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.
