Precautions

Before installing, setting up or operating this equipment make sure you have read and
fully understand all of this section and the “IMPORTANT SAFETY INSTRUCTIONS” at the
front of this document.

This equipment is supplied by a mains voltage that can cause electric shock injury!
The following must be observed in order to maintain safety and electromagnetic compatibility (EMC)

performance.

Safety warnings

Signal 0V is connected internally to the
chassis.

To completely isolate this equipment from
the AC mains, while observing full safety
precautions (see “Power”), switch off the
isolator switch (above the mains power
sockets on rear of control centre) and then
switch off the mains at the three mains
outlets. Unplug the three mains leads from
the rear of the control centre.

To avoid electrical shock do not remove
covers.

General precautions

In the event of ground loop problems,
disconnect the signal screen at one end of the
connecting cables. Note that this can only be
done when the equipment is used within a
balanced system.

Do not remove, hide or deface any warnings or
cautions.

Power

The power supplies contain LETHAL VOLTAGES
greatly in excess of the mains voltage and its
rails can produce extremely large currents that
could burn out equipment and wiring if shorted.

distributed so as to meet local safety
regulations.

A Volex locking type plug is fitted on each
supplied mains cable, which plugs into a mains
IEC connector on the equipment. When fitted
properly the Volex plug locks into place,
preventing it from working loose, or being
inadvertently knocked loose or pulled out. To fit
a Volex plug, insert it into the mains IEC
connector and push it in until it locks in place.
Then, check to make sure it is locked in place.
To remove it, release its locking device and then
pull it out. When fitting or removing a Volex
plug, always hold the plug itself and never use
the cable, as this may damage it.

During operation of the control centre, a
minimum of two of its three mains inlets must
be connected and supplying power.

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 connect/disconnect a mains power
connector to/from the control centre while
power is being applied to it. Switch the power
off first.

Before switching the control centre on or off,
make sure that all monitor loudspeaker power
amplifiers are turned off or muted.

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.

Each mains inlet is to be sourced from its own
separate wall-mounted mains outlet socket.
Otherwise, their mains sources must be suitably

Overview

A PRO3 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, whose features include:

• Dual ‘daylight visible’ screens with three-way KVM switch.

•XL8-style ‘fast zones’.

• XL8-style dual operator ‘channel strips’.

• 10 VCAs.

• Six POPulation groups.

•Configurable ‘area B’.

• Surround panning, including 5.1, quad and left-centre-right-surround (LCRS).

• Dual redundant Linux control computers.

• Three AES50 ports on the rear of control centre for I/O expansion and XL8

• Eight AES50 ports for stage end of snake for I/O expansion.

• Up to 24 configurable inputs and 24 configurable outputs on control centre

• N+1 redundant, hot-swappable triple power supplies.

• Three-year factory warran ty.

• Accessories include: Klark Teknik DN9331 Rapide Graphic Controller, Klark Teknik

connectivity.

(depending on type of I/O cards fitted).

DN9696 Recorder and Klark Teknik DN9650 Network Bridge.

Despite its compact size the standard PRO3 offers 48 channel inputs, eight auxiliary
returns, 33 buses (16 auxes, eight matrices, three masters and six solos), six on-board
effects processors, PEQs (four-band on inputs and six-band on outputs), eight standard

PRO3 Control Centre
Quick Reference Guide

6 Chapter 2: PRO3 Live Audio System

(up to 28 maximum) 31-band GEQs, eight configurable stereo effects, 5.1 surround
panning and comprehensive, easy-to-use routing. PRO3 automation provides up to
1,000 scenes with snapshot save/recall capability and global edit, and show file
archiving.

The PRO3 Control Centre forms the core of the PRO3 Live Audio System, which also
includes two 19” rack units — a DL251 Audio System I/O (5U) and a DL371 Audio
System Engine (7U) — 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. The PRO3 uses a proven stable
Linux operating system. All of the control centre’s internal and network routing
(“patching”) is managed via the graphical user interface (GUI).

Operation of the control surface is intuitive, unique and easy. Its layout is based on
familiar analogue lines to retain that ‘analogue’ feel. To manage the numerous
channels, the control centre utilises VCA/POP groups and colours, and additionally there
are various navigational controls that aid quick channel/bus access and selection. A
daylight-viewable GUI at the top of the control surface assists operation and provides
extra functionality.

The live audio system is tolerant of many types of hardware or software failure. 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. Other failure
scenarios are managed by the N+1 principle, where redundant components form an
acceptable fraction of the system.

The Klark Teknik DN9696 Recorder can be used with the live audio system for live
multi-track recording and ‘virtual’ sound check. Optional equipment includes the XL8’s
DL451 I/O and DL431 splitter, and the DN9331 RapidE for remote GEQ operation.

Applications

The PRO Series are the ‘work horse’ mid- to high-end Midas Digital Console Systems,
akin to the ‘industry standard’ Heritage 3000. Although the PRO Series are designed
for the traditional touring live sound environment, they are also ideal for medium- sized
theatre, small house of worship installations and broadcast. So, being a truly
multi-functional console in the Midas tradition, the PRO Series are suitable for many
applications, such as:

• Live sound touring MON or FOH duties.

• Live sound small theatre MON or FOH duties.

• Live sound house of worship MON or FOH duties.

• Live sound broadcast mixer with basic 5.1 surround capabilities and monitoring.

Chapter 3: About The Control Centre

This chapter introduces you to the control centre and provides a brief hardware
description.

Overview of the control centre

The control centre has a combined control surface and GUI that provide an array of
easy-to-use controls for the precise manipulation of audio.

The control centre is of modular construction and is built on a robust Midas steel frame
chassis similar to those used for established Midas analogue products. The frame
houses three full size bays with a smaller one on the right. All of the bays are
controlled from a single processor and, collectively, provide the primary mixing needs
of the engineer.

All associated power supplies, computer motherboards, memory, graphics cards etc.
are housed within the control centre, which also contains a digital audio router box that
supports local FOH (insert) I/O connectors on the rear panel. Substantial forced
air-cooling is provided by a bulkhead and large (but slow moving) internal fans. These
produce very low noise, suitable for seated areas theatres and concert sound.

Typical control centre

Externally, the control centre has three main areas: control surface, GUI and rear
panel. The control surface is populated with instantly recognisable controls that are
logically distributed in major sections. The GUI, which comprises two screens at the top
of the centre bays, enhances operation by providing visual representations of the
control surface and also gives you extra functionality. The rear panel provides all of the
control centre and network connectivity, and houses the mains power sockets and
isolator switch.

Being of modular design, the overall form and shape of the control centre is similar to
Midas’ flagship XL8. The control surface is split into bays, each one containing a flat
fader tray and shallow raked control area. The centre bays also have a third area that
houses a steep-raked display screen.

Multiple hardware fault types are tolerated by the 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. Either of

the GUI screens can be used to operate the whole control centre, even if none of the
control surface hardware is working. The unit offers the facility of universal input, N+1
redundant power supplies with three latching mains connectors.

Bay and GUI layout

The control centre has four discrete bays that house the following control surface
controls:

• Input bays (12-channel and 4-channel) — two input bays provide fast access to
input faders and important signal processing controls.

• Mix bay — provides access to outputs and groups, a detailed processing controller
(all channels) and navigational controls.

• Master bay — provides access to the master output mixes, monitor (A and B)
faders, automation, comms control, assignable effects control, and another set of
detailed processing and navigational controls.

Figure 1: Bay and GUI layout

T wo GUI display screens at the top of the central bays pro vide extensive screen support
(standard configuration) and extra functionality for the channels and buses. For
example, when mixing or processing. They also facilitate the use of the GUI menu,
which gives you access to the many powerful features of the control centre, such as
patching, effects, GEQs, diagnostics etc.
