70 V Sound System Myths - Prosoundtraining
https://www.prosoundtraining.com/2016/06/23/ten-70-v-system-myths/
The 70.7 volt system gets its name from the RMS (think average) voltage of a pure tone (a sine wave) whose peak voltage is 100 V, which is the highest voltage that, by code, can be present on the line. So, feed a sine wave into the system and turn it up until the “70 V” amplifier clips, and you will read 70 Vrms on the line, which is 100 Vpeak.

2) A 70-volt system allows you to run more speakers off a single amplifier. 3) A 70-volt system plays in mono, not stereo, so speaker placement is not as critical. 4) A 70-volt system allows you to daisy chain speakers together, running the wire from one speaker to the next as opposed to home runs back to the amplifier for each 8-ohm speaker. 5) A 70-volt system allows you to …

First, you need to buy an amplifier that has a 70-volt output. These are commercial-grade products so you won't find one at a hi-fi or home theater store. The second thing is that you will need to buy a special transformer for every speaker running off this system. The picture below was provided by Parts Express.

How To Design A Basic Commercial Sound System
http://erictraining.com/articles/AV/how_to_design%2070%20volt.pdf
Commercial sound systems are also referred to as 70-Volt Distributed Sound Systems. In a 70-Volt Distributed Sound System, a transformer is included with each speaker. This changes the system from low impedance (4 or 8 ohm) to high impedance and allows con-nection of a greater number of speakers in parallel to the amplifier. A commercial grade amplifier provides a higher …
