Setup

1. Speaker Placement

The center channel speaker is crucial for dialogue clarity in a home theater system. Place the D-509C directly above or below your television or projection screen, centered horizontally. Ensure it is on a stable, flat surface, such as a TV stand or shelf, and positioned at approximately ear level when seated for the best listening experience.

2. Connecting Speaker Cables

Before connecting, ensure your AV receiver or amplifier is turned off and unplugged from the power outlet. Use high-quality speaker cables for optimal sound performance.

  1. Prepare the speaker cables by stripping approximately 1/2 inch (12-15 mm) of insulation from the ends of each wire. Twist the bare wire strands tightly to prevent short circuits.
  2. Identify the positive (+) and negative (-) terminals on both the D-509C speaker and your AV receiver. The positive terminal is usually red, and the negative terminal is black.
  3. Connect the positive (+) terminal of the D-509C speaker to the positive (+) center channel output terminal on your AV receiver.
  4. Connect the negative (-) terminal of the D-509C speaker to the negative (-) center channel output terminal on your AV receiver.
  5. Ensure all connections are secure and that no bare wire strands are touching each other or any other metal parts, which could cause a short circuit.

3. System Configuration

After connecting the speaker, refer to your AV receiver's manual for instructions on configuring speaker settings. This typically involves setting the center speaker to "Small" or "Large" depending on your system's subwoofer presence and crossover frequency. Run any automatic calibration features your receiver may have (e.g., Audyssey, MCACC) for optimal sound balance.

Operating Your Speaker

The Onkyo D-509C is a passive speaker and does not have its own controls. Its operation is managed entirely through your connected AV receiver or amplifier. Ensure your receiver is set to the correct input source and that the center channel volume is appropriately balanced with other speakers in your system.

  • Volume Control: Adjust the overall system volume using your AV receiver's remote control.
  • Channel Levels: If dialogue sounds too quiet or too loud, adjust the center channel level in your AV receiver's speaker setup menu.
  • Listening Position: For the best sound, ensure your primary listening position is centered relative to the speaker and TV.

Maintenance

To maintain the appearance and performance of your Onkyo D-509C speaker, follow these simple guidelines:

  • Cleaning: Gently wipe the speaker cabinet with a soft, dry cloth. For stubborn marks, slightly dampen the cloth with water, then wipe dry immediately. Avoid using abrasive cleaners, solvents, or chemical sprays, as these can damage the finish.
  • Grille: The speaker grille can be carefully removed for cleaning if necessary. Use a soft brush or a vacuum cleaner with a brush attachment to remove dust.
  • Placement: Avoid placing the speaker in direct sunlight, near heat sources, or in areas with high humidity, as these conditions can affect its performance and lifespan.
  • Handling: Do not press on the speaker cones or tweeters, as this can cause damage.
