Whirlwind PB12 Passive Press Box with 1 Line Input and 1 Mic Output
for Broadcast and Business Conference Applications
The Whirlwind PB12 passive unit distributes 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. The box is constructed with rugged, cold-rolled steel.
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.
