Hi
on this page of the website
https://www.ilive-digital.com/system_components.htm
it gives the folowing spec
iDR-32 IDR-32 MixRack - Fixed format, 48 mic/line in 24 out
iDR-48 IDR-48 MixRack - Fixed format, 32 mic/line in 16 out
is the description the correct way round , I was under the impression that the iDR 48 was 48 in 24 out
