[QUOTE="Helge A. Bentsen, post: 2359, member: 263"] I run a pair of Danley SH-50s with a QSC PL 9.0(voltage gain 32dB), processed by a Lake LM-26. Sounds good, no issues with broken drivers etc. so far except one crossover capacitor that needed replacement. I've set my MaxRMS limiters for 1000w@4ohm(6.23dBu, 63,18V) and MaxPeak at 2000w(9.23dBu, 89,24V), and all is good. Up on browsing through my collection of old datasheets I came across the old spec sheet for a SH-50 stating that it's a 6 ohm box, not 4 as the new datasheet says. I remember Ivan said that the change in ohm had more to do with end users having difficulties setting their limiters for 6 ohm operation, than any actually design changes. So I tried redoing my limiters for 6 ohm operation and I calculated a new MaxRMS at 8dBu( 77.45v) and a new MaxPeak at 11dBu (109.42v). Looks plausible to me, but I thought I'd run these numbers by you guys to check my calculations. Is my numbers way off? Do you guys treat the SH-50 as a 4 ohm box, 6 ohm box, or doesn't it matter? What’s your recommended limiter setting for it? [/QUOTE]
