Fender.com/support.

I'm looking for parts for the Yamaha W7 keyboard.
