The Whirlwind PB24 passive press box distributes one line level input to twenty-four mic level outputs*. Each output of the Whirlwind PB24 is transformer isolated, provides excellent interchannel isolation and is ground lifted to help eliminate noise problems. Whirlwind TRSP-2F transformers are used throughout the Whirlwind PB12.

The Whirlwind PB24 is an output expander for use with Whirwind's PRESSPOWER2 and PRESSMITE active press box line outputs, or any other live press conference or forum application where a line level feed is available.

The Whirlwind PB24 is a professional product in a moderate price range, intended for broadcast and commercial conferencing applications.

The Whirlwind PB24 is constructed with rugged, cold-rolled steel.

(*) Line level signal MUST be provided into the Whirlwind PB24 passive press box. A microphone directly into the input will not provide enough signal level for proper operation.
