Features

Front Panel

1. Power Switch: Press this switch to power DN-474A on or off.

2. Level Knobs: Turn these knobs to set the output level for each channel.

3. Signal/Clip/Protection LEDs: These lights will illuminate different colors to show the signal status of each channel input:

• Signal LED: The input’s Signal LED will be lit green when it is receiving a signal at an optimal level.

• Clip LED: The input’s Clip LED is “peaking” when the LED is lit red (higher than 0 dB). Turn its Level knob counter-clockwise or reduce the volume of the source to prevent “clipping” (distortion).

• Protection LED: If the Protection LED turns red, the unit is in heat protection mode and will not output sound. To restore sound output, reduce the temperature by making sure there is good ventilation and by decreasing the signal level.

4. Air Intake Vents: Keep the vents clear from obstructions to allow air to flow through the front grill for proper performance.

Rear Panel

1. Power Inlet: Use the included power cable to connect this input to a power outlet.

2. Fuse: If the unit’s fuse is broken, lift this tab to replace the fuse. Replace it with a fuse with

an appropriate rating. Using a fuse with an incorrect rating can damage the unit and/or fuse.

3. Inputs: Use Euroblock connectors to connect these channel inputs to your audio sources.

Each channel has a ground (G), cold/negative (–), and hot/positive (+) connector. Make sure the wiring of each device matches each connection.

4. Outputs: Use Euroblock connectors to connect these channel outputs to your

loudspeakers. Make sure the wiring of each loudspeaker is done properly for each output.

5. Operation Mode Switch: Select the operation mode to 70V or 100V for Outputs 3 and 4

by moving the dip-switches to the desired position.

6. Exhaust Vents: Air from the front intake flows through the unit and exits here. For proper

performance, do not block the air vent.

Características

Panel frontal

1. Interruptor de encendido: Pulse este interruptor para encender o apagar el DN-474A.

2. Perilla de nivel: Gire estas perillas para ajustar el nivel de salida de cada canal.

3. LED de señal/clip: Estas luces se encenderán con diferentes colores para mostrar el estado de

la señal de cada entrada de canal:

• LED de señal: El LED de señal de la entrada se encenderá de verde cuando esté recibiendo una señal con el nivel óptimo.

• LED de recorte: El LED de recorte llega a su "pico" cuando el LED se enciende de rojo (más de 0 dB). Gire su perilla Level (Nivel) en sentido antihorario o disminuya el volumen de la fuente para evitar el "recorte" (distorsión).

• LED de protección: Si el LED de protección se enciende de rojo, la unidad se encuentra en modo de protección y no emitirá sonido. Para restaurar la salida de sonido, reduzca la temperatura asegurándose de que haya una buena ventilación y disminuyendo el nivel de la señal.

4. Ventilaciones de entrada de aire: Mantenga las ventilaciones libres de obstrucciones para permitir que el aire fluya a través de la rejilla delantera asegurando así un buen funcionamiento.

Panel trasero

1. Entrada de corriente: Utilice el cable de corriente incluido para conectar esta entrada a una toma de corriente.

2. Fusible: Si el fusible de la unidad está roto, levante esta lengüeta para reemplazar el fusible. Reemplácelo por un fusible con especificación apropiada. Si utiliza un fusible de especificación incorrecta, puede dañarse la unidad y/o el fusible.

3. Entradas: Utilice conectores Euroblock para conectar estas entradas de canal a sus fuentes de audio. Cada entrada tiene un conector a tierra (G), un conector frío/negativo (–), y un conector caliente/positivo (+). Asegúrese de que el cableado de cada dispositivo coincida con cada conexión.

4. Salidas: Utilice conectores Euroblock para conectar estas salidas de canal a sus altavoces. Asegúrese de que el cableado de cada altavoz sea el correcto para cada salida.

5. Interruptor de modo de operación: Seleccione el modo de operación a 70 V o 100 V para salidas 3 y 4 del canal moviendo los interruptores dip a la posición deseada.

6. Ventilaciones de escape: El aire que proviene desde las entradas delanteras fluye por la unidad y sale por aquí. Para obtener un mejor funcionamiento, no obstruya esta salida de aire.
