Workshop on Introduction to Sound Reinforcement System for Audio Operators

The objective of this workshop is to introduce a hands on experience to audio operators and technician. The knowledge gained from attending this workshop will help them to properly operate and tackle the common problem facing with the majority of sound reinforcement system.

What You Will Learn:

  • The inner workings of audio interfaces,such as line signal, Low and high impedance signal, power and other signal characteristics. 
  • Understand the different type of microphone.
  • Understand microphone technique
  • Understand microphone characteristics such as frequency responses.
  • Understand loudspeaker cables and the required size (AWG)
  • Understand system gain structure for optimum signal to noise ratio.
  • How to match audio power amplifier to the loudspeaker.
  • Basic Troubleshooting on typical Audio System
  • Understand the The functionality of a typical audio power amplifier.
  • Understand the operational and mixing technique of a typical professional audio mixer.
  • An equalization strategy that gets at what you can fix, and avoids "over equalizing" the sound system.
  • How to properly setup PA system.
  • and many more.
This three days workshop covers the theory and practical aspect of operating the sound reinforcement system. The whole workshop will be conducted side by side with typical live working sound system so they can relate the theory being taught and the actual application. It include a hands on session where the technician can demonstrate what have been taught.

Instructor Profile:

C.G. Simon

He is currently works as a senior broadcast Engineer with the local Audio Consultancy and Engineering Company. He has accumulated suffice knowledge in sound engineering while working fulltime as broadcast engineer. With his 18 years of working experience ranging from setting up and running pro-audio sound system, troubleshooting and designing system pertaining to broadcasting, he is well suited to conduct the said workshop.

He graduated from University of East London, United Kingdom with Bachelor Engineering in Electrical and Electronic (Honours Degree). He has always been actively involved with music and shown keen interest in Sound reinforcement System ever since his school days. He is also a musician and played the guitar, keyboard and drums.

To further improve his teaching skills, he attended numerous local and overseas training courses, seminars and workshop and this help to update his technical knowledge. He has also undergone a “Train the Trainers” program as well as a “Training Needs Analysis” Course. He is a qualified trainer and able to analyze the technical training requirement of department personnel if necessary.

If you setup a radio station, your FM transmitter should be tested before even trying to use it with an antenna. 

Tuning or testing of a FM transmitter requires the use of a dummy load. This prevents unwanted radiation during test (antenna is in active) and tune procedure. This is to ensure the FM transmitter output stage is always correctly loaded. 

We recommended two dummy loads rated at 60W and 1500W respectively. 60W version is suitable for smaller transmitters. Where else, the 1500W version is for medium to big transmitters.

Features 60W Dummy Load:
- Gold Plated PL Connector
- 0 - 600 MHz Range 50 Ohms

Features Palstar DL1500 1.5kW HF Dummy Load :
- Enables Short Term Off Air Testing Up To 1500 Watts For Frequencies Up To 500 MHz
- Dimensions: 2.75" H x 3.5" W x 8" D
- Weight: 1.5 lbs
- Hyperbolic tuning cone
-Impedance: 54 Ohms +/- 5%

Understanding the Audio Mixer

In audio business world, it is a fact that audio engineering is a combination of both science and art. It dependency of each other can not be denied. In the context of an audio mixer, understanding what's under the hood of the mixer is paramount important. By understanding the science part it will help you to develop your art side. There are many ways to learn how audio mixer operate but nothing can compare if you attend an audio workshop where you can gained a whole lot more about mixers than you'd learn from a typical owner's manual, including:
  • Names and functions of the major building blocks of a mixer
  • How to read and follow a block diagram
  • Signal paths through the mixer
  • Function of all the controls and some special features
  • Hookup diagrams for many different applications
  • Mixing and operating tips
ACE is organizing many workshop and seminar to help you have better understanding of an audio system particularly concerning the science part.
