數(shù)字功放 DH系列 兩通道

                                         數(shù)字功放 DH系列 兩通道 第1張 
        JL Audio旗下的DH系列專業(yè)功率放大器是CLassD功放的一個(gè)新理程碑。采用先進(jìn)的CLassD功放模塊和高效的
SMPS電源模塊,這讓DH系列具有極高的效率和可靠性,同時(shí)也具有極高的功率密度,僅在1U高度9"深度的標(biāo)準(zhǔn)機(jī)
箱空間內(nèi)就能提供前所未有的強(qiáng)大功率
。
產(chǎn)品特點(diǎn)
1.結(jié)構(gòu)方面采用標(biāo)準(zhǔn)19寸機(jī)架寬度,1U 9寸機(jī)箱設(shè)計(jì),體積小,重量輕,方便安裝;
2.功放方面采用穩(wěn)定高效的ClassD功放模塊,ClassD功放模塊的效率高達(dá)92%以上,這使得DH系列功率放大器具有極高的效率和可靠性。
  同時(shí)也具有極高的功率密度;
3.電源方面采用高效穩(wěn)定的R-SMPS供電系統(tǒng),集成有源功率因數(shù)校正電路(PFC),PFC使DH系列功率放大器具有更高的可靠性和可控制性
  能夠根據(jù)交流電壓波形調(diào)整電流波形、適應(yīng)全球范圍的寬電壓(90V-264V)運(yùn)行,同時(shí)使得單個(gè)標(biāo)準(zhǔn)電流斷路器能夠承載更大的功率。
4.完善的保護(hù)系統(tǒng),有效減少因使用不當(dāng)造成的損環(huán),進(jìn)一步提高機(jī)器可靠性;
5.高效穩(wěn)定的ClassD功放模塊,高效穩(wěn)定的R-SMPS供電系統(tǒng),高效的揚(yáng)聲器反電動勢吸收系統(tǒng);
6.獨(dú)特的削峰限幅器和波紋消除網(wǎng)絡(luò);
7.極其輕便的整機(jī)重量和極小的空間占用率;
8.低音渾厚有力,中高頻通透清晰、悅耳;

應(yīng)用
1.高功率密度和高音質(zhì)要求擴(kuò)聲應(yīng)用
2. KTV/大中型酒吧/咖啡廳/休息室安裝。
3.便攜或者租賃行業(yè)PA系統(tǒng)應(yīng)用。
