    Key Features

    1. Advanced switching mode power supply technology worldwide enables high performance and compact size.

    2. Power factor correction technology (PFC), the realization of very low power consumption and very wide power operating range, power factor up to 0.99, the power range of 90v-270v.

    3. General regulating switch mode power supply with PFC.

    4. Full bridge switching power supply topology, strong current conversion ability, more stable, more reliable.

    5. Power short circuit protection,EMC electromagnetic compatibility

    * Temperature warning: when the temperature reaches 70℃,the LCD screen will give warning, the yellow temperature lamp will be on, the output power will be compressed according to the temperature variable, until the overheating warning is removed, so that the power amplifier will not appear after the overheating protection without sound phenomenon

    * Thermal protection: the maximum normal operating temperature of output level and power supply is 75℃

    * Fixed frequency switch mode output level, to achieve quality of sound accuracy, strong bass, clear and fine treble, music detail performance incisively and vividly

    * HI-FI Class produces unique sound quality
