37 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.
38 Appendix F: PRO6 Live Audio System Key features Please remember, the PRO6 is not just a console, it’s a LIVE AUDIO SYSTEM! • High channel count — 56 mixed primary inputs (sourced from up to 112 input locations) and 35 output channels. • Control centre — Small and very compact with an exciting but familiar and ergonomic control surface, enhanced by a two-screen GUI. • Performance — Reduced price, scale and features, but still with XL8 audio performance.
39 Applications • Latency — Low and managed latency through the system. Minimal latency and fully time aligned. • Cabling — Cat 5e or fibre optic snakes. Standard system has reduced cabling as compared to any other available solution. • System design and network: • • • Integrated open-architecture AES50 digital audio distribution. • Up to 100 metres (Cat 5e) or up to 500 metres (optical fibre) of dual redundant connectivity between hardware elements.
40 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. This package comprises: • • 1-off PRO6 Control Centre (in a flight case).
41 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.
42 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. Processing components The processing available is: • 56 x 12 or 24dB/oct. high pass filters. • 56 x 6 or 12dB/oct. low pass filters.
43 Processing Each of the eight auxiliary inputs has: • Input gain. • Source from internal FX or external input. • EQ. • Fader. • Panpot (SIS™). • Routing via level controls to the 16 matrix buses. • Routing via pan control to the left, right and mono master buses. Mix channel processing Each of the 16 auxiliary mix buses has: • Subgroup, auxiliary or mix minus modes. • Dual mono or stereo pair modes. • Six-band PEQ. • Optional 31-band GEQ (replaces PEQ).
44 Appendix F: PRO6 Live Audio System • Direct input. • Routing via level controls to 16 matrix buses. Effects processing and GEQs The PRO6 contains eight mono Klark Teknik (KT) GEQs and seven effects processors as standard. The seven effects processors can be freely chosen from: • KT DN780 reverb. • Delay. • Flanger. • Phaser. • Pitch shifter. • SQ1 dynamics. • Stereo 3-band compressor. The eight mono KT GEQs can be patched into any output.
Surround capabilities 45 Surround capabilities Theatres and broadcast have differing requirements for surround and both are catered for in the PRO6. Conventional stereo and SIS™ panning is assignable on a channel by channel basis (channel one can be in stereo while channel two can be in SIS™), as follows: • Stereo left–right routing to master buses. • SIS™ left–right–centre routing to master buses.
46 Appendix F: PRO6 Live Audio System Control software The operating system of the PRO6 is Linux, which is an open-source, stable, proven operating system (OS). Linux is used in many mission-critical applications worldwide and has allowed Midas’ software engineers to write a ground-up system that contains no ‘hidden’ or unused code. This has resulted in an efficient, compact application, which is quick in operation, quick booting and comparatively easy to debug.
Integration of third party hardware/software 47 PC or MAC computers can use the Ethernet tunnel in the MidasNET system, and can communicate with other computers on the network. The PRO6 Control Centre features an external video for both screens, and the master bay GUI screen (on the right) also has a three-way KVM switch. Control centre views can be routed to external monitors, and external video sources can be displayed on the control centre.
