The ASL active DI-box is phantom powered only and is designed to satisfy the needs of professional users, operating in the various fields of the pro audio industry such as Broadcast, Recording and Sound Reinforcement. The unit is comfortable and safe to operate and it does not affect the quality of the original signal path. By having a transformer coupled DC-DC converter and an output balancing transformer on board, there's always 100% galvanic separation between the input and the output of the unit.
