4. Setup
Speaker Placement:
For optimal sound, place the BX3 monitors on a flat, stable surface, ideally at ear level when seated. Position them to form an equilateral triangle with your listening position for the best stereo imaging. Ensure adequate space behind the speakers for proper bass reflex port function.
Connections:
- Connect Active to Passive Speaker: Use the included 1/8” TS Speaker Interconnect Cable to connect the active speaker (the one with controls and power input) to the passive speaker. The active speaker has an “OUTPUT TO PASSIVE SPEAKER” jack.
- Connect to Audio Source: Choose the appropriate cable for your audio source:
- For computers/laptops: Use the 1/8” to 1/8” TRS Aux Cable for the front AUX input, or the 1/8” TRS to RCA Cable for the rear RCA inputs.
- For professional audio equipment: Use 1/4” cables (not included) for the balanced 1/4” inputs on the rear panel.
- Power Connection: Connect the 2-Prong IEC Power Cable to the active speaker’s power input and then to a wall outlet.
5. Operating Instructions
Powering On/Off:
The power switch is integrated with the volume knob on the front of the active speaker. Rotate the knob clockwise until you hear a click to power on the speakers. Rotate counter-clockwise until you hear a click to power off.
Volume Control:
Adjust the overall volume using the PWR/VOL knob on the front of the active speaker. Turn clockwise to increase volume and counter-clockwise to decrease.
EQ Adjustments:
The rear panel of the active speaker features High-EQ and Low-EQ controls. Use these knobs to fine-tune the sound to your preference or room acoustics. Turn clockwise to boost and counter-clockwise to cut the respective frequencies.
Active Speaker Position:
A switch on the rear panel allows you to designate the active speaker as either the right or left channel. This provides flexibility in setup, allowing the volume control to be on the most convenient side.
Front Panel Inputs:
- AUX Input: Connect external audio devices like smartphones or tablets using the 1/8” AUX input.
- Headphone Output: Plug in headphones to the 1/8” headphone jack for private listening. The speaker output will mute automatically when headphones are connected.
6. Maintenance
To ensure the longevity and optimal performance of your M-Audio BX3 monitors, follow these maintenance guidelines:
- Cleaning: Use a soft, dry cloth to clean the exterior of the speakers. Avoid using liquid cleaners or solvents, as they may damage the finish.
- Handling: Handle the speakers with care. Avoid touching the speaker cones (woofers and tweeters) directly, as this can cause damage.
- Ventilation: Ensure that the rear ports are not obstructed to allow for proper airflow and bass response.
- Storage: When not in use for extended periods, store the speakers in a cool, dry place, protected from dust and extreme temperatures.
