Single Source, Single Zone
These systems distribute the same audio source everywhere—individual rooms must listen to the same audio source. This is the most simple type of system that can be installed. If designed properly, no special equipment is required other than one amplifier and a desired audio source. Care must be taken not to overload the amplifier by keeping the total speaker impedance above the amplifier's rated minimum impedance. This can be done by wiring the speakers in series, as opposed to parallel (though if the impedance is too high, power transfer is inefficient), with impedance-matching transformers, or by using constant-voltage transformers (often, 70 volts). These systems are commonly employed in retail environments and large buildings such as churches, where large, open areas benefit from additional speakers.

Famous quotes containing the words single and/or zone:
“A writer is in danger of allowing his talent to dull who lets more than a year go past without finding himself in his rightful place of composition, the small single unluxurious “retreat” of the twentieth century, the hotel bedroom.”
—Cyril Connolly (1903–1974)
“There was a continuous movement now, from Zone Five to Zone Four. And from Zone Four to Zone Three, and from us, up the pass. There was a lightness, a freshness, and an enquiry and a remaking and an inspiration where there had been only stagnation. And closed frontiers. For this is how we all see it now.”
—Doris Lessing (b. 1919)
