I want to use my MKH 416 T shotgun microphone with a mixing console with phantom powering. Will this work?

No, the MKH 416 T is an AB powered microphone. In AB powering, the supply current flows the same way as the audio frequency voltage, while with phantom powered microphones, the current flows back via the cable screen or shield. If you want to use the MKH 416 T with this mixer you will either need an adapter or a separate power supply unit, such as the MZA 16 T.
