|IMPEDANCE IN AUDIO TECHNOLOGY by Marty McCann Several years ago
I wrote four separate articles on Loudspeaker Impedance that
were published in various Peavey Monitor Magazines. Realizing
that many people may not have read each of the articles, I have
decided to address the subject of Impedance in audio once again.
This will be a detailed technical paper that will start out with
the basics so that sound system operators and technicians may
have an opportunity to establish a thorough understanding of the
fundamental concepts of loudspeaker impedance and their
applications. I will also continue to address the subject of
impedance as it applies to the interfacing of those electronic
components ahead of the power amplifier. In order to completely
understand the workings of impedance, one must grasp the
mathematical aspects of impedance and Ohm's Law. Ohm's Law is
actually quite simple. However, some people get glassy eyed when
it comes to any kind of mathematics. If you want be just a
roadie in the music industry
