In Itech Amps is the Input Peak Voltage limiter really an Output Peak Voltage limiter?   What I am trying to do is limit the output of the amp to the speaker. Don't want a bunch of JBL fried speaker componets coming back to the shop, it gets expensive that way. I am setting up new control pages for all of the speakers/Amps we own and want to do it right the first time. The control is in the output section of the amp so input verses output lingo is   .

To put it simply the Peak Voltage limiter is both an output and an input function.  

The Peak Voltage Limiter does provide controls allowing you to set a peak output voltage limit for the amplifier. This is done however by sensing the Output signal and controlling the Input signal .

That's why the Output Peak Voltage Limiter is also labeled as the Input Peak Voltage Limiter .

Thanks, the head audio guy and I were a little confused. We are sending out our gear and we are not going to be there and wanted to set the limiters, so they don't wipe out our speakers.  

So one more question, how much lower than the peak limit should the threshold be set? The manufacturer, another Harmon group co, say's 56 volts for the highs       (Guess you know which box I'm talking about. )

Well..........I hate to play dodge ball with this one but I don't know of any golden rule of voltage headroom for Peak Voltage.
I would have to go along with whatever the speaker manufacture {who ever that may be   } recommends. After all who would know their products better.

Got it figured out, was just over analyzing.
