3. Setup

3.1. Speaker Placement

The Borea BRA1-3D speakers offer flexible placement options to optimize your home theater sound:

• Vertical 3D Effects (Atmos/DTS:X/Auro 3D): Place the BRA1-3D speakers directly on top of your main front or surround speakers. Ensure the angled front is facing upwards towards the ceiling. This configuration utilizes sound wave reflection to create an immersive overhead sound experience.
• Horizontal Effect Speakers (Surround): For traditional surround sound, the BRA1-3D speakers can be mounted on the back or side walls. Utilize the integrated mounting system for secure installation. Position them at ear level or slightly above for optimal sound dispersion.

The angled front design is crucial for directing sound waves precisely, whether upwards for 3D effects or directly towards the listening area for surround sound.

3.2. Connections

Connect the BRA1-3D speakers to your amplifier or AV receiver using high-quality speaker cables. Observe correct polarity (positive to positive, negative to negative) to ensure proper phase and sound reproduction.

• The speakers have a nominal impedance of 8 Ohms (minimum 4.5 Ohms), making them compatible with a wide range of amplifiers.
• Ensure your amplifier can safely drive speakers with this impedance rating.

4. Operating Instructions

4.1. Crossover Adjustment

The Borea BRA1-3D speakers feature an adjustable crossover. This allows you to optimize their performance based on their placement and intended use:

• Upward-Firing (Vertical 3D): Select the appropriate crossover setting for upward-firing operation. This setting is designed to complement the reflection of sound off the ceiling for immersive 3D audio.
• Direct-Firing (Horizontal Surround): Select the appropriate crossover setting for direct-firing operation when used as traditional surround speakers. This setting optimizes the sound for direct listening.

Refer to your AV receiver's setup menu for speaker configuration and calibration. It is recommended to run an automatic room correction system (if available) after speaker placement and connection to fine-tune the sound.

4.2. System Configuration

These speakers are designed to integrate into various home theater configurations, from a basic 3.1.2 system to an advanced 9.2.4 setup. The specific configuration will depend on your AV receiver's capabilities and the number of speakers in your system.

• A 3.1.2 system includes three front channels (left, center, right), one subwoofer, and two overhead/height channels (provided by the BRA1-3D speakers).
• A 9.2.4 system would involve nine main channels, two subwoofers, and four overhead/height channels.

Consult your AV receiver's manual for detailed instructions on configuring your specific surround sound setup.

5. Maintenance

To ensure the longevity and optimal performance of your speakers, follow these maintenance guidelines:

• Cleaning: Gently wipe the speaker cabinets with a soft, dry cloth. Avoid using abrasive cleaners, solvents, or excessive moisture, as these can damage the finish.
• Grilles: The speaker grilles can be carefully removed for cleaning. Use a soft brush or vacuum cleaner with a brush attachment to remove dust.
• Placement: Avoid placing speakers in direct sunlight, near heat sources, or in areas with high humidity.
• Handling: When moving speakers, always lift them carefully and avoid dropping them.

6. Troubleshooting

If you encounter issues with your speakers, refer to the following common troubleshooting steps:

• No Sound:
  • Check all cable connections between the speakers and the amplifier/receiver. Ensure they are secure and correctly polarized.
  • Verify the amplifier/receiver is powered on and the correct input source is selected.
  • Confirm the volume is not muted or set too low.
• Distorted Sound:
  • Reduce the volume level on your amplifier/receiver.
  • Check speaker wire connections for any loose strands or short circuits.
  • Ensure the amplifier is not overdriven or clipping.
• Unbalanced Sound:
  • Check the balance settings on your amplifier/receiver.
  • Ensure both speakers are connected with correct polarity.
  • Verify speaker placement is symmetrical relative to the listening position.

If problems persist, consult your amplifier/receiver manual or contact Triangle customer support.
