The Whirlwind DIR Studio or PA Direct Box converts an unbalanced line, instrument or speaker level signal to low impedance balanced microphone level, which is then suitable for imputing to a console or microphone preamp. The unit is a passive device and therefore requires no external power supply. The unit features a ground lift switch and a 30-dB pad for selecting between line/instrument or speaker level signals.
