4. Setup
4.1 Placement
The R400 is designed to be the voice of your home theater system. Optimal placement is crucial for clear dialogue and balanced sound. Place the center channel speaker directly below or above your television, centered horizontally with the screen. Ensure it is positioned at or near ear level when seated in your primary listening position.
- On a Stand/Shelf: Ensure the surface is stable and can support the speaker's weight (approximately 32.8 lbs).
- Wall Mounting: The R400 can be wall-mounted using appropriate hardware (not included) and the integrated rubber feet for stability. Consult a professional for wall mounting to ensure safety and proper installation.

4.2 Connections
Connect the R400 to the center channel output of your AV receiver using high-quality speaker wire. The speaker features premium, large 5-way binding posts for a secure and lossless connection.
- Ensure your AV receiver is turned off before making any connections.
- Strip approximately 1/2 inch (12mm) of insulation from the ends of your speaker wire.
- Twist the bare wire strands tightly.
- Unscrew the binding post caps on the R400 and your AV receiver.
- Insert the bare wire into the hole in the binding post. Connect the positive (+) terminal (red) on the speaker to the positive (+) terminal on your receiver, and the negative (-) terminal (black) on the speaker to the negative (-) terminal on your receiver.
- Tighten the binding post caps securely, ensuring no stray wire strands are touching other terminals.

5. Operating Instructions
Once connected, your R400 Center Channel Loudspeaker is ready for use. The speaker is designed to integrate seamlessly into a multichannel surround sound system.
- AV Receiver Calibration: It is highly recommended to run your AV receiver's automatic room calibration (e.g., Audyssey, MCACC, YPAO) after connecting the R400. This will optimize the speaker's performance for your specific room acoustics.
- Volume Control: Adjust the volume through your AV receiver. The R400 is capable of handling up to 200 Watts of power.
- Break-in Period: Like all high-fidelity speakers, the R400 may benefit from a break-in period of several hours of normal listening to achieve its optimal sound performance.

6. Maintenance
To ensure the longevity and optimal performance of your R400 loudspeaker, follow these simple maintenance guidelines:
- Cleaning: Dust the cabinet and grille gently with a soft, dry cloth. Avoid using harsh chemicals, abrasive cleaners, or excessive moisture, as these can damage the finish or components.
- Grille Care: The magnetic grille can be removed for cleaning or for a different aesthetic. Handle it carefully to avoid bending or damaging the fabric.
- Placement Environment: Avoid placing the speaker in direct sunlight, near heat sources, or in areas with high humidity. Ensure adequate ventilation around the speaker.
- Driver Protection: While the drivers are robust, avoid touching them directly to prevent accidental damage.
7. Troubleshooting
If you experience issues with your R400 loudspeaker, consult the following common troubleshooting steps:
- No Sound:
- Check all speaker wire connections at both the speaker and the AV receiver. Ensure they are secure and correctly matched (positive to positive, negative to negative).
- Verify that the AV receiver is powered on and set to the correct input source.
- Confirm that the center channel output is enabled and not muted in your AV receiver's settings.
- Distorted Sound:
- Reduce the volume on your AV receiver.
- Check speaker wire connections for loose strands or short circuits.
- Ensure the speaker is not overdriven. If distortion occurs at moderate volumes, your amplifier may be underpowered or clipping.
- Weak Bass:
- Verify that the speaker is correctly configured as a "Small" or "Large" speaker in your AV receiver's settings, and that the crossover frequency is appropriately set (typically 80Hz for most systems).
- Ensure the X-Port is not obstructed.
- Consider running your AV receiver's room correction software again.
- Unbalanced Sound/Dialogue Unclear:
- Confirm the speaker is centered relative to your listening position and television.
- Check the channel levels in your AV receiver's settings to ensure the center channel is not set too low.
- Ensure the speaker is not obstructed by furniture or other objects.
If these steps do not resolve the issue, please contact Polk Audio customer support for further assistance.
