The PB12 is a passive 1 line level input, 12 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 twelve 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): 11" x 5.5" x 2"

Also available with 6 or 24 outputs.

Specifications:

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