1.1 Hardware: DI Boxes

DI Boxes

  •  DI boxes (direct input) are used to eliminate the need to mic up electronic instruments.
  • They can be plugged directly in to a mixer or audio interface.
  • They convert an unbalanced (two wire) signal to a balanced (three wire)
  • Microphones usually use XLR connections (Extra Low Resistance).
  • Balanced cables use phase cancellation to reduce noise; they copy and invert the sound signal at both ends then use the resulting signal to cancel out noise.
