The Rolls 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 20 or 40dB. Padding the input signal provides a way to connect the unit to a line level signal or even a speaker level signal and connecting it to a balanced line level input on a mixer. The two 1/4" inputs are paralleled.
