Rolls DB25-B
DB25b Direct Box with Ground Lift


The DB25b from Rolls 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 DB25b 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 for guitarists to pass-through their input signal to a tuner or preamp.

  • Output impedance: 600 Ohms
