MickyMcD Posted March 14, 2010 Report Share Posted March 14, 2010 G'day buddy, Behringer instrument amplification has a notorious reputation for this kind of behavior. It is very possible that the amplification stage was only designed to be stable at an eight ohm load, and no lower. You may have possibly blown an output device or more from driving loudspeakers the unit was not designed to drive. Also possible is that by letting it sit for so long, the internals have given up the ghost. Behringer does not use high quality components in their instrument amplification range, and it would not surprise me if the capacitors on board no longer hold charge. For many B-factor (Behringer)products, you can't really trust their reliability. It's like trusting a Firestone tyre tube around your dong to protect you from an infection when you jump in a pool of liquified herpes.

MACnonsence6 Posted March 19, 2010 Author Report Share Posted March 19, 2010 i do think that one of the caps has given up becouse if i power it on it pops then humz which tells me the cap had charged then discharged? also if i turn it on then unplug the fuze for the speaker it does nothing for a second then pops again wich again leads me to think its a bad cap. is there a way to replace the cap or how would i do more checks to make sure thats what it is. thanks for your reply I picked up an MTX Sw1212 powered subwoofer today.
