WDAC24解码器/耳机放大器的诞生, 重新定义了中价位DAC的新基准。

WDAC24是一款支持192K,24Bit精度的DAC兼耳机放大器,耳机放大器具备耳机阻抗自动识别功能。为了保证WDAC24拥有杰出的性能,香港某著名设计公司(已经签署了NDA,即保密协议,恕不列出公司名称),同英国欧胜( Wolfson)微电子有限公司一起,开发了这款高性能解码器。借助设计公司高超的设计能力,长期同HI-FI以及HI-END名厂合作的经验以及昂贵的实验室支持,确保了WDAC24实现了傲人的客观性能和令人难忘的音质。
   
WDAC24的数字模拟转换部分使用了欧胜公司高性能DAC晶片WM8740,他具有可以接收192KHZ,24Bit的PCM信号,信噪比高达117 dB 。英国欧胜是一家全球领先的IC设计公司,他在高性能DAC芯片领域非常成功。使用欧胜的DAC的知名品牌有莲(Linn),雅俊(Arcam),剑桥(Cambridge),安桥(Onkyo)等等。在48K采样率,24Bit字长,997Hz数字信号输入的时候,WDAC24的THD+N的值为0.0008%!!!  很多DAC芯片拥有类似这样的高性能,但是设计成整机,尤其是商业化整机,由于设计者的专业知识、研发条件以及个人的音乐修养等等问题,设计的整机性能都大打折扣,这是一个非常普遍的现象。一个优秀的音响设备需要优秀的零件,但是只使用优秀的零件绝对不能号称就可以制造出来优秀的音响设备。

对于高端音频设备来说,听者的体验是至关重要的。WDAC24在设计之初,我们就确定了WDAC24的音乐感是首要的前提。聆听WDAC24,美丽的音乐氛围纯净缤纷,以音乐光泽引导出暖色调的泛音,细腻深情的人声使您很容易就沉浸在音乐的国度。在WDAC24的世界里,从欢快活泼的合唱到凝重浑厚的弦乐,你会思考庞大的音乐能量。

毫无疑问,WDAC24配置了高性能的耳机输出,满足众多耳机发烧友的需求。最另人惊奇的是,依靠设计公司强大的硬件和软件开发以及集成能力,WDAC24拥有首创的耳机阻抗自动识别功能。当用户插入耳机后,WDAC24会切断线路输出,内部的处理器会在1秒种之内自动分析耳机的阻抗状况,根据耳机的测试结果自动调整耳机放大器的输出幅度,调节相关驱动参数,自动调整WM8740的数字滤波器状态,并且在面板上点亮相应的指示灯,指示出是高阻抗,还是中阻抗,还是低阻抗。只有这样,才能实现和负载的最佳匹配,才能使音频性能达到一个新的高度。我们考虑到音响系统是一个整体,而不是孤立的一部分,相信有经验的音乐爱好者和音响发烧友都会这样认为。

在产品定义的初期,设计公司就同英国欧胜工程师紧密联系。欧胜的工程师自己设计了WM8740这颗集成电路,最了解他的特点和应用,所以,我们信任他们,是他们给我们提供了原始的设计方案。在产品测试设计的过程中,设计公司反复和欧胜的工程师确认,来保证最终的设计意图。里面密密麻麻的贴片零件,都经过反复的筛选和仔细的确认。在产品设计的最后,我们在欧胜的实验室里,使用音频工业界顶级分析仪AP2722对WDAC24做了严格的测试,并和欧胜的工程师一起反复聆听,评价,才最终定型。

WDAC24具有同轴(COX),光纤(OPT)和USB输入三种方式,每次开机都会记忆上次关机前的输入信道,可谓人性化的设计。输出接口有平衡(XLR),非平衡(RCA)和耳机输出三种,三种输出方式的幅度都可以通过面板的音量按键或者遥控器去控制,非常方便的连接其他音响设备。
亲爱的发烧友,快来品味让你陶醉的WDAC24之声吧!

The advent of DAC / headphone amplifier WDAC24 has re-defined DAC of average price as a new leader.
WDAC24 is not only a DAC supporting 192K,24Bit Data, but also a headphone amplifier with the function of automatically identifying the resistance of headphones. For its exceptional performance, Wolftech spend a large sum of money inviting a famous design company of Hongkong(we have signed the NDA--the confidential agreement with them. Excuse not giving its name ) together with Wolfson Microelectronics Co., Ltd. of England to research and develop this project. With their remarkable design ability and the experience of long-term cooperation with Hi-Fi and Hi-END famous factories, as well as the support of their expensive lab, we guarantee WDAC24 outstanding performance and impressive sound.
The WDAC24 uses high performance WM8740 DAC chip of Wolfson, which can receive PCM signal of 192KHZ, 24BIT, and SNR is up to 117dB. Wolfson is the worldwide leader of IC design and succeeds in highly performanced DAC field. Many famous companies use the DAC of Wolfson, such as Linn, Arcam, Cambridge, Onkyo etc. When input 997Hz digital signal with 96K Sample rate 24Bit,THD+N of WDAC24 is 0.0008%!!! It is very common that other DAC chip also has such performance, but there is deficiency in the performance of a complete set, which is caused by the lack of engineer's specialized knowledge, R&D condition and his right quality for music. A set of excellent audio system requires excellent components, but only excellent components couldn't make excellent audio system.
   For the high-end audio system, what the listener's feel is very important. At the beginning of designing WDAC24, we determined the musical sense to be the first. The ravishing music and deep sense of sound given by WDAC24 will bring you to a wonderful music world where you will wonder at the musical energy from merry chorus to powerful string music.
There is no doubt that WDAC24 meets many headphone lovers' needs for the highly performanced headphone output. It is amazing that WDAC24 can automatically identify the resistance of headphones under the backing of the powerful R&D team with strong ability of hardware and software development. When users plug the headphone in, WDAC24 will cut down the lineout, the processor inside will automatically analyze the resistance within 1 second, and adjust the headphone amplifier output voltage, the related drive spec and the WM8740 digital filter status automatically, lighten the corresponding indicator on the panel in the meantime to tell whether it is high, average or low resistance. In this way, it can match with the load best and make the audio performance reach an another level. We regard audio system as a whole not the separate part, the experienced music lovers may also think so.
The design company has been in contact with Wolfson from the very beginning of product definition. It is the engineers of Wolfson who designed WM8740 and provided the original solution, we trust them since they understand the features and application of this IC. Throughout the course of product test and design, the design company confirmed that with engineers of Wolfson over and again to ensure the final design. The countless SMD components inside have been repeatedly selected and carefully confirmed. Toward the end of design, WDAC24 was strictly tested in the lab of Wolfson by the AP2722 which is the most professional device in audio industry. Then we and engineers of Wolfson listened and evaluated and completed the design finally.
WDAC24 has the input of COX, OPT and USB. It is so smart that when powered on, it can memorize the last input souse before powered off. It has the output of XLR, RCA and headphone out. The amplitude of these three kinds of output can be controlled by the volume button on the panel or with remote control. It is very convenient to connect to other audio device.
Come on, lovers of music! Enjoy WDAC24 sound!
