3/9/2019 11:15 - 12:30 p.m. Room: C6

This is a beginner/intermediate course designed for audio operators that have fundamental understanding of sound system but would like to get better. The topic is Microphone and will cover all the types of microphones and direct connection of instruments. Are you going direct with instruments? Let’s find out what microphone is good to use and how to correctly connect the instrument to the sound board. Will cover how to power microphones that need remote power as well as instrument interface that also need to be remotely powered. How to stop the POP’s so you can be ready but not noisy. The main discussion will be microphones and all the different types and how they are meant to be used.

Audio Visual & Media: Maintaining Your Sound Equipment

3/9/2019 12:45 - 2:00 p.m. Room: C6

This is a beginner class on taking care of sound equipment. How to clean a microphone windscreen, testing cables, what is the correct microphone stand to have. Are you using the correct cable to connect instruments into the system? Setting up the microphone and as soon as you step away it falls to the stage. You move the microphone cable to another input and it still does not work… Is the microphone bad? Connector “Life Cycles” or “Mating Cycles” what is this and what does it mean, are the cables just worn out?

Audio Visual & Media: Acoustics

3/3/2018

This is an intermediate course designed for audio operators that are running sound regularly but cannot seem to get the sound to work better. The topic is Acoustics and will cover tools that are available for you to see the sound. Yes there is an app for that. How can you see the sound visually and use that to make changes. What else in the sanctuary is causing interference with the sound? “All I hear is the drums!” Can you fix that and how. Will go over the tools and how they can be used to make changes to the sound when operating and how to measure stuff that is causing interference. Will talk about plexiglass shields and defusesers and more.

Audio Visual & Media: Mix It Up

3/3/2018

This is a beginner/intermediate course that will talk about the heart of the sound system. What to do with all those knobs and what do they do? Bought a new console but cannot get it to work. Is digital better then analog? What types of consoles are there and should you go digital? The mixer has lots of knobs and switches with as much as an acronym next to it, so what does that thing do? Is there one setting that fits all inputs or outputs. Will go over equalizer (EQ) settings and how to use this to make sources sound better and to help curb the squeal sound coming out of the system.

Audio Visual & Media: Garbled Sound

3/3/2018

This is a beginner/intermediate course about the electronics of the sound system and how they are suppose too work together. What happened to the beautiful singer’s voice when they began to use the microphone and all you hear is a Charlie Brown adult voice (Wah wah wah wah)? Do you have big enough speakers to get the sound level you need? Are the amplifiers big enough to get the power to the speakers? Is there proper electrical supply to the equipment so it is not over heating or unable to produce the level of audio that it is rated for? Does the wireless microphone not sound as good as the wired microphone? This will include talking about audio acronyms that describe the electronic signals and how to read them on an app or other test equipment. How to set the levels on everything but the mixing consol.
