2. Connect to Audio Source: Use the included 3.5mm audio cable to connect the 3.5mm input jack on the amplifier to the headphone output or line-out jack of your audio source (e.g., smartphone, MP3 player, laptop).
3. Connect Headphones: Plug your headphones into the 3.5mm output jack on the amplifier.
4. Power On: Rotate the volume knob clockwise until you hear a click and the Power indicator light (PWR) illuminates.
5. Select Gain: Choose the appropriate gain setting (L for Low, H for High) using the gain switch. Start with 'L' for most headphones and switch to 'H' if more volume or power is needed for high-impedance headphones.

Operating Instructions

1. Adjust Volume: Slowly rotate the volume knob clockwise to increase the volume to your desired listening level. Rotate counter-clockwise to decrease.
2. Gain Selection:
   • Low Gain (L): Recommended for sensitive headphones or when the audio source already provides a strong signal. This setting helps prevent distortion and preserves battery life.
   • High Gain (H): Use for high-impedance headphones (e.g., 100Ω-300Ω) or when the audio source's output is low, requiring more power to drive your headphones effectively.
3. Power Off: When finished, rotate the volume knob counter-clockwise until you hear a click and the Power indicator light turns off. This conserves battery life.
