70 Volt Distribution Systems, or 70v distributed Audio, is a perfect manner
in which to distribute music or voice audio to multiple locations without having
to worry about the impedance, or resistance, issues one has when dealing with
8 Ohm systems. Hence, 70 Volt Distribution Systems can send distributed audio
to loudspeakers, or horns, to many, dozens, of locations without having to deal
with overload and hence possible fire trouble, which makes them perfect for
Commercial Audio and PA/Public Address applications. To begin with, a 70v System
is comprised of amplifiers, speakers (with in
line transformers), volume controls, and a telephone system interface, depending
on your phone company set up. These 70v systems begin with an Amplifier. GIN
Caries a full line of strait Commercial Audio Power Amplifiers with features
such as volume controls, bass and treble controls, etc., that are built into
the amp to make it a one stop solution. Most commercial amplifiers have speaker
outputs for 4/8/16 ohms, 25 & 70 Volts.
With Commercial Audio as such, one does not have to worry about keeping the impedance matched throughout their audio system as they would on an 8 ohm based system. Impedance is a measure of resistance and in a 8 ohm system if you hook up too many speakers to one amp the impedance will change to dangerous levels and potentially destroy the amplifier. However, here you wire the speakers in parallel with transformers, which regulate the wattage going into each of the speakers. To calculate the wattage of the amp needed to run your system, simply take the total wattage of all the taps on your speakers and include a 20% buffer, just to be safe. Moreover, all the taps do not need to be set at the same wattage, hence, you can thereby set the volume for different speakers when the amp is at one constant volume.
