Product Highlights
  • Transformer Balanced
  • Rotary Attenuator for Padding Input
  • Ground Lift Switch

The DB25b from Rolls is a transformer balanced, passive direct box. It features a ground lift switch for hum elimination, and a rotary attenuator for padding the input signal from -20 or -infinity dB. 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 pass-throughs to also send the input signal to a tuner, pre amp, etc.

      Comments about Rolls DB25b - Passive Direct Box:

      We use these DI's for PC Audio interfacing, and found it much more cost effective to purchase these units, and Patch Cables, rather than a $ specialized PC DI...you still get a stereo output to send to a mixer, but for a fraction of the price of a conventional PCDI. Pretty Small too, will fit in a mic bag if need be. Love em so far!

          Comments about Rolls DB25b - Passive Direct Box:

          I bought the DB25 so that folks in my church could plug a DVD player or a computer into the sanctuary sound system. The key here is that it had to be very simple and intutive to use. THe DB25b fit the bill perfeclty. Without any instructions, our pastor was able to successfully plug this unit into a microphone jack, and then plug a DVD player into the the DB25b. It worked perfectly on the first try. And, the attenuation control let him adjust the volume directly from the db25b. He said that he had been waiting years for something like this. Simplicity is beautiful in this case. Highly recommended!

              The DB25 is a great item for those folks with severe ground loop problems. With the adjustments you can clean up your signal with accuracy and clarity. The product is very to connect. You can't hook it up wrong. I've worked at a lot of different venues, this product insures no extraneous noises more than what I am producing. If you have a ground loop, you need this product.

                Comments about Rolls DB25b - Passive Direct Box:

                I have bought two of these boxes after doing a lot of research and reading recommendations from pro audio installers. I use them at my church for taking the audio from our computer for input into our mixer.

                The Attenuator nob is very high quality, is not loose so it does not get bumped off setting. It is great for getting the right input level into your mixer.

                The box is compact so it does not take a lot of room to store.

                Solid reliable jacks.

                Very clear sound from it.
