Setup
- Connect Speakers: Connect your passive speakers to the speaker output terminals on the rear panel. Ensure correct polarity (+ to + and - to -) for both left (L) and right (R) channels. The amplifier supports speakers with an impedance of 4-8 ohms.
- Connect Audio Source:
- For RCA devices (CD player, DVD player, PC): Use RCA cables to connect your audio source to the "AUDIO INPUT" RCA ports (L and R) on the rear panel.
- For 3.5mm devices (MP3/MP4 player, smartphone): Use a 3.5mm to RCA cable to connect your device to the "AUDIO INPUT" RCA ports.
- Connect Power: Plug the included 3A power supply adapter into the "POWER INPUT" port (DC12-13.5V >3A) on the rear panel, then plug the adapter into a wall outlet.
- Power On: Flip the "POWER" switch on the front panel to the "ON" position.

Operating Instructions
- Power On/Off: Use the "POWER" switch on the front panel to turn the amplifier on or off.
- Adjust Volume: Rotate the large "VOLUME" knob clockwise to increase volume and counter-clockwise to decrease it.
- Tone Control:
- In "TONE" mode (switch set to Tone), use the "TREBLE" and "BASS" knobs to adjust the high and low frequencies to your preference.
- In "DIRECT" mode (switch set to Direct), the tone controls are bypassed, providing the original, unenhanced audio signal.
- Audio Playback: Start playing audio from your connected source device.

Maintenance
- Keep the amplifier in a dry, well-ventilated area.
- Avoid exposing the unit to direct sunlight, high temperatures, or humidity.
- Clean the exterior with a soft, dry cloth. Do not use harsh chemicals or abrasive cleaners.
- Ensure proper ventilation around the unit to prevent overheating.
Troubleshooting
- No Sound:
- Check if the amplifier is powered on and the power indicator light is active.
- Verify all audio cables are securely connected to both the amplifier and the audio source.
- Ensure speaker wires are correctly connected to the amplifier terminals and speakers, observing polarity.
- Increase the volume on both the amplifier and the audio source device.
- Distorted Sound:
- Reduce the volume on both the amplifier and the audio source.
- Check the audio source for distortion.
- Ensure speaker impedance matches the amplifier's specifications (4-8 ohms).
- Amplifier Shuts Down:
- This may indicate the over-voltage protection circuit has activated. Ensure the input voltage does not exceed 14.4 Volts DC.
- Check for proper ventilation to prevent overheating.
