BCU7.1

The analog bass management system BCU7.1 is used in addition to our BASIS models and is employed everywhere, where source systems don‘t provide a separate bass mangement system, e.g. in outside broadcasting vans our small post production studios. The BCU7.1 is geared for application with active subwoofers from the BASIS series and provide enough flexibility for optimal adjustment to the application site without being confronted with a complicated control concept. The bass management system applies all tasks of filtering, equalisation, level adjustment of the subwoofer as well as bass signal limiting. It is connected via a special XLR4 cable to the MPI (Multipurpose Input) of the actual BASIS model. Because of a compact cabinet it is easily integrated into existing setups. In contrast to other alternatives, where the bass management system is integrated into the subwoofer, with BCU7.1 wiring effort is significantly reduced.
