BOX Series


  • .2 channel high impedance direct inputs for electronic musical instrument signal feed.
  • .The ¼" TRS LINK socket carries a parallel-wired direct feed from the input.
  • .Selectable 3 steps attenuator for Hi-Z direct input.
  • .Accept power from plug-in 9V battery or +20V to +48V phantom power.
  • .2 channel XLR Balanced Low-Z output with isolation transformer.


The Unika DI-BOX2 is a 2 channels active direct box, it is very easy to use, simply plug it in, turn on the power and it goes to work. However, there are a number of features built in that should be understood in order to get the most out of the DI-BOX2.
