I want conect speakers - Yamaha YDP223 Digital Piano

Ok,

Add more info, how to connect to what? Speakers? audio source? Both?

You have probably blown the speaker... swap left and right to verify it is the speaker... These speakers are NOT too well suited for bass... They typically have low impedance speakers in series. You run a risk of popping the amp running with a blown speaker. You MAY have to replace all the speakers in the defective cabinet. ALL the speakers must be identical. The Passport 250 uses four 2 ohm speakers in series... not sure about the 500. It may have two 8 ohm in parallel. Do not use the speaker until it is fixed... the amps are hard to repair if a defective speaker cooks them.

I have done a lot of searches for any information on this unit and cannot even find a user manual to get information to help you. A 100 watt convertor sounds like it is too large and may not be the right one. A light coming on for a second and going off could be just the discharging of the power supply capacitors. I am sure others are searching for information and this is a poor company to not have even a manual available online. Do remember this only has a 6.5 inch speaker so don't expect it to be as loud as a larger guitar amp. If you can get photos of the connectors I might be able to help you, but with no manuals or other info the experts here will not be able to find any information. These amps are only $60 new. If a fuse went, there is another failure causing it. I will try a few more times to find at least a manual.

A large amp like this likely has protection circuit (probably a relay) that doesn't connect the speakers until the amp is stable and balanced. You relly need the schematics for the amp.

For the whole mix, there are two XLR (mic cable) sockets on the back panel labeled 'Main Output' Left and Right, if your amp has XLR inputs you should use these. Otherwise there are two jack sockets labeled 'Main Out'.

This is a complex desk with a lot of useful options, you're going to have to spend some time reading the manual. Have fun.

there is a main output, conect it to the aux in line or to the microphone line.good musics

First off it's outputs to your speakers. If you had an extra set of powered or amplified speakers you could "Y" cable your speaker outputs. Your passive speakers won't work without an amp. You really need powered speakers or an amp for your extra speakers. (if you had powered/amp'd speakers you could run them off one of you "aux" out for monitors. Do not daisy chain your speakers connecting twi together, you'll change the resistance/ohms and damage your speakers. Trust me, I do this for a living.

use 1/4 inch speaker cables. hook one speaker up to "main 1 R" out and the other to "main 1 L" out. if you have additional main speakers, hook them up the the "main 2" outputs.

look for the "bridge amp mode" switch and move it to the "main L- main R" position.

• CHECK THE CONECTING WIRES ON BACK WIRE MIGHT BE LOOSE OR BROKEN.

I am not 100% sure but have you located any speaker protection fuse at the rear of the amp ?? I know this sounds simple but if its a combo,is the speaker conected to the amp output or have you tried a different lead to rule that possibility..it happens often to me and i am like''oh no this is broke'' and its often leads broken or pulled out by cats [in my case!!!] Good luck
