Introduction

In the previous Module A lessons, you learned how to identify, describe and apply the operations of an audio mixer. Now in Module B, you will identify describe and apply the operations of the microphone that include the use some of the audio mixer parts. The audio mixer is an integral part of the broadcast studio and used in most of its processes. Therefore, the audio mixer’s concepts and process, as part of the overall process, will be reinforced through out all modules in Unit 1.

8


Importance

Knowing the microphone equipment, its parts and operations is important to getting your voice properly into the audio mixer, CD player, open reel recorder and radio waves. Also, microphone’s operation in an integral component in the audio lab’s overall operation.

9


Overview

This lesson will review the concepts of microphone equipment. Then it will review the process of using the microphone to help with any troubleshooting. Finally, the lesson will provide series of procedural steps that result in the application of the microphone’s operation. There are three main pieces of microphone equipment: audio mixer, microphone and speakers. The audio mixer is an integral part of the microphone. So, Module A will be reviewed in the lesson’s beginning to reinforce the audio mixer’s concepts and process. Ending with a evaluation and feedback.

10


ObjectivesGiven an audio mixer, microphone and speakers, LWBAT correctly identify equipment and respective parts used in the operations of the typical microphone. Criteria: five-out-of-seven equipment parts will be identified correctly.

Given a particular problem with sound from the microphone, LWBAT correctly apply process flow information of typical microphone equipment based on how an audio mixer, microphone and speakers properly operate together. Criteria: Two-out-of-three microphone, problematic, case-studies will be answered correctly with multiple choice questions.

Given an audio mixer, microphone and speakers, LWBAT apply the correct steps to create verbal sound thru microphone equipment.

Criteria: Verbal sound thru microphone will stay within range of 80-100% on the VU meter. (cannot measure without equipment)
