Continuing my journey to learn audio ... using articles here on setting tone in the audio chain I recorded one FP-33 channel using mic level and the other line level. Not sure this demonstrates much but....

Audio Chain:
live school choir on risers -> three Shure KSM 137 mics -> Allen-Heath GL2800 Mixer -> Ashly MX-508 subgroup mixer -> Rane 216ds distribution amp -> Shure FP33 -> XH-A1

I set tone to -18dB using line level between FP33 and the A1. The Ashly was configured flat and unused channels off. The Rane DA provides line and mic level outputs so I set tone from the Allen-Heath to the FP33 at mic level on one channel and line level on the other. I think this just tested Rane/FP33 but for what it's worth, I've attached exemplar snippets from the two channels.
