MOTM is about 13dB. I'm not sure what those numbers mean, but I'm
guessing the lower number is minimum full scale (below that the S/N
goes out the window), that clipping the analogue input is not much of
an issue, and the input knob is before the AD.

Well, most mixers should be able to send a hotter signal.

It shouldn't, although it might reduce the level slightly. While
Lexicon boxes generally have rather high input impedances (higher
than many other effects), afaik, the "unbalanced" setting has a lower
impedance than the "balanced" setting.
>The outputs are +18 dBu at max scale. I'll just have to try it.
Unlike most Lexicon boxes, the MPX1 has the convenience of an output knob :)

Yes, the MPX1 is rather unique in that regard. With the tap input
you can use an MOTM-650 to generate synced LFO's. My PCM-80's can't
do that. Also, you can use the pedal input as a CV input, so you can
use an MOTM-320 as a mod source. Although, if it like most Lexicon
boxes, it doesn't like negative voltages, so you need to scale and
offset the 320 output.
