I've searched the forum for info on this and although i can see the topic has been covered, i still don't understand what the deal is with this. I have an Ampeg B2 1x15 Comb, i run it with an ampeg svt 4x10 cab to take it up to 350 watt output. On the combo my input gain has a red light that starts blinking when i have it up above 1/3 of the way. To make it as loud as possible iturn my master volume up to 10 with the limiter switch on in order to protect my speakers. My question is what is the deal with the imput gain? If i run that so the light blinks red will this kill my amp? Also, when i turn the limiter off it gets a lot louder but less defined in sound quality - is there a danger of hurting my speakers with the limiter off even though my exstension cab is 500 watts and the amp can only put out 350 watts top? Sorry for the long winded and probably repeatedly asked question but i could just do with an explanation of things in non technical terms. Cheers.
