I turn it on and at the volume set @ U or straight up(midway) nothing comes out. if you turn it all the way up of course you get alot of buzz and barely get any sound from a mic or mixer signal,etc. could it be a solder problem or something. i dont think its the amp, because the volume makes the buzz get alot louder when the volume knob is turned up

Make sure you are using BALANCED line to this... XLR connections boyh ends. Make sure ALL interconnected devices are powered from the same receptacle or power conditioner. Test your cables... they do go bad. This unit REQUIRES line level input. Do NOT expect a mic to drive it directely. Make sure your mixer uses the XLR outputs and is powered from the same receptacle, even if you have to run an extension cord to it. This is a bi-amped speaker so there are independent amps for high and lows. With nothing out and known good in there is very little electronics before the signal is split to the separate amps. At line level, your volume control should probably be about 2 o'clock with the EQ's straight up flat.
