Introduction

This manual provides essential information for the proper setup, operation, and maintenance of your Polk Audio RM 6900 Speaker System. Please read this manual thoroughly before using your system to ensure optimal performance and longevity.

The image displays the complete Polk Audio RM 6900 speaker system, featuring two tall, slender front speakers, two smaller satellite speakers, a horizontal center channel speaker, and a compact subwoofer. All components are finished in a sleek, uniform color.

Setup and Installation

Proper setup is crucial for achieving the best sound quality from your RM 6900 system. Follow these steps carefully.

1. Unpacking

• Carefully remove all components from the packaging.
• Verify that all listed components are present: two front speakers, two surround speakers, one center channel speaker, and one subwoofer.
• Retain packaging for future transport or storage.

2. Speaker Placement

Optimal speaker placement enhances the listening experience.

• Front Speakers: Place the front left and right speakers equidistant from your primary listening position, forming an equilateral triangle with the listener.
• Center Channel Speaker: Position the center channel speaker directly above or below your television, centered horizontally.
• Surround Speakers: Place the surround speakers to the sides or slightly behind the listening position, at ear level or slightly above.
• Subwoofer: The subwoofer can be placed in a corner or along a wall for best bass response. Experiment with placement to find the ideal spot for your room.

3. Wiring Connections

Ensure all connections are secure and correct polarity is maintained.

1. Connect the speaker wires from your amplifier/receiver to the corresponding terminals on each speaker. Match positive (+) to positive and negative (-) to negative.
2. For the subwoofer, connect the LFE (Low Frequency Effects) output from your receiver to the LFE input on the subwoofer using an RCA cable. If your receiver does not have an LFE output, use the stereo RCA outputs.
3. Plug the subwoofer's power cord into a wall outlet.

Operating Instructions

Once your system is set up, follow these guidelines for operation.

1. Initial Power On

• Ensure all connections are secure before powering on your receiver and subwoofer.
• Turn on your audio/video receiver first, then the subwoofer.

2. Receiver Configuration

Access your receiver's speaker setup menu to configure the system.

• Set all satellite speakers (front, center, surround) to "Small" or "Crossover" mode.
• Set the subwoofer to "On" or "Yes".
• Adjust the crossover frequency for the satellite speakers, typically between 80Hz and 120Hz, depending on your receiver's capabilities and room acoustics.
• Use your receiver's auto-calibration feature (if available) for precise level and delay settings.

3. Subwoofer Controls

The subwoofer has its own controls for fine-tuning.

• Volume/Level: Adjust to blend seamlessly with the satellite speakers. Avoid setting it too high, which can result in boomy bass.
• Crossover: If your receiver manages the crossover, set the subwoofer's crossover knob to its highest setting (LFE mode). If your receiver does not have LFE management, adjust this knob to match the crossover frequency set on your receiver.
• Phase: Experiment with the 0°/180° phase switch to achieve the most impactful and coherent bass response.

Maintenance and Care

Regular care will help maintain the appearance and performance of your speaker system.

• Cleaning: Use a soft, dry cloth to wipe down the speaker cabinets. Avoid abrasive cleaners or solvents.
• Grilles: The speaker grilles can be gently removed for cleaning if necessary. Use a soft brush or vacuum with a brush attachment to remove dust.
• Placement: Avoid placing speakers in direct sunlight or near heat sources, which can damage the cabinet finish and speaker components.
• Ventilation: Ensure the subwoofer has adequate ventilation, especially around its amplifier plate, to prevent overheating.
