5. Setup

Follow these steps to set up your XY-S100L amplifier board:

1. Connect Speakers: Connect your passive left, right, and subwoofer speakers to the corresponding screw terminals on the amplifier board. Ensure correct polarity (+ to + and - to -).
2. Connect Audio Source: Connect your audio source device (e.g., phone, computer) to the audio input jack on the amplifier board using an appropriate audio cable.
3. Connect Power: Connect a compatible DC power adapter (not included) to the DC power input jack. Do not connect power until all other connections are secure.
4. Power On: Once all connections are secure, connect the power adapter to a wall outlet. The amplifier board should power on.

6. Operating Instructions

After successful setup, you can begin operating your amplifier board:

1. Adjust Master Volume: Start with the Master Volume knob turned to its minimum position.
2. Play Audio: Begin playing audio from your connected source device.
3. Increase Volume: Slowly turn the Master Volume knob clockwise to increase the overall sound level to your desired listening volume.
4. Tune Subwoofer: Use the "Subwoofer Volume" and "Subwoofer Frequency" knobs to adjust the bass output and crossover point for your subwoofer.
5. Adjust Main Channel Volume: Use the "Left/Right Channel Volume" knob to balance the stereo output.
6. Fine-tune Treble and Bass: Use the "Treble" and "Bass" knobs to adjust the high and low frequencies of the main stereo channels to your preference.

Experiment with the various tuning knobs to achieve the optimal sound balance for your speakers and listening environment.
