[QUOTE="Phil Graham, post: 24952, member: 430"] Re: Help me understand system limiting- setting it BJ, I have attached an Excel spreadsheet I wrote that will help you calculate things like amp input level to reach limiting. You enter the things in gray for the amplifer, and the spreadsheet calculates the things in blue. As you play around with the spreadsheet, it should help solidify things for you. [ATTACH]149606.vB5-legacyid=950[/ATTACH] Finally, remember that your amplifier is a voltage source. If the amplifier puts out 1000W into 8 Ohms, but only 1900W into 4 Ohms, the amplifier's voltage gain [I]has not changed[/I] from the 8 Ohm load to the 4 Ohm load, but the limiter has made the apparent voltage gain at 4 Ohm seem smaller on the spec sheet.
