The "Soundcraft STANDARD STAGEBOX 6" is part of the modular digital input/output system designed for the Vi Series of large-format digital consoles. The '6' in the name does not refer to the number of channels, but rather the Vi6 console it was initially paired with. The stagebox is a 9U rack-mountable unit that comes in a standard configuration of 64 microphone/line inputs and 32 analog line outputs, although it can be customized with various optional I/O cards. It is designed for maximum reliability, featuring dual redundant power supplies and rugged Cat5 or optical MADI connections to the console. The stagebox remotely controls key analog functions, including mic preamp gain and phantom power, directly from the console.
