1 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 (see figure on page 11) . Due to
the balanced connection to the mixer, in-
terference can be avoided even when long
connection cables are used . If hum loops
occur, the ground connection between
the instrument and the mixer can be inter-
rupted by means of the ground lift switch .
High signal levels can be reduced by
OUTPU
means of the attenuator and matched to
BA
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 (e . g . guitar amplifier or
tube amplifier) on the sound will be main-
tained at the mixer input .
