Wow - I hope this is sarcasm.....[My preamps currently take up 21u of space] -- I would think you may want to consider using some different mic-preamps!!!
[Most are 2ru tall at 3 channels each] -- My mic-preamps are 1U high and contain 8-channels each!!! By the way.....are these all -- vacuum-tube -- mic-preamps??? Why are they so big with so little electronics in them? Are they custom-built? Or, do they have a "brand-name" to them?
BUT!!!.....to each their own!!!
