DL452 digital I/O module DL452 digital I/O module The DL452 digital I/O module provides four (stereo) AES/EBU inputs and outputs. Its rear panel houses these I/Os in four pairs. Each input has a check and a sync LED and each output has a check and a mute LED. Each AES/EBU input can run at sample rates up to 96kHz (44.1Hz, 48kHz, 88.2kHz and 96kHz) using a sample rate converter (SRC).
Appendix D: Replacing An I/O Module This appendix provides instructions on replacing an module on the rear panel of the DL451 Modular I/O. Replacing a module The design of the DL451 Modular I/O makes module replacement very easy and straightforward. The unit has rack guides in each of the three module positions so that the modules can slide easily in and out.

Appendix E: Service Information This appendix gives you servicing information for your unit. If you are in any doubt or have queries about any of the procedures in this appendix, contact Midas Technical Support. Contact details can be found at the front of this manual.
Appendix E: Service Information Equipment disposal When this equipment has come to the end of it useful life, its disposal may come under the DIRECTIVE 2002/96/EC OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL of 27 January 2003 on waste electrical and electronic equipment (WEEE). Hazardous substances in WEEE contaminate water, soil and air and ultimately put at risk our environment and health.
Appendix F: 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. The standard XL8 system offers 96 channel inputs, 51 outputs, 51 buses (32 auxes/groups, 16 matrices and three masters), 16 on-board effects processors, PEQs (four-band on inputs and six-band on outputs), up to 48 assignable GEQs (if all stereo effects units are being used), 16 configurable stereo effects (from eight options),...
Page 56
Appendix F: 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). •...

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 •...
Appendix F: 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.
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).
Appendix F: 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 42. Figure 4 on page 49 shows in more detail the interconnections between each unit in a typical XL8 Live Performance System FOH and MON set up.
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.
Appendix F: 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. •...
Appendix F: 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).
Surround capabilities 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. •...
Appendix F: 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.

Integration of third party software 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.

Appendix G: Setting Up An XL8 System Outboard equipment racks To ensure the correct installation and function of the outboard equipment, such as the DL4n1 units and DN9696 recorder, the racks must meet the following general requirements. • Shock mounting (for non-installation environments): The racks must provide adequate shock protection of the units they house by incorporating appropriately- designed shock protection methods, for example, a foam-suspended rack or a frame suspended on anti-vibration mounts etc.
Wiring instructions Stage rack 2 Stage rack 2, also known as the “DL461/DL471 engine rack”, contains the two routers and 10 DSP units. Important: In general, the physical location of the hardware units within each rack is not critical, and alternative configurations are acceptable for different packaging preferences.
