100v line vs low impedance - What's the difference?

Inter-M Stand: 3/A35

The HowToAV team catches up with AVIXA audio expert, @madsoundguy himself - Chuck Espinoza - to talk about 100v line and low impedance audio. What's the difference, how do they compare and how to calculate speaker loads, etc. We caught up with Chuck during ISE 2019 on the AVIXA booth. We take a look at how 100v / 70v line audio is used for commercial applications such as public address and background music, whereas low impedance audio is used for professional music, live performance and home entertainment music systems. And what's the difference between 70v, 100v line, high & low impedance, constant voltage etc?
