Conexiones, Terminales de Entrada de HF | QSC Audio SC-412 specification

Conexiones

El HF-75 tiene terminales de tornillo de barra protectora que aceptan alambre trenzado de calibre de hasta #10 AWG para altavoces.

Terminales de ENTRADA de HF

Conecte la señal de salida del amplificador en los terminales de ENTRADA de HF del altavoz. Observe la polaridad adecuada; ampli- ficador + señal al altavoz + ENTRADA de HF, amplificador - señal al altavoz - ENTRADA de HF. Use el alambre de calibre más grande y de longitud más corta para la aplicación.

¡NOTA! Mantenga la polaridad adecuada en la conexión del altavoz en todo el sistema para obtener el máx- imo rendimiento. ¡No aplique una señal de intervalo total al HF-75! No hay cruce en el HF-75, sólo una red de compensación/demora. Todo el procesamiento de señales requerido debe hacerse antes del HF-75.

Terminales de SALIDA de HF

Los terminales de SALIDA de HF se conectan en fábrica al excitador de compresión. Estos terminales SÓLO se deben conectar al excitador de compresión del HF-75.
