Setup
Speaker Placement
Proper speaker placement is crucial for optimal sound performance. Consider the following guidelines:
- Front Speakers: Place the front left and right speakers equidistant from your primary listening position and from each other. They should form an equilateral triangle with the listening position.
- Center Channel Speaker: Position the center speaker directly above or below your television, centered horizontally. This speaker handles dialogue.
- Surround Speakers: Place the surround left and right speakers to the sides or slightly behind the listening position, ideally at ear level or slightly above.
- Subwoofer: The subwoofer can be placed almost anywhere in the room, but experimentation is recommended to find the best bass response. Corner placement often enhances bass output.
Connecting the Speakers
Ensure your receiver or amplifier is turned off before making any connections.
- Satellite and Center Channel Speakers: Connect the speaker wires from your receiver's corresponding speaker outputs (Front Left, Front Right, Center, Surround Left, Surround Right) to the binding posts on each satellite and center channel speaker. Ensure positive (+) terminals on the receiver connect to positive (+) terminals on the speakers, and negative (-) to negative (-).
- Subwoofer: Connect the subwoofer to your receiver's LFE (Low-Frequency Effects) or Subwoofer Pre-Out jack using an RCA cable. Plug the subwoofer's power cord into an AC outlet.
Operating Instructions
Initial Power-Up and Configuration
- After all connections are made, turn on your receiver and the subwoofer.
- Access your receiver's speaker setup menu. Configure the speaker sizes (typically "Small" for satellites and center, "Yes" for subwoofer).
- Set crossover frequencies. A common starting point for the RM6750 satellites is 100-120 Hz.
- Adjust individual speaker levels using your receiver's test tones or an auto-calibration feature if available, to ensure balanced sound.
- Adjust the subwoofer volume control on the subwoofer itself to blend seamlessly with the satellite speakers, avoiding overpowering bass.
Listening Tips
- Experiment with subwoofer placement and phase settings for optimal bass integration.
- Avoid placing speakers directly against walls or in corners, as this can sometimes lead to boomy or unnatural sound, except for the subwoofer which can benefit from corner placement.
- Ensure speaker wires are not tangled or pinched to prevent signal loss or damage.
Maintenance
- Cleaning: Dust the speaker cabinets regularly with a soft, dry cloth. Avoid using harsh chemicals or abrasive cleaners.
- Grilles: The speaker grilles can be carefully removed for cleaning if necessary. Use a soft brush or vacuum with a brush attachment to remove dust.
- Environment: Keep speakers away from direct sunlight, excessive heat, and moisture.
