Setup

Placement Considerations

Proper placement of your center channel speaker is critical for optimal sound performance, especially for dialogue clarity in a home theater setup.

• Ear Level: Position the speaker as close to ear level as possible when seated. This typically means placing it directly above or below your television or projection screen.
• Centered: Ensure the speaker is horizontally centered with your display to maintain a cohesive soundstage.
• Clear Path: Avoid placing objects in front of the speaker that could obstruct the sound.
• Surface Stability: Place the speaker on a stable, flat surface. The built-in pad on the bottom helps isolate it from the surface.

Connecting the Speaker

The Monolith THX-365C uses high-quality binding posts for secure connection to your amplifier or AV receiver.

1. Turn off your amplifier or AV receiver before making any connections.
2. Prepare your speaker wire by stripping approximately 0.5 inches (1.2 cm) of insulation from both ends. Twist the bare wire strands tightly.
3. Unscrew the binding post caps on the back of the speaker.
4. Insert the positive (+) wire (usually red or marked) into the red binding post and the negative (-) wire (usually black or unmarked) into the black binding post.
5. Tighten the binding post caps securely to ensure a firm connection.
6. Connect the other end of the speaker wire to the corresponding positive (+) and negative (-) speaker terminals on your amplifier or AV receiver. Ensure polarity is consistent (+ to + and - to -) for all speakers in your system.

Operating Instructions

Initial Power-On and Calibration

After connecting your speaker, follow these steps:

1. Turn on your AV receiver or amplifier.
2. Access your receiver's speaker setup menu.
3. Set the center channel speaker to "Small" and the crossover frequency to 80 Hz. This directs low-frequency sounds to your subwoofer, allowing the center speaker to focus on dialogue and mid-range frequencies.
4. Run your receiver's automatic room correction system (e.g., Audyssey, MCACC, YPAO, Dirac Live) if available. This will calibrate speaker levels, distances, and equalization for your listening environment.
5. If no auto-calibration is available, manually adjust the center channel level to match other speakers in your system using a sound level meter or by ear.

Listening Recommendations

The Monolith THX-365C is designed for accurate sound reproduction. For the best experience:

• Ensure your audio source is of high quality.
• Avoid excessively high volume levels that cause audible distortion.
• Experiment with minor adjustments to speaker placement to fine-tune the soundstage in your room.

Maintenance

To ensure the longevity and performance of your Monolith THX-365C speaker, follow these simple maintenance guidelines:

• Cleaning: Use a soft, dry cloth to wipe down the cabinet. For the grille, a soft brush or vacuum cleaner with a brush attachment can be used to remove dust. Avoid using liquid cleaners or abrasive materials.
• Environment: Keep the speaker away from direct sunlight, heat sources, and excessive moisture.
• Connections: Periodically check speaker wire connections to ensure they remain secure. Loose connections can degrade sound quality.
