Okay, Boost/Pad in I/O is also new.
Manual:
"OUTPUT 1 BOOST/PAD (0-18 dB)
Firstly, this is NOT a boost intended for use during musical performance, as you might find on an amp or pedal. Rather, this parameter is designed to boost signals to the OUT1 D/A converters so they can operate as close to full-scale as possible, while simultaneously padding converter outputs to lower the noise floor. To set this control, increase the boost/pad amount until hard playing on a loud preset causes the front panel OUT1 CLIP LED to light. Then reduce the Boost/Pad setting a few dBs to prevent further clipping. Note that the BOOST amount is also applied to outgoing DIGITAL or USB signals."
I'm a bit confused about configuring this. I guess this is only neccesary when all user presets are set way below clipping level? And doesn't this impact headroom?
