The Press Patch Box is a special kind of audio signal distributor intended for use at press conferences. It features separate inputs for microphone and line signals (from a mixing console output).
Also available as stereo version (PPB20S)
A high quality input amplifier with a transformer balanced input provides a wide dynamic range. A total of 20 transformer-balanced XLR/m outputs with separate paired driver circuits make it possible to connect up video cameras and other recording equipment.
The nominal output level is +4 dBu at 600 ohm. Channels 19 and 20 have TRS jack sockets for balanced/unbalanced signals and also phono sockets (-10 dBu nominal level).
Where more than 20 outputs are required, additional PPB 20s can be hooked up via a rear BUS IN/OUT socket. Signal monitoring is provided by a 10 LED strip displaying a range of -40 to +10 dB (0 dB in the display = 4 dBu output) and an adjustable headphones amplifier.
The PPB20 has an integral, shielded power supply unit. An extra DC input makes it possible to connect up a (backup) battery power source. A PW4 can provide the necessary backup power supply for two PPB20s.
