product introduction
SONIC PRO®Audio newTDSeries power amplifiers useCLASS-TDClass topology circuit, with high-efficiency power conversion, green and environmentally friendly, is to convert the audio analog signal into a digital signal and then amplify it,TDThe amplifying element of the amplifier is in a switching working state. When there is no signal input, the amplifier is in a cut-off state and does not consume electricity. When working, the input signal is used to make the transistor enter a saturated state. The transistor is equivalent to a switch-on switch, connecting the power supply and the load. Direct switching is converted into an output driving unit, which is very efficient.(can reach80%~98%), we call this type of amplification circuitTDClass amplifier.
product features
Adopt the most advanced digital processing technology20bitThe word length can accurately restore the audio signal, so that both the details and contours of the sound can be perfectly reproduced;
Extremely high efficiency, power conversion efficiency up to90％, has high efficiency and energy conservation unmatched by traditional analog power amplifiers, which has since changed the impression that audio power amplifiers are cumbersome, power-consuming and large in people's minds;
Long life, under the combined effect of high-efficiency, low-power consumption, and digital circuits, the reliability and safety of the power amplifier are greatly improved;
It has good transient response. It does not require the static current consumption of traditional power amplifiers. Almost all of the energy is reserved for audio output. In addition, there is no analog amplification and no negative feedback, so it has better transient response characteristics and allows sound details to be reproduced. Rich;
There is no phase shift in the entire frequency band, and the sound field is accurately positioned. Digital filter and other technologies are used to design the cut-off frequency of the output filter to a high level, thereby ensuring that the output filter is in the range of frequencies.20Hz～ 20KHzSmooth amplitude-frequency characteristics and good phase-frequency characteristics are obtained within;
Strong anti-interference ability,TDThe power amplifier works in a switching state, which has better anti-interference capabilities and makes the sound quality more pure and thorough.TDWe use Huanniu power supply for the power amplifier part of the series, which reflects the greater stability of this series of machines and the pursuit of preferences of industry people.
