About 70 Volt Ceiling Speakers, including in ceiling, indoor/outdoor (which
can be mounted there), and tile models. To function in a 70v system, the speakers
must have transformers mounted on them to be used. The transformers have wattage
taps on them that dictates the wattage (or how loud) that each speaker will play.
Here at GIN We carry a full line of 70 Volt Ceiling Speakers that already have
a transformer mounted to them. As stated, Conversely, you can also buy transformers
and connect them to regular 8 ohm speakers to make them 70v. The transformers
that are used are step-down transformers that convert the high-voltage/low-current
coming from the amplifier to the low-voltage/high-current signal that makes the
speaker work. Each transformer usually has multiple wattage taps so that each
unit can be individually set as to how much wattage will enter, because of this,
how loud each ceiling speaker 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 speakers to one amp the impedance will change to dangerous levels and potentially
destroy the amplifier. However, you can wire these in parallel because of the
transformers spoke of earlier, which again regulates the wattage. To calculate
the wattage of the 70 volt amp needed to run your system, simply take the total
wattage of all the taps 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 location when the amp is at one constant volume.
