The DIRECT2 is a two channel, passive direct box from Whirlwind that converts unbalanced line, instrument or speaker level signals to low impedance balanced microphone levels, which are then suitable for imputing to a console or microphone preamp.
The unit is a passive device and therefore requires no external power supply. Each channel features a ground lift switch and a 20dB pad for selecting between line/instrument or speaker level signals.
The input and output grounds of each section are isolated from each other. This allows the DIRECT2 to be used as if it were two completely separate DIs without fear of creating ground loop interaction.
