Setup Instructions
Follow these steps to set up your Harman Kardon Rev A00 Computer Speakers:

- Connect Speakers: The speakers are typically connected to each other via an integrated cable. Ensure this connection is secure.

- Connect Power: Plug the power supply cable into the designated power input port on one of the speakers. Then, plug the power supply into a standard electrical outlet.

- Volume Control: Adjust the volume using the knob located on the front of the left speaker. You can also control the volume from your connected device (computer, laptop).
- Audio Playback: Ensure your audio source (computer, laptop) is playing sound. The speakers will output the audio from the connected 3.5mm audio jack.
