The DB24 from Rolls is a stereo Direct Interface (DI) that provides dual channel isolation and designed to connect high impedance devices to low impedance. The unit is completely passive, and utilizes proprietary audio transformers for superior sound.

Housed in a heavy-duty steel chassis to provide maximum reliability when used in demanding live sound reinforcement applications, the unit provides a variety of inputs including stereo and mono 1/4", stereo RCA, and stereo 1/8".

The DB24 is an ideal impedance matching device for connecting any unbalanced stereo signal to a balanced system. Consumer audio equipment such as CD players, DVD players, MP3 players, etc., may be easily connected to a professional audio system.

    Pretty nice so far

          Comments about Rolls DB24 - Stereo Direct Interface:

          Built like a tank. Have not tried every input option yet, but it splits an unbalanced 1/8" stereo output from my ASUS laptop headphone jack to left and right XLR's with no hum or noise whatsoever, with what I perceive to be very good headroom and fidelity. I was pleased to find that the level adjustment pots also worked for the 1/8" TRS stereo input, as those are usually set at -10 dBv and you have to attenuate from the source device. Provided a good, clean boost for the signal. Application: Playing click tracks into Mackie PA from snake XLR inputs; great separation from transformer isolated outputs; no batteries or phantom required. At this price, no soundman should be without one of these.

              Comments about Rolls DB24 - Stereo Direct Interface:

              Tried to use it to run from my mixer to my powered studio monitors... Horrible, just horrible. If you want to lose a lot of your signal and have to turn everything up to max to get to low-medium volume out of your speakers, this is the product for you. Returned mine for refund. Plus it was almost [$] bux, ridiculous.
