ProDesk: 5.1 System, (5) Sat 5.25, (1) Sub 8, and Bass Management Controller MK II

In professional applications such as video post, ProDesk™ is the first truly full-range 5.1 monitoring system specifically designed for critical mixing and monitoring on the desktop. ProDesk™ brings the desktop user the same spectral performance as the larger Blue Sky systems, with the only compromise being less output.

The bass management for a 5.1 system is incorporated within Blue Sky’s Bass Management Controller (BMC), which also provides calibration and level control. Additionally, two BMC's can be combined to expand a ProDesk 5.1 system, all the way up to 10.2 channels of audio.

Application Notes

A ProDesk™ 5.1 system is designed for use in professional desktop music and audio production applications using computers and digital audio workstations, including audio editing, film, video and broadcast post production. Because of the many variables associated with room acoustics, independent subwoofer and satellite level controls are provided. These allow the user to adjust the level of the sats and sub to achieve seamless full-range response, from below 30Hz to beyond 20kHz.

Bass Management Controller MK II

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 music 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 or the soon to be released ProDesk System to create a world class multi-channel studio monitoring system. Because the BMC utilizes industry standard bass management circuitry it is also compatible with many other studio monitors. The BMC includes all the functions you need for proper bass management and multi-channel volume control.
