the Mbox
Mbox provides two input types (DI and Line)
that correspond to the different signal strengths
output by different types of instruments.
DI Input Instruments such as electric guitar or

output than line level instruments use the DI
(“Direct Inject”) input.
Line Input Line level devices, including elec-
tronic audio sources such as mixers, samplers,
keyboards, and synthesizers use the Line input.
