Compatibility and driving power: designed for large 1018 inch speakers with 4 ohm to 8 ohm impedance, enabling use with common volume drivers. Power and performance: configured for a DC dual power supply of ±65V with better filtering to support stable, clean operation and adequate headroom. Safety features: audio output includes shortcircuit protection to reduce risk; nevertheless, avoid short circuits to protect the amplifier and speaker. Voltage tolerance and operation range: rated for dual supply ±65V and can operate normally within approximately ±58V to ±70V. Do not exceed ±70V, or component damage may occur. Unregulated supply note: if powered from a nonregulated mains source, voltage may vary; allow margin for fluctuations to prevent undervoltage or overvoltage conditions. Polarity and wiring caution: incorrect connection of the power supply positive and negative poles can burn the board; ensure correct polarity and wiring. Practical applications: Home theater or volume stereo setups using large 10–18 inch speakers to achieve robust bass and clear mid/highs with wide compatibility. Small to midsize live sound or PA applications requiring reliable dualsupply power and protection for large drivers. DIY audio projects such as subwoofer or speaker amplifier builds where a stable ±65V supply and protection features improve performance and safety. Summary of key attributes: function as a powerready amplifier with compatible speaker loads, a dual ±65V supply with filtering, protection against shorts, clear operating voltage range guidance, and essential wiring precautions to prevent damage.
