viii Safety Precautions
XL8 Control Centre
Quick Reference Guide
Power
THE XL8 SYSTEM COMPONENTS SHOULD NEVER BE OPERATED WITH THE
MAINS EARTH DISCONNECTED!
Please note that the system power supplies contain LETHAL VOLTAGES greatly in
excess of the mains voltage and that its rails can produce extremely large currents that
could burn out equipment and wiring if shorted. All testing and servicing must ONLY be
carried out by approved service engineers.
This apparatus should only be operated with the power supply connected to ground via
the ground in the mains connector.
The internal power supplies are of the switch mode type that automatically sense the
incoming mains voltage and will work where the nominal voltage is in the range
100VAC to 240VAC.
Two PowerCon® mains inlets are provided on the rear panel. The correct leads for
connection in the area to which the unit was shipped are supplied with the unit. The
equipment should only be plugged into the mains outlets using the supplied leads.
We strongly recommend that, for safety and to optimise the life and performance of the
equipment, the mains cable plugs are removed from the power outlets when the
equipment is not to be used for extended periods of time or during electrical storms.
When removing the equipment’s electric plugs from the outlets, always hold the plug
itself and not the cable. Pulling out the plug by the cable can damage it.
Never insert or remove an electric plug with wet hands.
Do not insert or remove a PowerCon® connector into/from the rear of control centre
with mains power and any of the mains bay switches on. Y ou must make sure all mains
bay switches are off and mains is switched off at the power outlet(s) first.
When switching the five bay mains on/off switches on or off please make sure it is done
one at a time. It is important that you don’t switch on or off two or more
simultaneously.
Before switching the XL8 on or off, please make sure that all monitor loudspeaker
power amplifiers are turned off or muted.
Handling the equipment
Completely isolate the equipment electrically and disconnect all cables from the
equipment before moving it.
When lifting or moving the equipment, always take its size and weight into
consideration. If necessary, use suitable lifting equipment or transporting gear, or
sufficient additional personnel.
Do not insert your fingers or hand in any gaps or openings on the equipment, for
example, vents.
Avoid inserting or dropping foreign objects, such as paper, plastic, metal etc., into any
gaps or openings on the equipment, for example, vents. If this happens, immediately
disconnect the equipment from the AC mains; see “Safety warnings” on page vii. Then
have the equipment inspected by the manufacturer's qualified service personnel.
Do not press or rub on the sensitive surface of the GUI screens.
If the glass of the GUI screen is broken, liquid crystals shouldn’t leak through the break
due to the surface tension of the thin layer and the type of construction of the LCD
panel. However, in the unlikely event that you do make contact with this substance,
please wash it out with soap.

XL8 Control Centre
Quick Reference Guide
Chapter 1: Introduction
The XL8 Control Centre is a user-friendly, state-of-the-art, high performance digital
console that forms an integral part of the XL8 Live Performance System, which has
been specifically designed for live use.
The XL8 Control Centre comprises a combined control surface and graphical user
interface (GUI) that provide an array of easy-to-use controls for precise manipulation of
audio. The control surface has been designed to emulate the fast access of an analogue
control surface by presenting things in a familiar, consistent and logical way so that
experienced analogue engineers can migrate easily to the new digital surface. This is
enhanced by visual representations on the GUI at the top of control surface, which also
provides extra functionality.
About this guide
This quick reference guide shows you how to connect up an XL8 Live Performance
System, switch on the XL8 Control Centre and then quickly familiarises you with its
basic operation in order to produce some audio.
For full details on connecting and setting up, operation, servicing etc., please refer to
the XL8 Control Centre Operator Manual, part number DOC02-XL8, which is available at
www.midasconsoles.com.

Quick Reference Guide
XL8 Live Performance System overview
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 sound environment.
The XL8 Control Centre forms the core of the XL8 Live Performance System, which also
includes a number of 19” rack modules that are interconnected by a networked data
system. The network carries both proprietary control data and open architecture
AES50 digital audio, and uses readily available standard cabling and connectors.
Along with the XL8 Control Centre, there are four mic splitters, five I/O units, 10 DSP
units, two routers and a Klark Teknik DN9331 RAPIDE that, between them, form the
standard XL8 Live Performance System configuration.
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 a identical redundant spare that is ready to take over should it fail.
Other failure scenarios are managed by the N+1 principle, where redundant
components form an acceptable fraction of the system, for example, one of the DSP
units in the rack is a redundant spare.
Control centre
The XL8 Control Centre is built on a robust Midas steel frame chassis similar to those
used for established Midas analogue products. The frame houses five bays, each of
which is a discrete hardware module that can operate independently of its neighbour.
Collectively, the bays provide the primary mixing needs of the engineer.
Each bay has its own power supply, control surface modules, control surface
processors, GUI processor and GUI screen. The control surface and GUI processors for
each bay are separately connected to the network on duplicated Ethernet links. Also
housed within each bay are dual redundant master control processors and dual
redundant high-speed network routers (eight AES50 connections each).
The control surface of the XL8 Control Centre is populated with instantly recognisable
controls that are logically distributed in major sections, so that all the controls you need
to access most of the time are always on the control surface, while the remainder are
only one action away. All I/O meters are permanently on display, both on the control
surface and the GUI (if configured), to give instant monitoring feedback. The layout
also allows two operators to work on the XL8 Control Centre simultaneously.
The principle of XL8 Control Centre operation is based on the concept of colours and
groups rather than ‘layering’ or ‘paging’, which is the case with most digital consoles on
the market today. With so many channels available it is far easier to remember them
by their group colour and name rather than by their channel number.
Multiple hardware faults are tolerated by the XL8 Control Centre without loss of audio
control due to the dual redundancy and N+1 methods incorporated in the system. This
is further helped by the modular nature of the bays and GUI independence. So if a
whole bay fails, others can take over or be used instead, and any of the GUI screens
can be used to operate the whole XL8 Control Centre, even if none of the control
surface hardware is working.

Bays
The XL8 control centre has five bays, of which there are three types:
• Input Bays (3-off): Provide fast access to large numbers of faders and important
input signal processing controls. The bays are numbered 1, 2 and 3, in order from
left to right.
• Mix Bay: Gives fast access to large numbers of creative mix faders.
• Output Bay: Gives access to the matrix/master output mixes and monitor faders,
the automation central control and large quantities of complex signal processing
systems.
Each bay has a GUI screen at the top and a control surface below, which is subdivided
into a control area (shallow rake) and a flat (horizontal) area at the bottom that
contains faders, navigation zones, automation etc.

Control surface layout
The diagram below shows the main control surface areas of the five bays.
• A - input fast zone: contains operator’s ‘must have now’ controls in eight input
fast strips.
• B - input channel strip: provides a more comprehensive control by allowing
detailed adjustments to a single channel’s audio parameters; contains D-zone
(dynamic parameters) and E-zone (EQ parameters).
•
C - input navigation zone: for input GUI navigation via glide pad, and input
channel selection using an array of keys.
•
D - mix fast zone: auxiliary (aux) mix masters in eight dual-channel mix fast
strips.
•
E - output channel strip: provides a more comprehensive control by allowing
detailed adjustments to a single channel’s audio parameters.
•
F - VCA and POP groups: VCA and POP group select buttons and VCA faders.
•
G - output fast zone: output (matrix) mix masters in eight dual-channel output
fast strips, and also stereo (left and right) and mono masters.
• H - monitors: A and B signal path monitoring, communications and mute groups.
•
I - I-zone: operator-assignable effects controls.
•
J - automation: scene store/recall and system edit.
•
K - primary navigation zone: for mix bay and output bay GUI screen navigation
via trackballs, and screen access panel for quick access to certain GUI screen menu
options.
