A 70 volt Commercial Audio system is comprised of 70v Amp or amplifier, 70 volt
speakers (with transformers), 70v volume controls or attenuators, and a telephone
system interface, depending on your phone company set up. 70 volt Amps are mostly
used in commercial audio applications or PA Public Address systems. GIN Caries
a full line of strait 70v Amps or Amplifiers with features such as volume controls,
bass and treble controls, etc., that are built into the unit to make it a one
stop solution. Most of these have speaker outputs for 4/8/16 ohms, 25 &
70 volt. .
With a commercial audio 70v Amp, 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, with 70 volt system, you wire the speakers in parallel with transformers, which regulate the wattage going into each of the speakers. To calculate the wattage 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 the different volume for speakers at different locations when the system is at one constant volume.

We began selling over the internet in the year 2000. In the huge world of the internet, a little unknown company like GIN Electronics is easily lost. Hence, we treat our customers with great respect and give them great customer service and thus we have been getting many customers by word of mouth from our satisfied customers.
