[QUOTE="Tim McCulloch, post: 18994, member: 67"] Re: Amp input sensitivy The I-Techs have both peak voltage and RMS ("power") limiters, and they offer different types of protection. The PVL will prevent cone over-excursion on peaks (kick drums, dropped mics, that kind of thing) whereas the RMS limiter is designed to keep you from applying more long-term power than your voice coils can dissipate. FWIW, we primarily use the PVL (they're preset in the VerTec V4 files). In the VerTec setting the RMS limiter is not engaged, nor are the numbers that appear S.A. correct for the pass bands.... I think that tells us what JBL considers important. We haven't burned up a coil to date. If I were in your position, I'd knock down the XTI inputs by 6db (internally, using System Architect) and set the I-Tech sensitivity to 28db. While I would normally agree with Silas' comment about setting the max analog input level to +21, in your case you'll never get close before you're clipping the XTIs, so you can safely leave it at +15. Have fun, good luck. Tim Mc [/QUOTE]
