Setup
Proper placement and connection are crucial for optimal sound performance. The RM6751 speaker is designed for flexible placement within your home theater environment.
1. Speaker Placement
- For 6.1 or 7.1 channel systems, position the RM6751 as a rear or side surround speaker.
- Ensure the speaker is placed at approximately ear level when seated, or slightly above.
- Avoid placing the speaker in enclosed spaces that may muffle the sound.
- The speaker is magnetically shielded, allowing placement near televisions without video interference.
2. Mounting Options
The RM6751 features integrated keyhole slot wall mounting brackets for easy installation.
- Identify a suitable wall location for mounting.
- Securely fasten a screw (not included) into the wall, ensuring it can support the speaker's weight (approximately 2.7 pounds). Leave a small portion of the screw head protruding.
- Align the keyhole slot on the back of the speaker with the screw head and slide the speaker down to secure it.
- Alternatively, the speaker can be placed on a shelf or stand.

3. Connecting to Your Receiver/Amplifier
Use high-quality speaker wire (not included) to connect the RM6751 to the appropriate surround channel output on your home theater receiver or amplifier.
- Ensure your receiver/amplifier is turned off before making any connections.
- Connect the positive (+) terminal (red) on the speaker to the positive (+) terminal on your receiver's corresponding channel.
- Connect the negative (-) terminal (black) on the speaker to the negative (-) terminal on your receiver's corresponding channel.
- Maintain correct polarity for all speakers in your system to ensure proper sound staging.
Operating Instructions
Once the speaker is properly connected, you can begin using your home theater system.
- Power On: Turn on your receiver/amplifier and select the desired audio source.
- Volume Control: Adjust the overall system volume using your receiver's controls.
- Speaker Level Calibration: For optimal surround sound, it is recommended to calibrate your speaker levels using your receiver's built-in auto-calibration feature (if available) or manually adjust them to ensure balanced sound from all channels.
