The QU16 v1.6 user guide description and block diagram show the channel meter as post-delay, pre mute. Not sure if I am missing or misunderstanding something but it appears to me that the channel meter is actually pre HPF?
E.g. Overload the gain and peak indicators light across the channel. Increase HPF frequency control and peak indicators extinguish but the channel peak indicator continues to display. Can do the same with PEQ and Comp.
Same as on ilive and GLD: the channel meters are where the block diagram says they are, but the peak LEDs light up whenever there’s is a clip *somewhere* in the signal chain for that channel.
