Outputs protect

Hello!

I wanted to try to listen to the filters on individual outputs because I got a mixer.
I plugged all the wires into the mixer and turned it on. Phantom power was turned on on the mixer and it was supplied to 8 outputs for 2-3 minutes.

The sound works but I have no way to check if I damaged the phase.

I decided to check whether the s2400 has protection against phantom power, but I couldn’t find any information either in the manual or on the forum.

Please tell me if anyone knows!
