View Full Version : Help: No output from crossover ... might be blown

03-23-2007, 01:39 PM
My right mid on my cdt ef-61cf comp set stopped working last week. and I finally figured out why. The a few stray strands of speaker wire connected to one of the terminals on the mid was touching the metal on the frame of the mid.

I noticed when testing the wire from the mid at the crossover, it would spark up when it touched any of the metal connectors.

So I'm guessing this blew the mid output on the crossover. So my question is, can this be fixed easily. I opened up the crossover and I don't see anything wrong. Nothing appears to be fried. It is a SATNET 400 crossover. Here is a picture:
I'm probably just going to buy another set of crossovers, but if this was an easy fix, it would last me until I got another set.

Try measuring the resistors. If they're OK, look under the board for some melted away solder or burned track.

Do you smell any burnt areas? Did you remove the board from the housing and look under it? Post a picture of that as well.

Nothing smells burnt on it.

Left side, near the center (3 solder marks together) furthest to the left looks damaged. Also, looks like condensation stains to me, did you have it exposed to moisture?

I'd agree with above as well. Test it and look for weak solder (one mentioned for starters)

Your midrange components are the coil opposite the terminals, the capacitor next to it and the small ceramic resistor.

The track one third down on the right in that last board photo, looks melted away. It looked too thin anyway. You might need to make a wire bridge from the lower right (the coil) to the fourth terminal from the left (mid out).
