Yes, I found these online this afternoon:
DB25 XLR PATCH BAY
Something like that... I've got a pair of MOTU 896HDs and 16 channels of "slutty" preamps in a rack and I just recently custom assembled Canare braided shield starquad cables from each preamp's output to the MOTU inputs. It's neat and tidy for the first time in several years. :-)
I think my next purchase may be a Lynx Aurora 16 and although I see the merit and flexibility to the Dsub connection I don't look forward to my rack becoming a mess again. That's why I was thinking of something like I linked to above.
Are there other brands? Or is it more likely to just be a custom fab?
thanks,
mike
