3.3 Speaker Placement

Optimal speaker placement is crucial for achieving the best sound performance.

• Position the BP-9040 speakers equidistant from your primary listening position.
• Ensure there is adequate space around the speakers, especially behind them, to allow the bipolar array to function effectively.
• Avoid placing speakers directly against walls or in corners, as this can negatively impact bass response and imaging.
• The integrated subwoofer requires access to an electrical outlet. Position the speakers within reach of a power source.

3.4 Audio Connections

Connect the BP-9040 speakers to your audio receiver or amplifier.

• Standard Connection: Use high-quality speaker wire to connect the lower speaker terminal posts on the BP-9040 to the corresponding left and right speaker outputs on your receiver. Ensure correct polarity (+ to + and - to -).
• Subwoofer LFE Connection (Optional): For advanced bass management, you can connect the LFE input on the BP-9040 to the subwoofer output (LFE) on your receiver using an RCA cable. This allows your receiver to control the integrated subwoofer's crossover and level.
• Power Connection: Plug the provided AC power cord into the power input on the speaker and then into a wall outlet. The integrated subwoofer requires power to operate.

3.5 Optional A90 Height Speaker Module Installation

The BP-9040 is designed to integrate with the optional Definitive Technology A90 height speaker module (sold separately) for Dolby Atmos and DTS:X immersive sound.

1. Remove the top brushed aluminum plate from the BP-9040 tower speaker.
2. Carefully place the A90 module onto the top of the BP-9040, aligning it with the docking port.
3. Connect the A90 module's speaker terminals to the upper speaker terminal posts on the BP-9040.
4. Refer to the A90 module's instruction manual for specific setup and calibration details.

4. Operating Instructions

4.1 Powering On/Off

Once connected to an AC power source, the integrated subwoofer will power on automatically when an audio signal is detected. It will enter standby mode after a period of inactivity.

4.2 Adjusting Subwoofer Level

The BP-9040 features a volume knob on the rear panel for the integrated subwoofer.

• Increase or decrease this knob to blend the subwoofer's output seamlessly with the main speaker drivers.
• Start with the knob at approximately the halfway point and adjust to your preference.
• If using the LFE connection from your receiver, the receiver's subwoofer level control will primarily manage the bass output.

Definitive Technology's Intelligent Bass Control helps maintain an overall balance between low and mid frequencies, ensuring clear sound.

4.3 System Calibration

For optimal performance, it is recommended to calibrate your entire home theater system using your receiver's automatic calibration feature (e.g., Audyssey, MCACC, YPAO). This process measures speaker distances, levels, and equalization to optimize sound for your listening environment.

5. Maintenance

Proper care will ensure the longevity and performance of your BP-9040 speakers.

• Cleaning: Use a soft, dry cloth to wipe the speaker cabinet. For the grille cloth, a soft brush or vacuum cleaner with a brush attachment can be used to remove dust. Avoid using harsh chemicals or abrasive cleaners.
• Placement: Keep speakers away from direct sunlight, heat sources, and excessive moisture.
• Ventilation: Ensure adequate airflow around the rear panel where the amplifier is located to prevent overheating.
• Power Cord: Regularly inspect the AC power cord for any signs of damage. If damaged, replace it with an approved cord.
