Yes, that seems like it would work too. While I'm sure it's a fine
product, I wouldn't even need a MUUB board for that. Building a
summing amp would only require one dual op-amp. Although I would
still have to run power, mount it somehow, etc. Which is much more
work. Ideally, the 490 should have had an input amp with a gain knob.
Anyway, since normalling the jacks seems the easiest, most
cost-effective, least invasive option, I'm looking on opinions on
what would be the best way to do it.
