PA 70v Audio System
Professional grade audio system for your whole farm or themed attraction at a do-it-yourself price
- The Amplifier You start with a professional grade 70v amplifier that offers 240 watts of power
- The Speaker Wire You'll need something to connect the amp to your speakers. We sell a high quality stranded, direct burial speaker wire which is built for a permanent installation. If you don't use our wire, we highly recommend you use at least an 18 gauge stranded wire
- The Speakers Adding speakers is the final piece of the puzzle. Determine how many you require by the area you're covering. Large outdoor areas require the larger 6.5" or 8" speakers, whereas the smaller 5.25" shine indoors.
Using Google Maps is a great way to plan speaker placement along with how much wire you'll need. Click above photos to enlarge
Speakers in a 70v system can be wired in any configuration. You can daisey-chain them together, or jump from one speaker to another. Your only limit is how much speaker wire you can fit into a terminal!
How far up should I mount my speakers?We recommend mounting speakers at least 12' high. They can be mounted lower, but should never be lower than 7'.
How long can a run of speaker wire be before I lose volume or quality?There are many factors that effect the power loss from the source (amplifier) to the speaker, however to see any noticeable drop-off in volume, your installation would have to be miles long. A single speaker connected to the amplifier can have a wire run of 2,000' before noticing any substantial volume drop. The more speakers that are on a single line, the more the volume will drop off at the speakers at the end of the line. You can combat that by lowering the wattage taps on the speakers closer to the amplifier, and turning the wattage taps higher on the speakers near the end of the line. For the vast majority of our customers, power drop-off due to wire length will never be a worry.
Will I hear an echo from speakers across my property?The only echo you will hear is from the time it takes sound to travel through the air. Unlike traditional audio set-ups, audio will leave the speakers of a 70v system at the same time even across great distances. This is why high voltage systems are used at large venues like Theme Parks and sports stadiums. Although it will take time for the sound to travel through the air, your message will play on all of the speakers over your property at the same time.
How many speakers can I use on one amplifier?We use a 240 watt, 70v amplifier to power our PA Audio Systems. That means you have 240 watts of power to play with. Each speaker we sell has their own 70v transformer tap on them, which sets the wattage the speaker will use (and will also increase or decrease their volume). Using 6.5" speakers as an example, at their maximum setting of 40 watts, you can use a total of 6 speakers on one amplifier. If you set them one step down at 20 watts, you can then use 12 speakers on one amplifier; however, the speakers will operate at a lower volume.
What are these speaker taps you keep talking about?Simply put, the speaker tap, or 70v transformer tap, is a setting on the speaker that determines how much power it will receive. A speaker mounted right next to a jump pillow doesn't need to be as loud as a speaker covering audio over a corn maze. So setting the tap on the jump pillow speaker lower, while setting the corn maze speaker higher is one way of controlling your audio levels.
