The DI-1 is a high-quality direct box with crystal-clear sound for transforming high-impedance, unbalanced instrument outputs to the low-impedance, balanced inputs of a mixing console.
- Active direct box with superior frequency responce to conventional transformers
- Operates on a 9-volt battery or phantom power from a mixer
- Phase reversal and ground lifting switches
- Three input level switches
- Sturdy, compact design
