Direct boxes are for sending unbalanced line level audio, for example from a synthesizer, drum machine, sampler, or tape machine from the stage to the FOH mixer. Since unbalanced signals can only be run around 20 feet without degrading (picking up noise, AM radio) they must be balanced. This sends the unbalanced audio signal via a 1/4 inch input into a transformer and then out through an XLR connector where cable run can be a maximum of 820 ft. This is the same type of connector that is used on microphones. From there it can be run into the XLR input on a mixer. This signal comes in at mic level so it will not overload the channel.
