Hello...
My name is Stephan a I‘m from Germany.
Therefore - Sorry for my bad english
I‘m a absolute newby and need help:

I’m using the Presonus Quantum 2632 running on my iMac (late 2013). I connected the Quantum via Thunderbolt. It‘s just running fine.
The UC Software works fine too.
So far so good...
I‘m using 2 pairs of Monitors (2x M-Audio BX5, M-Audio BX8).
One pair is connected to Main Out, the other pair on Line Out 1/2.
Now, when I listen to music from iTunes, You Tube etc. the sound comes just only from the Main Output.
How do I get the sound parallel out of the Main Out & Line Out 1/2??? And is ist possible switching A/B?
I tried „speaker configuration“. There I used „quadrophonie setting. To test the speaker you can click the speaker and hear a noise. Sometimes it is horrible loud.
But Even I applyed this configuration, I‘m not able to chose, which pair of Speakers is running.
Best regards!
