A transformer steps up the output of the system's amplifier to the distribution voltage. At the distant loudspeaker locations, a step-down transformer matches the speaker to the rated voltage of the line, so the speaker produces rated nominal output when the line is at nominal voltage.
Transformers with various taps allow the installer to adjust the sound pressure level up or down at an individual loudspeaker. Purpose-built models are available that have the transformer contained within the loudspeaker enclosure. The loudspeaker step-down transformer primary is connected in parallel to the constant-voltage line. [3]
Transformers are used to change AC voltage levels, such transformers being termed step-up or step-down type to increase or decrease voltage level, respectively. Transformers can also be used to provide galvanic isolation between circuits as well as to couple stages of signal-processing circuits.
Transformers step down transmission voltages, 35 kV or more, down to primary distribution voltages. These are medium voltage circuits, usually 600–35 000 V. [1] From the transformer, power goes to the busbar that can split the distribution power off in multiple directions. The bus distributes power to distribution lines, which fan out to ...
A transformer or autotransformer can be used; (auto)transformers are inherently reversible, so the same transformer can be used to step the voltage up, or step it down by the same ratio. Lighter and smaller devices can be made using electronic circuitry; reducing the voltage electronically is simpler and cheaper than increasing it.
What is voltage? “ Voltage is one of the basic ways to classify an electrical system,” White said. You could think of it as being similar to “pressure” in a water system, he said. “High ...
