We did look into this early on and we identified that =here was not enough 110Vac 60 hz power to support a "residential" audi= system and that an inverter would need to be installed. Please do not confuse 28V power", 12 volt (13.8vdc) power and 110V, 60 hz power. On the other hand, you do have approximatel= 68 amps of 28 v power available from the aircraft side.
