I've done a lot of digging to see if this has been posted before, couldn't find anything. If it HAS, my apologies.
I'm using the 2nd Gen 18i20, as well as a Behringer Ultragain Digital expander thru the ADAT interface for a total of 16 mic pres.
I am using the REAPER DAW software,
I followed a REAPER tutorial on how to create headphone mixes (I want mono headphone mixes), and all worked OK. I routed the mixes to outputs 3 and 4 of the Scarlett.
When I played audio thru the system, it seemed to be going to to the proper outs. When I connected the outs to a headphone distribution amp (PreSonus HP60
, thru the external input), however, i could not get any audio into the headphones.
What am I doing wrong? Is this not supported?
