Rolls' DB225 is a transformer balanced, passive professional direct box.  It features a Ground Lift switch for hum elimination, and an Attenuator switch for padding the input signal from -20 or -40dB.  Padding the input signal provides a way to connect the DB225 to a line level signal, even a speaker level signal and connecting it to a balanced line or Mic input on a mixer.  The two 1/4" inputs are paralleled pass-through to also send the input signal to a tuner, pre amp, etc.
