moved from the german forum into this, still existing thread.
Thank you for your understanding.
Today I bought a seccond hand xb 14 with a signal Light. Hé showed a video explaning the mixer and it looks the same as the stonebox. If You raised the mic fader a red Light blinks. The telco chanel orange. And normal a green Light. Hé diddent use playout start but that can be done with a velleman kit hé told me. Next monday I’m going to pick up the mixer. So next weak I know if a velleman does the job.
