Controles de Ganancia

Los controles de ganancia están empotrados y se pueden ajustar con un destornillador pequeño o con una herramienta plana. Si se desea, se puede instalar la cubierta de seguridad del control de ganancia para evitar que se hagan cambios a los ajustes del instalador.

Gire hacia la derecha los controles de ganancia para aumentar la ganancia y hacia la izquierda para reducir la ganancia. La ganancia de máximo voltaje del amplificador varía dependiendo de la designación del modelo. La ganancia de máximo voltaje para cada modelo se muestra en la etiqueta del panel frontal entre paréntesis, junto al ajuste de atenuación de 0dB.

Los controles de ganancia están marcados en dB de atenuación. Hay 21 retenes para ajustes repetibles. Los 14 pasos superiores son de aproximadamente 1 dB cada uno, y normalmente los ajustes deben hacerse dentro de este intervalo. El intervalo menor de -14 dB no se debe usar para los niveles normales del programa, ya que se podría exceder el espacio libre de entrada, pero se puede usar para hacer pruebas a niveles reducidos. En el ajuste mínimo, la señal se corta completamente.

Controles de ganancia en modelos de 2 canales. Las marcas variarán dependiendo del modelo.

Controles de ganancia en modelos de 4 canales. Las marcas variarán dependiendo del modelo.

Placa de Seguridad del Control de Ganancia

La cubierta bloquea el acceso a los ajustes de ganancia. Los indicadores LED aún están visibles para supervisar la operación del sistema.

1. Use un destornillador hexagonal de 9/64" o de 3.5 mm

para aflojar el tornillo varias vueltas. No lo saque completamente.

2.Deslice el extremo derecho de la cubierta debajo del tornillo aflojado.

3.Introduzca las lengüetas terminales izquierdas en la última fila de ranuras de ventilación, y deslice el panel completamente hacia la derecha. Se deben fijar en las ranuras.

4.Confirme que los LED sean visibles a través de la cubierta. Apriete cuidadosamente el tornillo hexagonal.
