The PB-8 press box is perfect for press conferences or any situation requiring a single mic signal to be "split" multiple times. Its features include a rugged steel box, a single XLR female mic level source input, a "loop" output (to go to a mixing console to interface with an external phantom power supply, or to "daisy chain" this unit to a second PB-8 for additional isolated outputs), and eight discrete isolated XLR male outputs. Due to the D.C. blocking characteristics of a transformer, the isolated outputs will not pass phantom power. The connectors are recessed to resist damage.
