As a relatively new volunteer sound engineer at church, one of the biggest obstacles I have faced in live mixing is understanding the basic concepts of EQ and how to adequately use all the EQ controls on our live mixer to create an atmosphere that is conducive to worship. In the EQ Master Class, David Mills does an outstanding job explaining all these things using straight forward language and examples, and provides sample files to practice with. Since I have purchased this class, I have watched it several times and now feel like I have a much better understanding of what frequency is, where individual instruments sit on the tonal spectrum, and how to use the EQ tools to get the sounds that I desire. I would highly recommend this class to anyone who is looking to improve their skills as a sound engineer at church or at home. I am looking forward to continuing on in my training by purchasing the Master Class in Compression.
