Introduction
This manual provides detailed instructions for the setup, operation, and maintenance of your Boston Acoustics BA635 3-Piece Multimedia Computer Speaker System. Please read this manual thoroughly before using your speakers to ensure proper installation and optimal audio performance.
Package Contents
Verify that all items listed below are included in your package:
- 1 x Subwoofer (Boston Acoustics BA635)
- 2 x Satellite Speakers
- 1 x Power Adapter
- 1 x Remote Control
- Audio Cables (e.g., 3.5mm stereo audio cable, speaker cables)

Setup Instructions
- Positioning the Speakers: Place the subwoofer on the floor, preferably near your computer. Position the two satellite speakers on either side of your computer monitor, ensuring they are equidistant from your listening position for optimal stereo imaging.
- Connecting Satellite Speakers to Subwoofer: Locate the speaker output jacks on the rear of the subwoofer. Connect the cables from the satellite speakers to these jacks. Ensure a secure connection.
- Connecting Audio Input: Connect the audio input cable (typically a 3.5mm stereo jack) from your computer's audio output port to the "input" jack on the rear of the subwoofer.
- Connecting Power: Plug the power adapter into the "12V in AC/DC" port on the subwoofer. Then, plug the power adapter into a standard electrical outlet.

Operating Instructions
- Power On/Off: The system typically powers on automatically when connected to power and an audio signal is detected. Some models may have a power button on the remote control or a satellite speaker.
- Volume Control: Adjust the main volume using the remote control or the volume knob located on one of the satellite speakers (if present).
- Subwoofer Level: The "subwoofer level" knob on the rear of the subwoofer (refer to Image 2) allows you to adjust the bass output independently. Turn clockwise to increase bass, counter-clockwise to decrease.
- Audio Source: Ensure your computer's audio output is active and the volume is set to an appropriate level.
Maintenance
- Cleaning: Use a soft, dry cloth to clean the speaker surfaces. Do not use liquid cleaners or abrasive materials, as they may damage the finish.
- Placement: Avoid placing speakers in direct sunlight, near heat sources, or in areas with high humidity.
- Cable Management: Ensure all cables are neatly arranged and not pinched or strained to prevent damage.
