Zack, the second red light is probably your compression kicking in. Check your manual to see if your amp has an adjustment. My old Peavey PA600b had an adjustment, but I don't remember if my KB300 had one or not. My KB/A50 has commpression, but no adjustment, go figure. If it's lighting up at half volume that could indicate a high gain signal (too hot)at the input or that the compressor is not working properly. If the amp is clipping as the light goes on, the comp. is working and you will hear a loss of sound, probably some bottoming out, esp. in the bass registers. Again, check your manual first. You might have to turn the master volume down on your keyboard, then adjust the amp volume and/or gain (if you have a gain switch). Try another channel.
