Boss DI-1 Boss DI-1 Overview: Boss DI-1 Direct Box The DI-1 is a high-quality direct box with crystal-clear sound for transforming high-impedance, unbalanced instrument outputs to the low-impedance, balanced inputs of a mixing console. This versatile box facilitates connection of the high-impedance, unbalanced output from your instrument into the low-impedance, balanced input of a mixing console. Along with its balanced low impedance XLR output, two separate high impedance loop-through outputs are offered—one that's parallel wired off of the input jack, and one that's buffered to prevent your guitar from combining the D.I. and guitar amp signals. The XLR output offers a Ground (pin 1) Lift Switch that comes in handy for combating hums, buzzes and other ground loop-induced problems. A Phase switch selects whether pin 2 or 3 is hot, making the DI-1 potentially compatible with any mixer, regardless of wiring configuration. The DI-1 can be powered either from an internal 9V battery or phantom power supply. The unit's convenient power-conservation mode extends battery life.
