    Chapter 1: Introduction The DL431 Mic Splitter is a six-unit (6U) high 19” rack unit that provides 24 mic/line inputs. Each input feeds three separate preamps, two of which have separate remote and local gain controls, while the third has fixed gain. The two preamps with gain controls feed separate analogue to digital (A/D) converters, which pass digital audio to the network.

    Appendix A: Application Notes Using the 30Hz filter The DL431 Mic Splitter’s 30Hz filter is an analogue high pass filter (HPF). It is a very low frequency signal filter with a 30Hz corner frequency and 12dB per octave Butterworth roll off. This filter can be switched into circuit following the mic amp to make better use of the analogue-to-digital (A/D) conversion headroom by removing the very low frequency audio content.

  • Page 53: System Interconnections

    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).

  • Page 54: Foh And Mon

    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.

  • Page 55: Mix Matrix

    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.

  • Page 60: Resilience To Failure (Redundancy)

    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.
