4. Setup

4.1 Speaker Placement

The BR10 speakers are designed for floor standing placement. For optimal stereo imaging and soundstage, position the speakers equidistant from your primary listening position and away from walls to minimize reflections. Experiment with toe-in (angling the speakers slightly towards the listening position) to find the best sound balance for your room.

4.2 Connecting to Your Amplifier

The BR10 features a dual terminal design, allowing for bi-wiring or bi-amping if your amplifier supports it. For standard connections, ensure the metal jumpers connecting the upper and lower terminals are in place. Use high-quality speaker cables with a cross-section of 4mm² or standard banana plugs for secure connections.

1. Turn off your amplifier: Before making any connections, ensure your amplifier is powered off and unplugged from the mains.
2. Identify terminals: Locate the dual terminal posts on the rear of each BR10 speaker. These are typically color-coded (red for positive +, black for negative -).
3. Connect speaker cables: Connect the positive (+) terminal of the speaker to the positive (+) terminal of the corresponding amplifier channel. Similarly, connect the negative (-) terminal of the speaker to the negative (-) terminal of the amplifier. Ensure correct polarity for both speakers.
4. Secure connections: Tighten the binding posts firmly but do not overtighten. If using banana plugs, insert them fully into the posts.

4.3 Amplifier Recommendations

The BR10 speakers are designed to work with amplifiers providing 75W to 350W of power at 8 ohms. Ensure your amplifier's output impedance matches the speaker's impedance for optimal performance and to prevent damage.

5. Operating Instructions

Once your BR10 speakers are correctly connected to your amplifier, operating them is straightforward:

1. Power on: Turn on your amplifier and any connected audio sources (e.g., television, laptop, gaming console, home theater receiver).
2. Select input: Select the appropriate input on your amplifier for the audio source you wish to play.
3. Adjust volume: Start with a low volume level and gradually increase it to your desired listening level. Avoid excessively high volumes that can cause distortion or damage to the speakers.
4. Audio Output Mode: The BR10 speakers are suitable for surround sound setups, offering a versatile audio experience.

Control of the audio playback (volume, source selection) will typically be managed through your connected amplifier or audio source's remote control.

6. Maintenance

Proper maintenance will help preserve the appearance and performance of your BR10 speakers:

• Cleaning the Cabinet: Use a soft, dry, lint-free cloth to wipe down the speaker cabinets. For stubborn marks, a slightly damp cloth can be used, followed immediately by a dry cloth. Avoid using chemical cleaners, polishes, or abrasive materials, as these can damage the MDF finish.
• Cleaning Drivers: The tweeter (silk dome), midrange (natural cellulose pulp), and woofers (fiberglass membrane) should be cleaned with extreme care. Use a soft brush or compressed air to gently remove dust. Do not touch the driver cones directly.
• Grills: The magnetic grills can be removed for cleaning. Gently wipe them with a soft, dry cloth.
• Environment: Avoid placing speakers in direct sunlight or near strong heat sources, which can cause discoloration or damage to the cabinet materials. Maintain a stable room temperature and humidity.

7. Troubleshooting

If you encounter issues with your BR10 speakers, refer to the following common troubleshooting steps:

• No Sound:
  • Check all cable connections between the speakers and the amplifier. Ensure they are secure and correctly connected (positive to positive, negative to negative).
  • Verify the amplifier is powered on and the correct input source is selected.
  • Check the volume level on your amplifier and audio source.
  • Ensure the metal jumpers on the speaker terminals are in place if not bi-wiring/bi-amping.
• Distorted Sound:
  • Reduce the volume level. Distortion often occurs when the amplifier or speakers are overdriven.
  • Check speaker cable connections for any loose strands or short circuits.
  • Inspect speaker drivers for any visible damage.
  • Ensure your amplifier's power output is within the recommended range for the BR10 speakers.
• Uneven Sound (one speaker louder/quieter):
  • Check individual speaker cable connections for the affected speaker.
  • Verify balance settings on your amplifier or audio source.
  • Ensure both speakers are placed symmetrically in the room.

If these steps do not resolve the issue, please contact triangle customer support or your authorized dealer.
