  • Page 53: Pro6 Live Audio System

    Appendix F: PRO6 Live Audio System This chapter provides a detailed overview of the XL8 Live Performance System. Standard system configuration The PRO6 Live Audio System is a very powerful and flexible audio processing system that provides a complete solution for any audio mixing and signal distribution application in a live sound environment.
  • Page 54 • Mic amps — High quality, overload tolerant microphone amplifier per input. • Dynamics — High quality dynamic processing with traditional analogue artefacts. Midas dynamics has four styles on the inputs and five on the outputs. • EQ — Fully interpolated phase shifting EQ for that “Midas” sound.

  • Page 55: Applications

    US, UK and Singapore. Applications The PRO6 is the ‘work horse’ mid- to high-end Midas Digital Console System, akin to the ‘industry standard’ Heritage 3000. Although the PRO6 is designed for the traditional touring live sound environment, it is also ideal for medium-sized theatre, small house of worship installations and broadcast.

  • Page 56: System Components (Standard Supply)

    Appendix F: PRO6 Live Audio System System components (standard supply) The PRO6 Live Audio System is modular, allowing for some variations in physical placement and system size. The standard PRO6 touring system package is configured as a 14U rack (containing two DL3n1 units) in a single, easily portable flight case, with an equally portable, flight-cased control surface and minimal cabling.

  • Page 57: Mix Matrix

    Mix matrix • 16-off matrix buses, routable from the 56 inputs and eight aux inputs, and 16 aux buses and three master buses. • 16-off aux buses, routable from the 56 inputs and eight aux inputs. All the bus routings (above) provide simultaneous and time aligned mixing of all the sources, which will be defeatable for minimum latency requirements.

  • Page 58: Processing

    Appendix F: PRO6 Live Audio System Processing Although the control centre system allows for considerable insertion of external processing it also embodies more than enough internal high quality processing to eliminate the need for this, in the interests of simplicity and reduced overall system size, weight and cost.
