OK Clear - so in a scenario, where a performer is changing his instrument settings, during a production, and overloading the input, you can’t change this, IF the source is connected locally? Hmm.
In this particular case, I would have to grab an XLR-to-TRS cable and adjust its input gain level in total… in mid-production? In between songs? (not) OK.
Essential design flaw if you ask me. On all the analogue A&H mixers I worked with, there was a +48V and a PAD button on each channel.
I now wonder if it is indicated - let’s try this TRS input. Negative. Not indicated on the screen.
But you can (?) select it on a box connected through the SLink? And is it indicated in this config?
But it’s not uncommon for combo jacks to expect different levels for microphones (XLR) and line-signals (TRS).
Yes, you should generally determine during soundcheck whether you have a source that sends line-level signals and then use an adapter cable if necessary.
But you probably opted for a stripped-down QU for price reasons.?
The SQ, for example, has a pad button for each XLR input, but it doesn’t have combo jacks and costs significantly more.
With an SLink input, you will, of course, have a PAD button to switch the attenuation.
