DI20 : Lots of features in a small box.

This DI box is great. It has all the buttons and connectors on the front which are clearly labelled. The DI box its self has very little sound colouration and would be great for most scenarios. The XLR connections are strong, but the jack connection come across as a compromise.

Con 1

The battery compartment has a screw to change the battery. This means it is kept secure. But is also a pain to change if the battery dies.

This isn't the end of the world, but means you always have to has a screwdriver handy if you need to change it.

Con 2

This DI box also doesn't like long XLR runs to it with phantom power. If you run this from phantom power, you need to have under 20 meters otherwise it won't be reliable. The power loss in the cable will mean it won't have enough power for the big transients in an audio signal.
