DS-1002

main feature: Using the 20-bit word length of the most advanced digital processing technology, the audio signal can be accurately restored, and the sound resolution has excellent sound reproduction ability, and the details and contours are perfectly reproduced. It is extremely energy efficient and has a performance conversion efficiency of up to 90%. Change the phenomenon of heavy, power-consuming, and bulky. With better transient response characteristics, energy is almost always reserved for audio output, making sound detail reproduction more abundant. There is no phase shift in the whole frequency band, the sound field is positioned accurately, and the cutoff frequency of the output filter is designed to be high by using digital filter technology, so as to ensure flat amplitude frequency characteristics and good phase frequency characteristics in 20Hz~20KHz. . Functional protection has: overload, overheat, impedance, short circuit, distortion limiting.

Product description
Parameters
The Class-D DS series is a high-quality digital power amplifier that has been improved by Prudential Audio for three generations.
 
It adopts power amplifier power integrated circuit technology, which integrates PFC+LLC precision high-speed response switching power supply technology to solve the audio modulation generated by the power amplifier power supply. Integrated fidelity, signal-to-noise ratio enhancement technology, and EMC layout technology of the output platform and cutting-edge technology of Hi-Fi applications make Hi-Fi layered, both in terms of parameter indicators and listening evaluations, extremely high The output damping coefficient, the control force of the speaker can still get high-speed dynamic response when working at high power.
 
The linear optocoupler non-destructive pressure limit (limitation) technology for technical applications, up to 90% of the whole machine power efficiency, low heat, dynamic short circuit protection technology, impedance, overload, over temperature control, to ensure the stability of performance.
