Please read the user manual below the video before assembling or powering up your mixer.
If you don’t have an output signal: Please double-check that, if you are only using one Master Insert Module, the unused ribbon cable is unplugged and instead the Master Insert Bridge adapter is installed. The white mark on the adapter must be aligned to the cutout of the Master Insert connector on the mainboard and so should face to the left side. Make sure the adapter is plugged in tight.
