U-Phoria UMC204HD : documentation, documentation. oh... and documentation.

the one and only bad thing about this (and other) behringer products.

the obvious does not have to be documented.

but if the implementation is quite different from what one would expect....

thats when documentation is needed.

in this case,

1) it says in the doc that main outputs are meant to be used for mixing and playback

thats true. but when they are plugged in, it also stops input into the USB

interface. so your DAW will NOT get the input signal from USB ......

2) a simple one liner stating :

NB : PLEASE BE AWARE :

the playback outputs (Jack / RCA ) ONLY output the incoming signal from the USB audio interface, NOT the mic/line inputs !!!!!

these two

would have saved me half a day wondering what I did wrong....
