31 Appendix E: XL8 Live Performance System The XL8 Live Performance 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.
32 Appendix E: XL8 Live Performance System Configuration • All outputs have six-band parametric EQ and five-mode compressor styles. • Up to 16 stereo FX units. • Up to 48 assignable GEQs (16 if all 16 stereo FX units are being used). • Control from RAPIDE. Showfiles • USB connectors for show archiving. • Showfiles are both forward and backward compatible. Warranty Three years. Audio quality • Three mic pre amps per input FOH, monitor and broadcast. • Midas EQ (sound quality and ‘feel’).
33 Features User interface - status visibility • Daylight-visible screens. • Metering. • 63 discrete 20-segment LED meters. • Discrete metering for dynamics and direct outputs. • “All the meters all of the time”. • “ST” assign switch. • Eight channels of key data plus single channel strip per input screen. Dual operators - perfect for festival situations • Modular control centre with multiple input areas. • Area A and Area B assignment. • Discrete dual solo systems.
34 Appendix E: XL8 Live Performance System System components (standard supply) The standard XL8 Live Performance System comprises the following equipment: • XL8 Control Centre (1-off): Comprises five discrete, independent bays, each with its own power supply, surface modules, surface processor, GUI processor and GUI screen. The standard five-bay control centre has three bay types, input (3-off), mix (1-off) and output (1-off).
35 System interconnections System interconnections Figure 1 shows basic system interconnectivity and indicates where the XL8 Control Centre (highlighted in red) sits within the system. This figure also illustrates redundancy by showing that the two halves of the system - left and right - are identical (ignoring the DN9331 RAPIDE). The XL8 Control Centre, which forms the core of the XL8 Live Performance System, is directly connected to the local I/O units, DN9331 RAPIDE and routers (via the ‘snake’).
36 Appendix E: XL8 Live Performance System FOH and MON The XL8 Live Performance System can be used as a front of house (FOH) or stage monitor (MON) system. Also, by sharing the four mic splitters, these two types of system can be used in tandem, as shown in Figure 2 on page 36. Figure 4 on page 43 shows in more detail the interconnections between each unit in a typical XL8 Live Performance System FOH and MON set up.
37 Mix matrix Mix matrix Ultimately, the mix matrix defines the XL8 Control Centre’s capability. Probably the best way to imagine the mix matrix is to think of an analogue console layout, where inputs run vertically and buses run horizontally. A mix matrix is usually defined as the number of buses and the quantity of simultaneously-mixable inputs there are per bus. The following diagram illustrates the capability within the control centre.
38 Appendix E: XL8 Live Performance System Each of the 16 auxiliary inputs has: • Input gain. • Source from internal FX or external pool input. • 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 32 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).
Audio physical connections 39 Effects processing and GEQs The XL8 contains 16 mono Klark Teknik (KT) GEQs and 16 effects processors as standard. The 16 effects processors can be freely chosen from: • Delay. • KT DN780 reverb. • Flanger. • Phaser. • Stereo Graphic EQ. • Pitch shifter. • Square ONE Dynamics. • 3-band compressor. The 16 mono KT GEQs can be patched into any output. There are many patching options for the effects processors: • Assign to any insert send/return.
40 Appendix E: XL8 Live Performance System Uses of the configurable audio connections The standard XL8 Live Performance System has a total configurable audio channel count (on the DL451 I/O units) of between 120 and 240, depending on the mix of analogue and digital I/O (excluding the non-configurable 96 mic inputs on the DL431 mic splitter). Typically, the allocation would be: • 16-off mic/line auxiliary inputs (giving a total of 112 mic inputs as standard). • 32-off aux/group bus outputs.
Surround capabilities 41 The maximum count of any one type of connection is: • 96-off input insert sends. • 96-off input insert returns. • 96-off input compressor external side chain connections. • 96-off input noise gate external side chain connections. • 96-off input direct outputs. • 51-off mix bus insert sends. • 51-off mix bus insert returns. • 51-off mix bus direct inputs. • 1-off talk mic input.
42 Appendix E: XL8 Live Performance System All system connections are duplicated for full dual redundancy. Resilience to failure (redundancy) The XL8 Live Performance System is tolerant of any single failure of hardware or software. To achieve this the system employs dual-redundancy, where a key component has an identical redundant spare that is ready to take over should it fail.
43 Resilience to failure (redundancy) Local I/O units Internal bay processor Dual redundant internal master controller XL8 Control Centre Dual redundant internal router Control data Cat6/optical ‘snake’ Audio data N + 1 redundant spare Control and audio data Router Clock sync This diagram gives a more detailed illustration of the interconnections in a standard FOH and stage monitor set up.
44 Appendix E: XL8 Live Performance System Local I/O units Key OK XL8 Control Centre Not active Internal bay processor Internal master controller Internal router DSP units I/O units Router This diagram illustrates an extreme example of dual redundancy in a standard FOH and stage monitor set up, where one half of the system is down. Please note this is a highly unlikely scenario.

46 Appendix E: XL8 Live Performance System Control software The XL8’s operating system 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 software 47 The XL8 Control Centre features a four-way KVM switch on the output module screen, as well as external video IN and OUT for each of the five screens. Control centre views can be routed to external monitors, and external video sources can be displayed on the control centre’s screens. The KVM switch facilitates the control of three external computers from the screen, trackball and keyboard of the control centre.
