The Press Train from PSC is a compact, one-input and twelve-output passive audio distribution box designed to deliver multiple audio feeds for press conferences. The single XLR input accepts a standard +4 dBm balanced line-level signal and outputs twelve, transformer-isolated microphone-level outputs. The unit is built to survive its intended use and is housed in a waterproof Pelican 1120 case for ease of shipping.
All the outputs have isolated grounds to eliminate ground loops. The input transformer is custom wound, mu-metal-shielded, and its high input impedance ensures that up to eight Press Trains can be connected to any professional 600Ω balanced line without excessive line loading or distortion. Using the two line-level loop-through connectors can yield up to ninety-six separate, transformer-isolated, microphone-level outputs from a single line-level source.
Up to three-hundred outputs can be created using the company's Press Bridge and twenty-four Press Trains, without loss of sound quality. Interconnection of additional PSC Press Trains is accomplished using standard microphone cables.
