The PPB20 Press Patch Box from Palmer is an audio signal distributor that features separate inputs for microphone and line signals. An input amplifier with a transformer-balanced input provides a wide and dynamic range to this Press Patch Box. It has a total of 20 transformer-balanced XLR/M outputs with separate paired driver circuits for connecting video cameras and recording equipment. There is a nominal output level of +4 dBu at 600 Ohms and channels 19 and 20 have phono sockets and TRS jack sockets for balanced/unbalanced signals.
When more than 20 outputs are required, additional Press Patch Boxes can be connected to the rear bus in/out socket. Signal monitoring is provided by an adjustable headphone amplifier and a 10 LED strip displaying a range of -40 to +10 dB. There is an integrated shielded power supply unit and an extra DC input allows you to connect the Press Patch Box to a battery source as well. The box is constructed of sheet steel with a powder-coated surface for strength and durability.
