For instruments with onboard preamps, keyboards or CD players.
The PDI double-shielded D.I. box provides increased protection against noise and interference. Features 1/4" high impedance from instrument wired in the panel. Makes no difference which is used for input or output. 1/4" high impedance goes to your amp when input/output is used as a loop.
Balanced and floating low-impedance XLR goes to your workstation or mixing console, and ignores +48V phantom power. The Lift mode severs ground connection between the input and the XLR output and ground remains connected in GND mode.
