Although Allen & Heath dLive MixRacks already ship with a power supply, Sweetwater recommends adding a second MPS16 power supply for redundancy. That way, if one of your MixRack's power supplies fail, you can switch to the second supply with no interruption to your audio. To remove or replace, you simply remove the 4 screws securing the blank panel using a star Torx T8 screwdriver, slide the MPS16 into the slot, and tighten the 4 screws. And because the MPS16 is hot-swappable, you can switch it out without giving your event an unwanted intermission. With the Allen & Heath dLive MPS16 power supply, you can enjoy worry-free use of your dLive digital mixing system.
