The DB25 is a transformer balanced, passive direct box. It features a Ground Lift switch for hum elimination, and an attenuator switch for padding the input signal by 20dB, or 40 dB. Padding the input signal provides a way to connect the DB25 to line level signal, even a speaker level signal and connecting it to a balanced line input (not a mic input) on a mixer. The two 1/4 inch inputs are paralleled for guitarists to "pass-through" their input signal to a tuner.
