How to use

Connect the speakers to the amplifier’s speaker outputs and attach a source via Bluetooth pairing or analog input. Place the amplifier on a stable surface with adequate ventilation and use the front-panel or remote controls to set volume and input selection. For best results, match the amplifier to speakers with compatible power handling and impedance ratings and avoid placing the unit in fully enclosed spaces that impede heat dissipation.
