3 Applications

The DI Box (Direct Injection) allows for op-
timal connection of a musical instrument
with a high-impedance, unbalanced out-
put to a low-impedance, balanced input of
a mixer (fig . 2) . By means of the balanced
connection to the mixer, interference can
be avoided even when long connection
cables are used . If hum loops occur, the
ground connection between instrument
and mixer can be separated by means of
the groundlift switch; the devices will be
galvanically isolated .
High signal levels can be reduced by
means of the attenuator and matched to
the mixer input . Thus, the DI Box can also
be connected directly to the speaker out-
put of an instrument amplifier; the effect
of the amplifier on the sound (e . g . guitar
amplifier or tube amplifier) will be main-
tained at the mixer input .
4 Setting the DI Box into
Operation
The DI Box does not need any power sup-
ply . In the text below, only channel A is
described . Proceed in the same way to set
channel B into operation .
