Installation
1. Déballage
Carefully remove all components from the packaging. Retain the original packaging for future transport or storage. Inspect all items for any signs of damage. If any damage is found, contact your dealer immediately.
2. Emplacement des haut-parleurs
Optimal placement of your Mass 5.1 speakers is crucial for achieving the best surround sound experience. Consider the following guidelines for a typical 5.1 setup:
- Haut-parleurs avant gauche et droit : Place these speakers equidistant from your primary listening position, forming an equilateral triangle with the listener. They should be positioned at ear level when seated.
- Haut-parleur central : Position the center speaker directly above or below your television/screen, centered with the viewing area. It should be aligned with the front left and right speakers.
- Enceintes surround gauche et droite : Place these speakers to the sides or slightly behind the main listening position, approximately 90-110 degrees off-axis from the center. They should be slightly above ear level.
- Subwoofer: Subwoofer placement is less critical than satellite speakers, but generally, corner placement can enhance bass output. Experiment with different positions in your room to find the best balance of bass response and integration with the satellite speakers.
3. Connexions
Before making any connections, ensure your AV receiver and the Mass Subwoofer are powered off and unplugged from the mains electricity supply.
- Connexion des enceintes satellites :
Use high-quality speaker cables to connect each Mass Satellite Speaker to the corresponding speaker terminals on your AV receiver. Ensure correct polarity: connect the positive (+) terminal on the speaker to the positive (+) terminal on the receiver, and the negative (-) terminal on the speaker to the negative (-) terminal on the receiver. Incorrect polarity can result in poor sound quality.
The satellite speakers have a maximum output power of 25 Watts. Ensure your receiver's output matches the speaker's requirements.
- Connexion du caisson de basses :
Connect the Mass Subwoofer to your AV receiver using a dedicated subwoofer (RCA) cable. Connect the LFE (Low-Frequency Effects) output on your receiver to the LFE input on the subwoofer. If your receiver does not have an LFE output, use a standard RCA cable to connect the receiver's subwoofer pre-out to the subwoofer's line-level input.
The subwoofer operates on 230 Volts AC power. Connect the supplied power cable to the subwoofer's power input and then to a suitable wall outlet.
Once all connections are made, you can plug in your AV receiver and the subwoofer, and power them on. Refer to your AV receiver's manual for initial setup and calibration, including speaker level and distance settings.
Opérationnel
The MONITOR AUDIO Mass 5.1 system is designed to work in conjunction with an AV receiver, which will control the overall system volume and sound modes.
Commandes du caisson de basses
The Mass Subwoofer features several controls on its rear panel to optimize its performance within your system:
- Volume: Adjusts the output level of the subwoofer. Start with a moderate setting and fine-tune during system calibration.
- Croisement : Determines the highest frequency the subwoofer will reproduce. This should be set to blend seamlessly with your satellite speakers. A common starting point is 80Hz, but adjust based on your room and speaker characteristics.
- Phase: Allows you to adjust the phase of the subwoofer's output (0° or 180°) to ensure it is in phase with your main speakers, preventing cancellation or reinforcement of bass frequencies. Experiment with both settings to find the one that produces the most impactful and coherent bass.
- Mode d'alimentation : Typically includes 'On', 'Auto', and 'Off'. 'Auto' mode will power on the subwoofer when an audio signal is detected and power off after a period of inactivity.
For detailed calibration, refer to your AV receiver's auto-calibration system (e.g., Audyssey, MCACC, YPAO) if available, or perform a manual setup using a sound level meter.
Entretien
Proper care and maintenance will ensure your MONITOR AUDIO Mass 5.1 system provides years of enjoyment.
- Nettoyage: Use a soft, dry, lint-free cloth to gently wipe the surfaces of the speakers and subwoofer. Do not use abrasive cleaners, solvents, or chemical sprays, as these can damage the finish.
- Grilles: The speaker grilles can be carefully removed for cleaning if necessary. Use a soft brush or a vacuum cleaner with a brush attachment on a low setting to remove dust.
- Environnement de stage : Avoid placing speakers in direct sunlight, near heat sources, or in areas with high humidity. Ensure adequate ventilation around the subwoofer, especially its rear panel, to prevent overheating.
- Manutention: Always handle the speakers and subwoofer with care. Avoid touching the speaker drivers directly.
Dépannage
If you encounter issues with your Mass 5.1 system, refer to the following common problems and solutions:
| Problème | Cause possible | Solution |
