[QUOTE="Ryan Lantzy, post: 27453, member: 7"] Re: Thoughts about amplifiers at 3/4 volume. I'm not going to contrdict Meyer engineers, but if you are using the M1-A processor there are sense lines that connect from the amplifier output terminals back to the processor. I'm not sure what the amp gain has to do with it. The processor should just be looking for a peak voltage (or other undesirable condition) to begin limiting or corrective EQ. For instance, older Nexo processors that have sense lines also have a amp gain adjustment (26, 32, or 38 dB) but the manual states that this has no bearing on the limiting or protection, it just helps to adjust the output of the process to be more inline with the amplifiers gain (i.e. pad to correct gain structure). Additionally, I don't think using XTi amplifiers which have a DSP stage (and AD/DA stages) with a processor that has amp sense lines is a good idea. The delay in the audio processing incurred inside the DSP of the amplifier will throw off the calculations/comparisons being done by the external speaker processor (if sense lines are being used). I've never set up UPAs myself or used the M1-A processor and I don't know which Meyer processor you are using for certain, but these are just some friendly warnings for you. [/QUOTE]
