The PB24 is a passive 1 line level input distributed to 24 mic. level output press box   The PB Series expands mic outputs when used with line outs on PRESSPOWER2 or PRESSMITE active press boxes or any time a line level feed is available.

These passive units distribute one line level input to twenty-four mic level outputs*. Each output is transformer isolated, provides excellent interchannel isolation and is ground lifted to help eliminate noise problems. Whirlwind TRSP-2F transformers are used throughout. (*Line level signal MUST be provided into this passive press box. A microphone directly into the input will not provide enough signal level for proper operation.)

The boxes are constructed with rugged, cold-rolled steel. Dimensions (L x W x D): 9.5" x 11.25" x 2"

 Also available with 6 or 12 outputs. (pictured above on either side of the larger PB24)


  • Input Impedance: 2k Ohms
  • Output Impedance: 150 Ohms
  • Operating Level: 0dB input = -43dB output
  • Channel-to-channel Isolation: 65dB between verticallyadjacent channelpairs, 107 dB between non-vertically adjacent pairs
