All amplifiers are designed with solid components.
The amplifier has at least 100～15,000HZ frequency response requirements; the deviation at rated output is +1/-2DB (equalization control reaches "flat").
The frequency response of the power amplifier is lower than 70HZ, attenuation with a slope of 6DB per octave.
The total harmonic distortion of the uncompressed amplifier can not exceed 0.5% at 1000HZ full output; it can not exceed 1% at 50% output.
At rated input, the output level error of the limiter circuit is less than or equal to 3DB, and harmonic distortion of less than or equal to 0.5% is generated when fully restricted.
The output of the amplifier meets the requirements of UIC 568 "Railway Passenger Car Audio Equipment" for frequency characteristics and distortion.
The power amplifier can not be damaged when the input or output is subjected to a short circuit or an open circuit.
The output power of the amplifier can fully meet the input requirements of the speaker.
