How to use

Place the amplifier on a stable, ventilated surface with adequate clearance around the enclosure. Connect left and right passive speakers to the corresponding speaker outputs using suitable speaker cable, observing polarity. Link your audio source—such as a TV, CD player, computer or streaming device—to the amplifier's input using the appropriate analog connection. Power the unit from a compatible mains supply, switch it on, select the desired input and adjust volume to level. Avoid driving the amplifier to maximum volume for prolonged periods to prevent speaker damage and distortion.

Recommendations

For best results, match the amplifier to speakers with appropriate sensitivity and impedance for low-power amplification, position speakers to optimize stereo imaging, and use quality shielded cables for source connections to reduce noise. Regularly allow ventilation space and avoid enclosing the unit in tightly sealed cabinetry during operation.
