HammerSlammer posted a topic in Amplifiers - General DiscussionHi. I've been reading a lot of posts and responses on this site. I must say that I am thoroughly impressed with the care, politeness, accuracy and simplicity that goes into answering of the user's questions. There are a couple explanations that I have walked away from, having no more understanding than I did when I started reading. One in particular is the explanation of Crest Factor. Some additional reading elsewhere may clear things up for me. My question is about the built-in limiter in my XLS 2500 and XLS 1000. I just want to get a clear understanding of how it works and how to apply it correctly. I know that a compressor can amplify the quiet parts and surpress the loud parts of pre-recorded music (if I understand it correctly). Reaching my hands on occasion, has been a bunch of songs burned on a CD to play at some events. Without a compressor, one song would come through so low that I would have to increase the levels to maintain the right acoustic dB level for the gig. On the same CD, the next song would begin to play and it would be so loud that I'd have to quickly move the levels down. So I either have to have a real quick hand, or use a compressor so I can be on auto-pilot as far as that's concerned. Does the limiter on the XLS work like this? I'm thinking it does in a way more electrically to protect the speakers, rather than to maintain and even-out the acoustic dBs to be at a certain level. If I do use the limiter in the XLS, then my overall acoustic dB level would be lowered? Can you explain how this works in a simple way, and also explain how to set the limiter on the XLS? Will the integrated limiter benefit me in either of the following situations; please explain: (1) 500W RMS speaker 1000W Program 1500W Peak- with an XLS 1000 bridged (under-powered) " " " - with an XLS 2500 bridged (over-powered)
I'm getting ready to install a couple of the new XLS units for live use. I usually use a well set compressor/limiter (Ratio: Infinity:1, Attack: 5 ms, Release: 1s) , to protect speakers. It is quite common for my clients' operators to (attempt) run a system 10-20 dB over what the amps (and speakers) are designed for, to try and get it "just a little louder". The compressor/limiter I typically use provides 30+ dB of reduction, so even though things may start to sound squashed, the system is protected. 1. Is the built in Peakx limiter suitable to handle this kind of abuse, or should I continue to use an outboard limiter? 2. What is the relationship between between the clip LED and the Peakx limiter? 3. Can you provide specs. for the Peakx limiter (threshold, attack, release, max amount of gain reduction, etc) Thanks, Chris
Hello everyone! This forum is extremely helpful but I'm having trouble finding some specifics for my set up. I have an 2x iTech 6000 and an XTi 1000 driving 2x Peavey QW218 and 2x QW4F with the tops being in biamp mode. I have the iTechs in stereo on subs and mids and the XTi in stereo on the tops. I'm happy with the settings with respect to crossover points and delays, etc., but have I don;t know how to set the limiters. I blew both subs and a horn, so I want to set the limiters to help keep that from happening again. I understand that this isn't a catch-all for clipped signals but I'd like to get as much protection as possible. The Peavey subs are rated at 1600/3200/6400 watts and the tops are 1200/2400/4800. Can anyone help me with the best settings for the peak voltage and RMS limiter settings? Thanks! -Mark
