Is 70V low voltage?
In some jurisdictions, a 70V system is considered to be “high voltage” and therefore can require conduit, but that is not a standard across all jurisdictions in the United States so once again it is important to know the regulations in the areas you work!
Can 70V speakers be wired in parallel?
With a 70V system you can hang hundreds of speakers in parallel on a single amplifier output if you provide a matching load. Details of impedance matching are covered later. In addition, a 70V distributed system is relatively easy to design, and allows flexibility in power settings.
Can I use 8 ohm speakers on a 70V AMP?
Any amp that can produce 600 watts into 8 ohms is considered to be a direct drive for 70V lines. By doing it that way- you don’t have all the problems associated with an output transformer that large.
How many speakers can you have on a 70v AMP?
For example, with a 180 watt / 70 volt amplifier, you can install speakers that total close to 150 watts. It does not matter if it is 10 speakers that are 15 watts each or 25 speakers that are tapped at 5 watts each.
Can I use a 70V Amp with 8 ohm speakers?
In fact you do not need a a step up transformer to get the 70V level. Any amp that can produce 600 watts into 8 ohms is considered to be a direct drive for 70V lines.
How many watts is a 70V speaker?
Connect the same speakers to the 70 Volt line terminals of the same 120 watt amplifier and the amplifier will only see a load of 100 Watts. Example 2: The total watts of all the (70 Volt) speakers totals 50 Watts.
How many speakers can I put on a 70v system?
Can you use a 70v speaker with a regular amp?
Yes. All you need is an amp that will drive the load and has sufficient voltage swing. There will still be transformers at each speaker.
Can a transformer be used as an audio amplifier?
No, you cannot use a “power” transformer as a “audio” transformer. A power transformer handles low frequency – 50 or 60 Hz. An audio transformer will need to handle frequencies from about 40 Hz to about 20 KHz.
Can you use 8ohm amp on 70V speakers?
As long as the amp has enough voltage swing (as stated 600 watts @8 ohms) it will be just fine. You also eliminate the issue of transformers on the output(very low impedance at low freq among others).
What is a 70 volt amplifier?
The 70v amplifier will take an audio signal and turn it into a wattage like an electrical signal which will then drive your speakers. 70-volt technology allows us to take multiple speakers and run one individual line at a fixed wattage and a constant voltage.
