Overview

Blue Sky International has created the BMC to offer full bass management and remote volume control in a convenient, easy to use and affordable package. Designed for professional applications, such as surround sound control or post production, the Blue Sky BMC features fully balanced inputs and outputs, along with ultra high-quality audio components. The BMC can be combined with Sky System One, ProDesk or the Big Blue mid-field monitor to create a world class multi-channel studio monitoring system.
