- These passive units distribute one line level input to multiple 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.
Note: Line level signal MUST be provided into these passive press boxes. A microphone directly into the input will not provide enough signal level for proper operation.
The PB Series expands mic outputs when used with line outs on PRESSPOWER 2 or PRESSMITE active press boxes or any time a line level feed is available.
