For use in distributing 1 line level input to multiple mic level outputs such a s broadcast media feeds. Each output is transformer isolated and ground lifted to eliminate interference between outputs. TRSP-2 transformers are used throughout. Available with 6, 12 or 24 outputs. Input Impedance: 2Kohms; Output Impedance: 150ohms; Operating Level: 0dB input = -45dB output; Channel to Channel Isolation: 65dB; Output noise: -103dB. 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.
