Description
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.
