[QUOTE="BJ James, post: 25320, member: 87"] Re: Help me understand system limiting- setting it OK, It's starting to sink in. There are a lot of variables. Let's see if I can figure out what I'm doing for the ribbons(tweeters). Here are the DSP settings for them: "Ribbon: 36 Volts @ x40 gain = 0.9 Volts @ x20 gain = 1.8 Volts Threshold: -2.0 dB Ratio: 20:1 Attack: 10 mS Release: 100 mS" The ribbon is rated for 160W program (16 ohms). According to the the DSP specs, it wants to see wattage of around 80watts before limiting occurs. I plan on running 4 off a channel of a PLX3002 which will then see a 4 ohm load. The PLX3002 is rated at 900watts/channel at 4 ohms. That's a little more than I should have. And worse still if I only run 2 or 3 ribbons per channel. I guess the real answer is to have a smaller amp on the ribbons. I'm not sure if I should change anything in the limiting.... it's Peavey's DSP, with their settings, for their speakers. What would you do? BJ [/QUOTE]
