The Procab MSB20.4 is a professional multicore stage box designed to handle a larger number of microphone and line-level signals on a stage or in a studio and route them to a mixer. It functions as a solid and reliable distribution box, eliminating the need for a myriad of individual cables from the stage to the mixer, which simplifies setup and reduces cable clutter. The stage box is constructed from robust metal, ensuring the necessary durability for demanding use in live sound productions, rental environments, and permanent installations. As standard, Procab stage boxes come with the necessary XLR connectors and often a suitable carrying bag for transport and protection.
