I would find it very helpfull if there was a loudness Treshold alarmer when the material starts pumping. (in the form of a read bleeping light or so) As read in the manual, there is a treshold were further increasing the loudness via the input knob starts effecting the output with pumping effects. Although I am also using my ears and have a solid monotiring system, I have noticed that I cant always hear when the input knob starts hitting the treshold. To solve this I check my masters on different soundsystems. Therefor it would be very handy if such an alarm would be present. (This problem I also had with other limiters. So its not specifically related to Xenon)
