    Setting PA Speaker Amplifiers

    Hi, thanks to all for helping me out setting the amplifier. I decided to go with setting the FOH up in the way that the mixer and amplifiers both clip at the same point. I do have one more question, though. For our monitor amplifier, the QSC RMX1450, only the input sensitivity at 8 ohms is...

    Setting PA Speaker Amplifiers

    I just want to clarify, 15dB of attenuation means 32-15=17dB on the knobs of the amplifier, right? Also, did you mean to say 4 Ohm instead of 8? It seems (correct me if I'm wrong) but at 8 Ohm the specs say that the input sensitivity is 1.7 Vrms = about 6.83 dBu (if the calculator I'm using is...

    Setting PA Speaker Amplifiers

    Thanks for the information! It actually helped a lot to clear up setting PA gain structure, somewhere where I'm only beginning to venture into. So, for our system, the "right" way would be to set the FOH amps to 12-15db? So that at the same moment when the mixer clips, so do the amps (their...

    Setting PA Speaker Amplifiers

    That's pretty much how I was doing it. I had pink noise going out of the mixer so that the output was at the last spot before clipping. Then I used my meter to get 90-95dB SPL which was already too loud for our application. The amplifiers are far from clipping, because the input knobs are turned...

    Setting PA Speaker Amplifiers

    Hi, we just purchased a Behringer X32 (sweet mixer!) for our youth sanctuary in our church, and I decided to re-do the PA system while we were at it. I've always remembered the speakers being very noisy (hum, etc.) when nothing was playing through the system (everything was muted). Trying to...

    Yes, I know what you're talking about. The audience that is going to be looking at this screen isn't particularly "picky". In fact, I doubt that even three-quarters of them will never know that there are two projectors making up the image, if we were to continue on with this. Yes, I was...

    Just an idea, but what if we overlap the two projectors by an inch or two in the middle, and then shift the left/right images digitally to the left/right, respectively? Either way, because of the constraints of the design, we have extra on both sides that was originally to be absorbed by felt or...

    Do you guys think that there is no way that this will be a reasonable setup? If not, I will start to change the design to something else. I'd really love to have this screen work out, but it looks like either it's going to be too troublesome or not going to work out at all. I really like...

    Youth Room Stage Design

    Thanks for the recommendation. I will definitely look into that if we continue on with this plan. Are there any short-throw projectors with lens shift? I've looked around and couldn't find anything, but maybe you know something? As for content, I want to clarify on that. We will usually use...

    Youth Room Stage Design

    Well, what this screen is for is mostly worship, which consists of a background and lyrics on top. I'm not sure that for this application it always needs to be perfectly aligned pixel-to-pixel, but I do acknowledge that adjustments are going to be needed, and that colors, contrast, and...

    Although what your saying is true, won't these shifts be too subtle to notice immediately? If we had to re-adjust the projectors once a month, that wouldn't be a problem. Also, if we were to do what gafftaper suggested, there would be even less of a problem because of the frame in the middle...

    Youth Room Stage Design

    What about when we have, let's say, a red background color? The yellow in the photo is just a rendering example that I did. We plan to be able to change colors. Or were you talking about just hiding the rough join in the center with tape and having it be thin enough for no one to notice?

    Youth Room Stage Design

    What we'll probably end up doing is what ruinexplorer suggested. That way, we have a shot at the original plan but also have something that won't sacrifice too much -- a seam in the middle to cover up the unevenness in the middle. Are you mentioning that mounts will move around over time, even...

    Youth Room Stage Design

    That's a great idea. I'll draw that out, and present it to the team. If the projectors turn out to create a perfect seamless image (which they probably won't) we are lucky and won't have to create the seam. That way we'll be able to have a Plan "B" if positioning the projectors will prove too...

    Youth Room Stage Design

    I'd like to point out two things. First, this design was found at churchstagedesignideas.com -- a website dedicated to churches trying to find some inspiration when designing their stages. That's exactly what we did here. We took an idea that we liked, and made our own version of it. In fact...
