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.

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.
