PSC Press TrainThe Professional Sound Corporation Press Train is a one input, 12 output passive audio distribution box designed for press conference. This ruggedly built device can be used in conjunction with our PSC Press Bridge or with any professional balanced line level source. Its input accepts a standard +4dBm balanced line level signal and provides 12 transformer isolated microphone level outputs. Our custom wound, mu-metal-shielded transformer's high input impedance insure that up to 10 PSC Press Train can be connected to any professional 600 ohm balanced line without excessive line loading or distortion. Thus, you can obtain 120 separate, transformer-isolated, microphone level outputs from a signal line level source. In addition, the PSC Press Train includes a high quality Sifam V.U meter for level setting and monitoring purposes.The PSC Press Train has one line level input and two line level loop-through connectors that are used to feed additional Press Trains. Up to 10 Press Trains may be connected in any daisy chain configuration without loss of sound quality. Interconnection of additional PSC Press Trains is accomplished with standard microphone cables. Each of the Press Trains' 12 isolated microphone level outputs have isolated grounds to eliminate ground loops.Specifications:Size: 10.50 inches x 3.40 inches x 3.10 inches (24cm x 9 cm x 8 cm)Weight: 3 lbs ( 1.4 Kg)Input : Balanced +4dB 12K Ohm ImpedanceOutput: Balanced -4dB 150 Ohm ImpedanceCase: AluminumFinish: Black Powder CoatWarranty: 1 year limited
