Observe correct polarity: connect the positive (+) terminal of the amplifier to the positive (+) terminal of the speaker, and the negative (-) terminal of the amplifier to the negative (-) terminal of the speaker.
- Connect Audio Source: Use an RCA cable to connect your audio source (e.g., smartphone, tablet, computer, CD player) to the "AUDIO INPUT" RCA ports on the rear panel.
- Connect Power: Plug the included 12V 3A power adapter into the "DC 12V" power input jack on the rear panel. Then, plug the power adapter into a suitable wall outlet.
- Power On: Turn the Power switch on the front panel to the "ON" position. The blue LED on the volume knob will illuminate.
5. Operating Instructions
- Volume Adjustment: Rotate the large central "VOLUME" knob clockwise to increase the volume and counter-clockwise to decrease it.
- Bass Adjustment: Use the "BASS" knob to adjust the low-frequency response of the audio. Turn clockwise for more bass, counter-clockwise for less.
- Treble Adjustment: Use the "TREBLE" knob to adjust the high-frequency response of the audio. Turn clockwise for more treble, counter-clockwise for less.
- FM Radio Function: The amplifier is compatible with a variety of digital products and can automatically search and support FM radio frequencies.
