12" Speaker is Not working?
What needs to be repaired to get the 12" speaker to work again.
Never over played and never moved. Just stopped working...
Device and repair information for the Behringer Eurolive B212D speaker system.
Here's a simple procedure to diagnose this type of problem.
We assume that the amp powers up, and the horn tweeter still sounds when input signal is applied and the volume is turned up.
You should probably not try to service the amplifier yourself, unless you have ample experience in electronic troubleshooting and have access to at least a good multimeter and an oscillloscope.
The amplifier board in this cabinet has an integral switchmode power supply, which means that the board carries mains voltage, and the amplifier itself, being capable of several hundred Watts, also carries dangerous voltages. Don't mess with it if you don't know exactly what you're doing, 'cause it bites!
Hi, I just saw this very old topic and wanted to comment on it. I just bought 2 used Eurolive B215D where there was no bass. The tweeter was working fine. I found the cause so I hope other might find it usefull. I pulled out the amp module and disasempled most of it. On the amp circut board there was a lose coil, which must have gotten lose due to rough handling. So I just repaired the coil and glued and soldered it back (used epoxy glue to make sure that it would not get lose again). After this it worked perfect again :-).
Hope it can be of use.
