Expansion
If 16 channels are not enough when summing, the expansion input can be used as another stereo input. The output of another MixDream or MixDream XP can also be connected here.
Mono 1 - 6
The channels 1/2, 3/4 as well as 5/6 can be switched mono, so that two signals can be converted by one D/A chip. For this purpose, the signals that are placed in the phantom center of the stereo mix (e.g. kick, snare, lead vocal, bass) are panned hard left/right in the DAW.
Inserts On
This allows all inserts to be switched on and off together.
