PRO6 Live Audio System
Owner’s Manual
Chapter 2: PRO6 Live Audio System
The PRO6 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.
Despite its compact size the standard PRO6 offers 56 channel inputs, eight auxiliary
returns, 41 buses (16 auxes, 16 matrices, three masters and six solos), eight on-board
effects processors, PEQs (four-band on inputs and six-band on outputs), eight standard
(up to 36 maximum) 31-band GEQs, eight configurable stereo effects

, 5.1 surround
panning and comprehensive, easy-to-use routing. PRO6 automation provides up to
1,000 scenes with snapshot save/recall capability and global edit, and show file
archiving.
The PRO6 Control Centre forms the core of the PRO6 Live Audio System, which also
includes two 19” rack units — a DL351 Modular I/O (7U) and a DL371 Audio System
Engine (7U) — 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. The PRO6 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 PRO6 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 PRO6 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 PRO6 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.
In the standard system configuration (see Figure 4 “Standard system configuration” on
page 29) the main hardware components include:
• PRO6 Control Centre.
• DL351 Modular I/O.
• DL371 Audio System Engine.
• Snakes and mains cables etc.
For information on the DL351 Modular I/O and DL371 Audio System Engine, see
Appendix I "Documentation" on page 373.

centre (plus one stereo effect).
