Very simple - I have an Presonus HP4 headphone amp and a Quantum 2626. I have TRS cables plugged in the back (5&6) in the line output section, then going into the input of the HP4....and get no sound.

If i plug the HP4 into the front of the 2626...the headphone outputs...the HP4 works. If it matters...using logic x and an M1 mac.

What am i doing wrong , or not understanding?

Thanks in advance,
Best

Are you routing some audio from Logic to outputs 5 and 6? If you don’t, it defaults to main 1-2 and headphone…

I have no routing in logic set up.
Main our L and R are for my speakers. Pretty sure i tried line outputs 1 and 2, and the headphones did not work. Only the front headphones output works when i plug the HP4 in those.

im routing channels via sends in logic to line output 5&6, and the hp4 plugged into line output 5&6. This works. I guess it was different with my old firestudio.

Great!

Should also work with 1 and 2 the same way.
