Control your Distortion.

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, so the audio mixer input does not distort. Padding the input signal provides a way to connect the DB25 to a 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" inputs are paralleled for guitarists to "pass-through" their input signal to a tuner

Rolls accessories are well-known throughout the world. They make all kinds of specialty signal adapters, phantom powering devices, a very versatile cable tester, a signal generating device, and more. Many of these little boxes are the result of customer suggestions.

Just works with no hassle

Comments about Rolls DB25b Direct Box/Pad/Ground Lift:

I use this on most gigs (8-10 a month) - with no battery to worry about I know it will always be ready. The dB pad is handy for sound guys who think the signal off of my amp (which is where I input to this from) is too hot, and I usually keep the Ground Lift on. Small size fits easily in my gear bag. I'd buy it again, and am about to get a 2nd one for my wireless mic connection.
