SOUND

REINFORCEMENT

This 8” mid-range transducer has been designed for P.A. vocal and sound systems applications. It reproduces the mid- frequency range with excellent efficiency and extended frequency response, due to the edgewound aluminium ribbon voice coil, and the massive powerful magnet.

Este altavoz de 8” diseñado específicamente como reproductor de frecuencias medias en aplicaciones profesionales, se caracteriza por una excelente eficiencia, extensa respuesta en frecuencia y potencia admisible importante. Incluye una bobina de 1”1/2 con hilo rectangular de aluminio y un potente sistema magnético.

NOTES

*The power capacity corresponds to the RMS maximum value that can dissipate the loudspeaker when a sinus signal is applied for a period of at least two hours.

Program power is defined as the transducer’s ability to handle normal music program material.

** T-S parameters are measured after an exercise period using a preconditioning power test, using a velocity-current laser transducer, and will reflect the long term parameters, once the loudspeaker has been working for a short period of time.

NOTAS

*La potencia admisible corresponde a la máxima potencia RMS que puede disipar el altavoz durante al menos dos horas, cuando se le aplica una señal senoidal determinada.

Por potencia programa se entiende la capacidad del altavoz en el manejo de señales transitorias, como sería el proporcionado por el contenido de un pasaje musical normal.

* *Los parámetros T-S han sido medidos después de un periodo de fatiga y estabilización de las suspensiones, mediante transductor laser de velocidad-corriente, y son el reflejo de los parámetros a largo plazo del altavoz, una vez éste haya sido instalado y haya trabajado en un corto espacio de tiempo.
