How to Wire a 70 Volt Commercial Speaker Sound System

[@gabrielnagy4039]

Hi there and thank you for your videos, my question is, I have 10 toa pc-1869 ceiling speakers and I want to install them in the patio ceiling, now I have a Sony STR-DG510, can I wire them to this avr or do I need a 70/100V amplifier. Thank you for your time .

Hi Gabriel, I do not see that the TOA PC-1869 speakers have an 8-ohm bypass, so you would need to use a 70-volt amplifier. Unfortunately, the Sony STR-DG510 receiver does not have 70-volt outputs, so you'll need to source a 70-volt amplifier. We offer several 70V mixer amplifier options that might work with your setup.

Thanks for your video!! Was hoping you would've spoken to speakers with only 2 terminals as opposed to the 4 terminals speakers in your example. My assumption is that I simply go with with a red lead in and out of the same positive terminals and a black wire out and then in of the negative terminal. Just not sure as this is my first 70Volt system. Thanks for any guidance brother!

You're absolutely correct! For a speaker with 2 terminals in a 70V system, you would run the red (positive) wire into the positive terminal of the speaker, and then out of that same terminal to the next speaker. The same goes for the black (negative) wire, connecting it to the negative terminal.

What is the requirement on the speaker i will use, do i need to put 70v matching transformer for 10watts speaker in parallel connection?

[@pureresonanceaudio]

Most 70V speakers come with a built-in transformer, allowing you to select the appropriate tap setting for your needs. You’ll usually find a dial or a series of color-coded wire leads for this purpose. If you have a traditional 8-ohm speaker without a built-in transformer, you can add a 70V matching transformer. However, it’s recommended to have a trained professional or electrician handle the installation to ensure everything is set up correctly and safely.

What are the chances the red marker ran out of ink?

[@pureresonanceaudio]

Haha, busted! The red marker fought the good fight, but it just couldn't keep up. Guess it's time to buy stock in red markers! 😆

Do you need to add the wattage of the volume controls to the amp just like the speakers?

[@pureresonanceaudio]

Hi Jonathan, Great question! No, the volume control only needs enough watts to handle the number of speakers you are going to connect to it. For example, if you wanted to control 4 speakers tapped at 5 watts each (total of 20 watts) you could use our 50-watt volume control. However, if you had 12 speakers at 5 watts (total of 60 watts) you would need our 100-watt volume control. You can check out our options here: www.pureresonanceaudio.com/collections/volume-controls

If I had 6 volume controls Do I daisy chain them first?

[@pureresonanceaudio]

Hi there, Yes you would need to daisy chain your volume controls first.
