I just did an outside show with my full system and I thought I would get more SPL than I did. I was at about 98 db at 20 meters. Here is a description of what I am doing:
When I hit 0 to + 6 db on the console, the amps are at 0. I haved not changed any of the sensetivity settings or cut db in other places, except eqs of course.
I am currently using 3 I-Techs: a 4K for highs, a 6K for Mids and an 8K for subs. I set up my system using anywhere from 1 main box and one sub per side to three main boxes and three subs per side (the full system). The main boxes each have a 200 watt horn and a 800 watt driver, program watts at 8 ohms. The subs each are rated at 1200 watts at 4 ohms, program. I've set up three different presets using the IQ software so the amp's limiters would match the 1, 2, or 3 box per side configuration. I figured the nominal impedance and the peak voltage using the appropriate formulas so to properly (I believe) set the average power limiter and peak voltage limiter. Here is an example:
3 main boxes and subs per side: 4k- average power limiter 300 watts @ 3 ohms, 79.89 peak voltage, 6K- average power limiter 1200 watts @ 3 ohms, 159.78, peak voltage, 8K- average power limiter 1800 watts @ 2 ohms, 154.49 peak voltage.
So does this all sound like I am on the right track? Matching the amps with the boxes, setting the limiters?
Does setting the average power limiter to the average power of my speakers, adjusting the watts and the load for the number of boxes for each preset, overly limit the SPL the system is capable of producing? Do you feel I had my system safely producing its max SPL? Can I just use the peak voltage limiter to guard against damage and turn off the average power limiter to increase the SPL?
Sorry for the long post, but your insight in all of these areas would be greatly appreciated. I put together a worksheet with each of my system configurations that I could email if you wanted to see how I have set up my other presets.
Thanks so much,
