官方的技术说明
USB interfaces are the most commonly utilized devices for digital audio transmission in a computer-based music playback environment. But the convenience and ease of use often times come at a price of lackluster audio quality to the critical ears of high-end consumer audio aficionados and of professional users. It’s no secret that even the best D/A converters are not capable of reproducing and converting audio via USB at the highest possible level, which is why using digital audio inputs such as AES3 or S/P-DIF yields significantly better results and is generally preferred.
We have invested into our own research to uncover the underlying principles and the root of the problem with high-end audio via USB. In a nutshell, electromagnetic interference of any kind, but particularly those caused by audio computers and other IT devices, will induce noise and seriously disturb the audio transmission. In order to eliminate these disturbances and avoid their damaging effect on the conversion process as much as possible we have developed a new signal-isolating, asynchronous USB interface for the MC-3+ Smart Clock USB. It has been designed as a dedicated building block with a power supply that’s independent from the main board of the unit. In addition, the USB interface is galvanically isolated from the other parts of the circuitry and employs its own ultra-low noise audio oscillators that once again are autonomous and isolated from the other processes. In combination with IT-based high-speed isolators we have achieved exceptional reduction of the impact of noise interference within the USB data stream yielding a USB interface that’s virtually immune to any interference problems caused by PCs, laptops or music servers. At the same time, there are no limitations regarding the possible clock rates for playback from your music library with the MC-3+USB supporting all rates possible up to high-speed USB as well as DSD/DoP streams up to DSD/DoP256.
All of these features in combination with the subsequent re-clocking process, proprietary to MUTEC, leads to a significant acoustic improvement of connected digital audio devices that usually manifests itself in increased width of the sound stage, more precise imaging, and with a more musical representation of the recorded space and the instruments within it. Stock consumer audio devices, laptops, and audio computers can now achieve a new level of sonic perfection that was previously reserved for equipment with much higher price tags.

USB接口是计算机音乐播放环境中最常用的数字音频传输设备。但它的便捷性和易用性通常是在高端消费者音频爱好者和专业用户的批评声中出现的。毫无疑问,即使是最好的D / A转换器也不能在尽可能高的水平上复制和转换音频,这就是为什么使用诸如AES3或S / p - dif这样的数字音频输入会得到更好的结果,而且通常是首选的。


我们已经投入到我们自己的研究中,以发现问题的基本原理和问题的根源,通过USB的高端音频。简而言之,任何种类的电磁干扰,特别是由音频计算机和其他IT设备引起的电磁干扰,都会引起噪声并严重干扰音频传输。为了消除这些干扰,尽可能避免它们对转换过程的破坏性影响,我们已经开发了一个新的信号隔离,异步USB接口用于mc -3 +智能时钟USB。它被设计成一个独立于该单元主板的电源。此外,USB接口从电路的其他部分被电隔离出来,并使用它自己的超低噪声声频振荡器,它再一次独立于其他过程。在与基于itbased的高速隔离器的结合中,我们已经成功地减少了USB数据流中噪声干扰对USB接口的影响,这种USB接口几乎不受个人电脑、笔记本电脑或音乐服务器的任何干扰问题的影响。与此同时,在您的音乐库中,使用mc -3+ USB支持所有可能的高速USB以及DSD / DoP流到DSD / DoP256的所有可能的时钟频率,并没有任何限制。


所有这些特性结合后续re-clocking过程,专有MUTEC,导致显著地提高声连接数字音频设备,通常体现在摄影棚的宽度增加,更精确的成像,更记录空间和乐器的音乐表示。股票消费音频设备,笔记本电脑和音频计算机现在可以达到一个新的水平的声音完美,以前为设备而保留的价格更高的标签。

The MC-3+ Smart Clock USB enables bi-directional audio format conversion (half-duplex) between USB audio streams, AES3, AES3id, and S/P-DIF signals. In addition to a variety of digital audio outputs like most other competing devices, it furthermore also provides a full set of digital inputs for AES3, AES3id, and S/P-DIF signals with BNC, RCA, and optical connectivity. Audio streams received via USB will always be converted to five audio outputs allowing multiple devices to receive the same audio simultaneously. Upon selecting one of the audio inputs, the signal will be converted into a USB audio stream to be sent to the computer. At the same time, the source signal will also be converted to the digital outputs of the MC-3+USB, which can be used for monitoring purposes or a digital peak meter, while audio is recorded in the computer via USB. The re-clocking process takes care of delivering your audio at the utmost precision in both cases.
Apart from transmitting standard PCM audio the USB interface is further capable of receiving native DSD and DoP streams with up to four times the SACD clock rate (DSD256). These streams will be re-clocked and converted to PCM audio by the MC-3+USB in realtime to pass them on to the five audio outputs simultaneously. The desired clock rate for the digital outputs can be selected on the front panel with options between 44.1 kHz, 88.2 kHzand 176.4 kHzthat are independent from the clock rate of the incoming DSD or DoP streams.
High-end D/A converters or premium music servers often provide BNC connectors for the transmission of S/P-DIF signals, which are the best choice due to their superior electrical properties compared to the RCA connector. With the MC-3+USB you can conveniently convert USB-PCM, DSD/DoP, or AES3 streams to the S/P-DIF format and send it to appropriately equipped high-end receivers via BNC. Four additional outputs in other formats may be used simultaneously to drive digital headphone amps or other digital audio devices for recording and/or monitoring.
While the MC-3+USB is playing back your precious music via the digital audio outputs, the four Word Clock outputs simultaneously provide phase-coherent clock signals. Since those are derived from the internal re-clocking process they have the same ultra-low jitter qualities as the basic clock signal embedded in the audio signals. Furthermore, the clock outputs may be independently switched in pairs to scale to clock rates of up to FS1 x 512, coming out to 22.5792 MHz or 24.576 MHz respectively making the Word Clock signals of MC-3+USB are ideally suited to clock a wide range of studio equipment and high-end DACs, CD players, and audio interfaces from manufacturers such as Esoteric, TACT Audio or M2Tech (e.g. hiFace Evo).

mc- 3 +智能时钟USB支持USB音频流、AES3、AES3id和S / p - dif信号的双向音频格式转换(半双工)。除了像大多数其他竞争设备一样的数字音频输出,它还为AES3、AES3id和S / p - dif信号提供了一组完整的数字输入,并带有BNC、RCA和光学连接。通过USB接收的音频流将被转换为五个音频输出,允许多个设备同时接收相同的音频。在选择一个音频输入后,信号将转换成一个USB音频流发送到计算机。与此同时,源信号也将转换为mc -3+ USB的数字输出,可用于监控目的或数字峰值表,而音频则通过USB存储在计算机中。在这两种情况下,再锁定过程都需要非常精确地传送音频。


除了传输标准的PCM音频外,USB接口还可以接收本地的DSD和DoP流,其速度是SACD时钟频率的4倍(DSD256)。这些流将被重新锁定并转换为PCM音频,由mc -3+ USB实时将它们传递到五个音频输出同时。数字输出的期望时钟频率可以在面板上选择,选项在44.1 kHz、88.2 kHz和176.4 kHz之间,独立于输入DSD或DoP流的时钟频率。


高端的D / A转换器或高级音乐服务器通常提供BNC连接器来传输S / p - dif信号,这是由于其优越的电气性能与RCA连接器相比的最佳选择。使用mc -3+ USB可以方便地将USB - pcm,DSD / DoP,或AES3流转换成S / p - dif格式,并通过BNC将其发送到适当装备的高端接收器。可以同时使用其他格式的四种输出来驱动数字耳机amps或其他数字音频设备进行记录和/或监视。


当mc -3+ USB通过数字音频输出回放你的珍贵音乐时,四个字时钟输出同时提供相一致的时钟信号。由于这些是源自内部的再锁过程,它们具有与嵌入在音频信号中的基本时钟信号相同的超低抖动特性。此外,独立时钟输出可能会转换成对规模FS1 x 512的时钟频率,分别出来22.5792 MHz或24.576 MHz使这个词的时钟信号MC-3 + USB适合时钟广泛的工作室设备和高端dac,CD播放机,和音频接口等制造商的深奥,机智音频或M2Tech(例如hiFace Evo)。






而其可以配同款的10M外置时钟
REF_10_FB0001.jpg
貌似只有黑色的
REF_10_FB0025.jpg
参数说明:

MUTEC REF 10是一个拥有10兆赫兹信号的发烧友参考主时钟,它具有行业领先的低相位噪声(即抖动),以显著改善数字回放系统。作为你家里数字音频管弦乐队的指挥,REF 10将以前所未闻的清晰、优美的动态和纯音乐来激励你。它是市场上最灵活、最兼容的10 MHz时钟,可以让你少花点时间去担心整合,让你有更多时间享受快乐的回放。


解锁一个更动态、更透明的声音舞台,具有非凡的空间性和细节水平,没有任何数字模糊。对于所有的音乐爱好者来说,要达到信号纯度、音质和时钟精度的顶峰,REF 10是你的数字回放链的必备品。

  • Audiophile 10 MHz reference generator with industry’s lowest phase noise
  • Improves and enhances compatible DACs, audio re-clockers, music servers, and master clocks
  • Engineered around a handcrafted, ultra-low phase noise OCXO made in Germany
  • Generates a very high slew-rate square wave signal for superior lock precision compared to the sine wave signals used by competing brands
  • Provides simultaneous reference outputs with 50 and 75 Ω impedance for maximum compatibility with clocks and DACs by other manufacturers
  • Eight galvanically isolated, individually switchable BNC clock outputs
  • Revolutionary, sub-Hz optimized, lowest noise power supply for every circuit section
  • Integrated, highest-quality international linear power supply
  • Highly efficient power line filtering
  • Intuitive user interface with noble aesthetics
  • Rack-mountable with optional mounting brackets for studio use (2 RU)
  • 3-year extended manufacturer-guaranteed warranty
  • 这个时钟50欧75欧输出都有,应该适应性不错
  • 目前可用的数字转换器、主时钟和音频再clockers在复制或处理数字音频时表现得很好。即便如此,我们在MUTEC认为,现有的解决方案无法实现音频产品的全部潜力。在我们致力于推进艺术和科学的现状的承诺中,我们开始研究进一步提高数字音频系统性能的可能性。为此,我们招募了德国最著名的射频工程师之一加入我们的研发团队。我们一起开发了一个主时钟发生器,它的技术性能超出了我们的想象。技术性能的影响随后被一组经验测试的测试人员验证,以确保高端的性能转换为一流的声音。


    我们的广泛努力的最终结果是REF 10:一个高级的10 MHz参考主时钟和我们的第一个Empyreal类产品,它将不妥协的工程与简单性和最高时钟精度结合在一起。

  • 我们的研究表明,基于铷或铯振荡器的所谓“原子钟”的高时钟稳定性仅限于长期的时域。这种长期稳定指的是绝对时钟频率(在这种情况下每秒10兆赫,或1000万周期)随时间漂移。虽然这种长期的稳定性可能对某些电信应用程序有用,但实际上与数字音频的目的无关。最终,当数字音频流从一个设备传输到另一个设备时,从一个样本到另一个样本的时间,需要尽可能精确地达到最好的声音质量。短期稳定性的波动被测量为抖动或相位噪声,是任何数字音频设备的音频设备的核心。


    与这些“原子钟”不同的是,REF 10是围绕着在德国制造的MUTEC的手工制造的oven-可控振荡器(OCXO)而设计的,它的时钟稳定性最高,与音频的数字音频性能有关。

  • 听起来很吸引人,不是吗?


当然看起来也是有不足的地方:
一是,网络时代了竟然不支持网络接口。新一代的丹特,AES67之类的。
二是,内置的电源,如果是外置线电,可玩性和提升性应该不错。


MC-3+的价格上我认为是平易近人的,基础版799到,USB版1099刀,如果能配上原厂的10M时钟,我认为是很好的组合,如果我需要数字整形设备,从功能上,支持的音频文件格式上,目测产品的品质上,还有价格上无疑我会选它。

这个东西用过,但只做usb界面使用,有点大材小用了,功能倒是很丰富,只做usb界面的情况下素质比不加线电的hydra还差一些,声音取向倒是挺中正的,可能还是用做时钟或者数字整形或者用两个一个带usb的做界面一个不带usb的做加持更合适一点。
