The Realm of 70 Volt Commercial Sound Speakers includes in ceiling and
ceiling tile loudspeakers, indoor/outdoor, rock & in ground loudspeakers,
wall mount & horns. To function, 70v Commercial Loudspeakers must have transformers
mounted on them to be used. Here at GIN We carry a full line of 70 Volt Speakers
that already have a transformer mounted to them. Conversely, you can also buy
transformers and connect them to regular 8 ohm speakers to make them 70v. The
in line transformers that are used in Commercial Sound Systems are step-down
transformers that convert the high-voltage/low-current coming from the power
amplifier mixer to the low-voltage/high-current signal that makes the loudspeakers
work. Each transformer usually has multiple wattage taps so that each commercial
loud speaker can be individually set as to how much wattage will enter, because
of this, how loud each will be.
With a set up as such, one does not have to worry about keeping the impedance matched throughout their music 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 loudspeakers to one power amp the impedance will change to dangerous levels and potentially destroy the amplifier. However, these you can wire in parallel because of the transformers spoke of earlier, which regulate the wattage. To calculate the wattage of the amp needed to run your system, simply take the total wattage of all the taps include a 20%, just to be safe. Moreover, all the taps do not need to be set at the same watts, hence, you can thereby set the volume for different locations when the amp is at one constant volume.
