Whirlwind Direct4 Direct Box The DIRECT4 combines features found on four of Whirlwind's DIRECTOR direct boxes in one unit. Perfect for converting unbalanced signals from multiple i nstruments, keys, acoustic guitar preamps, CD and tape players, computer sound cards, etc. The input and output grounds of each section are isolated from each other. This allows the DIRECT4 to be used as if it were four completely separate DIs without fear of creating ground loop interaction.
