By using the GROUND switch, you can 
interrupt (LIFT) the grounding between 
the input and output. Depending on 
how other devices connected to your 
DI-box are grounded, ground loops can 
be eliminated.
◊  Never connect pin 2 or pin 3 to pin 1! 
Never remove the screen protection 
on pin 1. Otherwise, you won’t be able 
to run the DI20 on phantom power 
(for example, phantom power from a 
mixing console).
Battery compartment

Fig. 3.1: Guitar ➠ DI-box ➠ guitar amp/mixing console
This illustration shows the standard 
application of a DI-box. The signal is fed 
unbalanced to a guitar amp and balanced to a 
mixing console (LINK mode). This application 
has advantages when used with bass guitars, 
because very few microphones are able to 
pick up low frequencies at high levels.
