4.3 Connecting to an Audio System
The FLS-540 WH speakers are passive and require an external amplifier or receiver. They feature screwable and pluggable terminal clamps for easy connection.

- Connect to Speakers: Connect the positive (+) terminal of the speaker to the positive (+) output of your amplifier, and the negative (-) terminal of the speaker to the negative (-) output of your amplifier. Ensure correct polarity for both speakers.
- Connect to Amplifier: Connect the other ends of the speaker cables to the corresponding speaker outputs on your amplifier or receiver.
- Power On: Once all connections are secure, you can power on your amplifier and test the sound.
5. Operation

- Audio Source Selection: Select your desired audio source (e.g., TV, laptop, PC) through your amplifier.
