Mackie MDB Series, USB Signal Direct Box (MDB-USB)

Quality is really good. All connections work well and the sound is good. Great value.

Works as intended, sounds great, lightweight.

Great DI, this thing has been a trooper for years

I work for a local vintage theater that is being remodeled and one of the issues was a ground loop problem when connecting multiple audio mixers across multiple circuits. This stereo passive box worked great, just be aware that you will lose a little amplification as it drops the signal to line level.

I have a very elaborate modular synth set up that goes through a Pioneer DJM V10 which unfortunately only has unbalanced RCA inputs. I route the master to a Motu M4 audio interface with Mogami XLRs but there was so much noise due to the unbalanced RCAs. For the price point, you really can’t beat it (especially compared to JDIs). Highly recommend!!!! Totally cleaned up the noise!

buen producto, funciona super bien

Excellent product its worth the price

I really like this particular model because I don't have to carry around spare batteries. Of course, you are reliant upon your mixer having phantom power, so that is an important limitation to be aware of if you are relying upon other people's boards. But if you are using your own board, this is a cool piece of hardware and has a lot of nice features like the 15db pad, the ability to combine two sources or use the second 1/4" jack as a "through" jack. I also like the ability to switch polarity and the ground lift. In addition, it feels like a solid little box that is well made. I've been using them for about a year now with no issues - just nice quiet signal.
