Setup Instructions
- Positioning the Speakers: Place the subwoofer on the floor, ideally near a wall or in a corner for optimal bass response. Position the two satellite speakers on either side of your listening area, such as on a desk or shelf. The satellite speakers feature pivoting stands, allowing you to adjust their angle to direct sound towards your ears.
- Connecting Satellite Speakers to Subwoofer: Connect the cables from the satellite speakers to the corresponding output jacks on the back of the subwoofer. Ensure a secure connection.
- Connecting to an Audio Source:
- For computers, MP3 players, or devices with a 3.5mm headphone jack: Use the provided 3.5mm audio cable to connect the audio output of your device to the 3.5mm input jack on the subwoofer.
- For televisions or video gaming systems with RCA outputs: Use RCA cables (not necessarily included, but the system supports them) to connect the audio output of your TV or gaming system to the RCA input jacks on the subwoofer. The cables are color-coded for easy installation (typically red for right, white for left).
- Connecting to Power: Plug the power cable into the subwoofer's power input, then plug the other end into a standard electrical outlet.
- Initial Power On: Turn on the speaker system using the power button, which may be located on the subwoofer or controlled via the wireless remote.
