These 70 Volt Commercial Sound Audio Systems, and PA Public Address Paging Systems, are comprised of 70v Mixer Power Amps, speakers (with in line transformers), volume controls or attenuators, and a telephone system interface, depending on your phone company set up. GIN Caries a full line of Power Amplifiers with features such as volume controls, bass and treble controls, etc., that are built into the commercial audio amplifier to make it a one stop solution. Most Mixer Power Amps have speaker outputs for 4/8/16 ohms, 25 & 70 volt.
With Commercial Sound , Music and Voice Audio, 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 or horns to one amp the impedance will change to dangerous levels and potentially destroy the amplifier. However, with 70 v, you wire the speakers in parallel with in line transformers, which regulate the wattage going into each of the loudspeakers. 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 watts, hence, you can thereby set different volume for different loud speakers when the amplifier is at one constant volume.
