Cuando desea operar con altavoces a una distancia superior a
los 50 metros del amplificador, es recomendable la instalación
de transformadores de línea para prevenir las pérdidas de nivel.
Este método se conoce como distribución de tensión constante
y elimina el cálculo de impedancias de carga e instalaciones
serie-paralelo. Con este sistema todos los altavoces se
conectan en paralelo.
Esta salida de tensión constante distribuye la potencia entre los
altavoces. Cada uno de ellos debe disponer de un transformador
de línea de 100 V el cual marca la potencia deseada al
altavoz.
El número total de potencia soportada por los altavoces debe ser
la misma que la potencia de salida del amplificador o menor.
