MC3+

Lowest-Jitter Master Clock and Audio-Re-Clocker

"When plugging in the MUTEC MC3+ for the first time, the results were immediate. I didn't have to convince myself that what was coming out of the speakers was tighter, more detailed, and expansive." – Alex DeTurk, Tape Op – March 2015

The MC3+ is developed to significantly improve the audiophile quality of connected digital audio devices in two ways: At first by clocking devices with ultra-low-jitter Word Clock signals and secondly by aggressively re-clocking incoming digital audio signals.

  • Incorporates MUTEC's unique 1G-Clock Technology for lowest jitter possible
  • Improves audiophile quality of any connected digital audio device
  • Re-clocks digital audio most aggressively
  • Raises clearly audible the sound quality of any DA converter
  • Eliminates digital "Clicks and Pops"
  • Enhances existing master clocks
  • Digitally-compensated clock accuracy for highest precision of the generated clocks
  • Locks to 10 MHz clock signals of so-called Atomic clocks or GPS receivers
  • Outputs clock signals fail-safe in any state of operation
  • Generates Word Clocks, Super Clocks, AES3 + S/P-DIF blanks simultaneously
  • Converts between AES3 and S/P-DIF as well as between AES11 and Word Clock
  • Generates Word Clocks up to 768.0 kHz
  • New-designed, simple user interface
  • Front panel lock-out for preventing misuse
  • Rack-space-saving 9.5" housing
  • Built-in, international power supply

Enhancement of Sound Quality by high-resolution Audio Re-Clocking

It is widely known that a master clock changes the sound quality of digital audio devices more or less to a higher level. But carving out finest audio details in your recordings to reproduce individual instruments as clear as possible and to raise the precision of their positions within the spatial sound to a maximum is possible at best with high-resolution re-clocking of your digital audio material. That is what MUTEC's new audio re-clocking algorithms paired with the 1G-Clock technology perform in the MC3+. Thus, the sensing of the incoming audio is carried out with highest resolution which leads to ultimate precision during merging the audio data with the new ultra-low-jitter clock. The result is unparalleled richness of details and spatiality of the re-clocked audio material.


The real next Step in Audio Clock Generation

While others argue for their products with standardly known technical aspects, MUTEC really sets the benchmark of digital audio clocking to a higher level using the proprietary 1G-Clock technology for the first time in the MC3+. Running a frequency synthesis on a specifically calculated high clock rate, eliminates completely typical jitter inducing artifacts which are present in all standardly implemented DDS processes. Additionally, we took a look around the clock generation circuit and developed totally new ultra-low-noise power supplies and PCB design rules aligned to high-speed communication technologies to virtually eliminate all electrical noise. Thus, the new 1G-Clock technology helps you to bring jitter down to an unique low level, which leads to unprecedented transparency in your audio recordings.


Usability in Studio and Live Event Environments

The new MC3+ works not only as generator, but also as clock distributor. Unlike other products, the MC3+ effectively regenerates incoming clock signals to higher purity as the signal source. This helps to stabilize already existing clock systems and improves the level of sound reproduction quality in your studio environment. In cases when the MC3+'s digitally-compensated clock accuracy is not sufficient, it is possible to lock the system to references of higher accuracy like so-called Atomic clocks or GPS receivers to raise the timing accuracy to the highest possible level. Additional to that, for the use during live events or in mobile trucks, the MC3+ features anytime-fail-safe clock generation in every state of operation. Entering the hold-over-mode and re-synchronization of returning clock references is carried out so smoothly that live recordings will surely not be affected. Thus, the new MUTEC MC3+ ensures flawless synchronization of connected devices at any time, while enhancing the sound of your audio production impressively.

    "I like the way the MUTEC MC3+ affects my workflow. It sounds smooth and easy on the ear, very clear and detailed, and the stereo image is wide and open. This clock impressed me after less then five minutes of testing, so I bought it on the spot. I actually keep a spare of the MC3+ around as a backup unit just to make sure I never have to work without it."

    "After having been introduced to the concept of reclocking with the MUTEC MC3+ as a sound quality improving technology, and later adopting a double reclocked setup due to its clearly audible effects, I decided to try the cascaded reclocking after reading the test on MUTEC’s website. To cut to the chase: even if the whole endeavor sounds a bit crazy, I can’t help but confirm the exact results documented in the multi-reclocking test. There is absolutely no way I could go back from the four levels of reclocking with the MC3+. I've just made it to the quad reclocking Nirvana. Pure silk!"

    "I demo'ed the MC3+ as I operate quite a complex digital studio with 5 converters (all from different manufacturers) so it seemed prudent to add a master clock to the rig. To me the MC3+ is improving the sound of my studio right throughout the mixing process. This cumulative improvement in audio quality is making my mixes work better. I am currently mixing for artists such as Innervisions / Ame & Tale of Us [R&S records] so my clients are very discerning and I strive for absolute best sonic quality at all times. A lot of my music ends up on vinyl too - my mastering engineer & I maintain 96 kHz audio resolution all the way to final master. I mix in Protools HDX but also use Lynx, Universal Audio & RME converters."

    "I've always been fascinated by the sonic difference clocking can make on a converter and at the same time frustrated by the cost of the best clocks on the market. After an extensive test of the most common and the most expensive clocks on the market I stumbled upon MUTEC MC3+. Its price and sonic claims had me intrigued. I arranged for a demo and though I went in skeptical the sonic difference was too significant to ignore. Transients were punchier in the lower and upper frequency ranges and the overall top end was smoother. It delivers all of the sonic characteristics you expect from the best clocks available but without the staggering cost. Needless to say, I sold my previous clock and switched to the MUTEC."

    "It took me a while, but the MC3+ sounds amazing. Never knew I missed out on so much details all these years: a big thank you!"

    "I have now integrated a third MC3+ in my playback system and the results improve with every additional clock. I own a very high quality, super high resolution sound system (big Avantgarde Acoustic horns among other equipment) that magnifies strengths and weaknesses of all components and enables me to audibly confirm the improvements in sound quality with every added clock."
Andy Norman
  • Andy Norman, UK
    "In conclusion, having the Mutec in the chain consistently improved the sound. In its current version it could well be worth a try in higher end systems or in systems where you suspect jitter could be an issue. I'm looking forward to Mutec implementing a USB capability using this technology as that will give us a real chance to put it through its paces."

    "My personal conclusion from the cascade experiment is that I now use three MUTEC MC3+'s clocks in my setup - and I will get myself a better DAC in the near future. Even with the Fireface UC, I experience a previously unknown music enjoyment I no longer want to do without thanks to the MC3+ cascade. Therefore, to conclude with a warning, re-clocking with the MC3+ has a high potential for addiction!"

    "The MC-1.2 USB-Interface alone was better than any other SPDIF I was able to look at, which didn't hit the level of Berkley Alpha USB ( $1,895 USD retail), but most of the ones below. Add the MC3+ and there was no contest the combo was hands down better."
