DescriptionThis two-day course presents a logical, intuitive, and practical approach to sound system design and integration. It begins with

a refresher course on audio fundamentals. Next, an overview of system design best practices will include loudspeaker selection

and placement, amplifier matching, and system performance optimization with digital signal processing – DSP. At the end of

this course, you will be able to assess the performance of your audio system design for acceptable speech intelligibility and

music clarity.

AudienceThis program is designed for technical individuals who want to grow of their knowledge in audio systems and strengthen their

understanding of system design and integration in real-world scenarios. This includes AV System Design Engineers, Installers, and

Junior AV Consultants.

Bring Your Own LaptopEach student is required to bring a laptop for system design exercises, DSP configuration, and final system validation. Laptops

used in this course must meet or exceed the following hardware and software requirements:

• Intel® Core™2 Duo or equivalent processor

• Microsoft® Windows® 7, Windows 8, or Windows 8.1

• Microsoft .NET Framework 2.0 and 4.0 Full

• A network connection with a data transfer rate of 10 Mbps, 100 Mbps/1000 Mbps recommended

• Adobe Reader

• DSP Configurator software - Ensure that you have the latest version of DSP Configurator software installed prior to attending

this course. This software is available on the Extron Web site.

The Practical Audio in AV Applications Course Covers the Following Topics:

Audio Principles

Most sound problems are the result of overlooking basic

fundamentals. This refresher course covers essential

audio concepts and core principles, and strengthens your

understanding of audio terminology. By seeing how the theory

is used, you will be able to more effectively put it into practice.

The Audio Chain

The key to understanding sound systems is to understand the

signal chain. It is the most common denominator. This course

is built around common components found in a typical sound

system. After this course you will be able to:

• Explain the audio signal flow throughout the audio system

• Understand how audio components work and interface

together

• Properly design an audio system where its components are

used to their fullest potential

Designing Audio Systems in Typical AV Applications

This session includes project-based exercises where you walk

through the functional scope of work for an application. Next,

you will follow a step-by-step guided design session in order

to complete the design. After completing this course you will

learn:

• The Do’s and the Don’ts in applying microphone

techniques, and how to address comb filtering

• System design and performance optimization using a

DSP-based solution

• Fundamentals of loudspeaker selection and placement

based on achieving acceptable speech intelligibility

• Design basics necessary to determine the target SPL,

loudspeakers density, and power requirements

Practical Approach to Commissioning

In this session, you will use your laptop and Extron

DSP Configurator software to set up the DSP configuration that

is required for the project. With this practical exercise you will:

• Learn why proper gain structure is needed

• Apply the four essential steps to setting up proper gain

structure for AV systems

• Use Extron Building Blocks to help minimize configuration

time

This exercise concludes with validating your DSP configuration

using the pre-installed system in the classroom. This will enable

you to test or check your design and make final adjustments if

necessary.

Instrumentation and Troubleshooting

This session focuses on many of the common audio problems

in the field. It provides you with a “divide and conquer”

approach to tackle problems like “Hum and Buzz,” and reveals

practical tips for fixing acoustic feedback.

Digital Audio Networks

This session is designed to offer a

comprehensive introduction to digital

audio networks. It will dramatically shorten your learning curve

for understanding the Dante digital audio network, how it is

applied, and where it is deployed.
