This even sometimes being JBL's or Harmon Kardons. |
I wanted to set up a CD player and speakers in shrubbery front of house to play patriotic songs/music on the days I display flags (Memorial, Flag, Veterans[Armastice],Labor, etc.) and thought I'd use a cheep portable CD player and a pair of Commputer Desk speaker as they have a built in amp. First problem was the speakers have a USB connector plug rather than a wallhog DC adaptor.I over came that problem with a USB powered hub that was a transition piece (when USB was growing but your computer had only one or two USB jacks you could add this) Well, that supplys the 5V through the USB plug but no sound! When I put it back on a computer it works fine. It appears that the data lines (the other two wires in USB plug) have to be connected to something. I had though the USB only supply power to the speakers but I'm obviously wrong. Does anyone know if I can get the amp to work wiout computer? Is there a way to connect a resistor or something across data terminal and fake out amp? Any ideas would be welcome. I thought this would be a snap but I may have to go out and buy a speaker unit that has the wallhog on it . PL

Hi- Keep in mind that no matter what type of computer speaker you use, the volume is going to be pretty low outside. I'd bite the bullet and get a nice mono amp from MCM or Parts Supply, and a decent speaker, maybe even a horn.
Just a thought.

Why not just simply run some speakers out there and keep ALL the amp and electronics indoors?
Edd, the speakers that have the USB have a seperate audio. In other words same wiring only the addition of the two USB data lines as on the wallhog models. The audio, however, is fed through the seperate autio line. I can plug the USB into my computer and then fed the CD player through the audio jack and it works. So the data lines are receiving some kind of signal that tells the speaker to play but its not the audio feed. Crazy, but most likely makes sense to a computer techie. Again, thank you for your help and the song suggestions. PL
