MERGING-CLOCK – Brochure 2018


Merging has recently shown a prototype version of the MERGING+CLOCK at audio fairs in Hong Kong and Denver. We will also be showing it in Darmstadt at Deutsche HiFi Tage 2018 on 3rd – 4th November and at Tokyo International Audio Show 2018 on 16th – 18th November. We anticipate shipping in time for Christmas. Primarily this product is designed to add to the existing range of MERGING+ products so it shares the same chassis, However, because this is an extraordinary product, we have provided additional outputs for use with other high end audio products or to provide Word Clock for professional users. There is an additional RAVENNA connection so that the CLOCK becomes the ultimate PTP Grand Master for the whole network when additional devices are added. There is a dedicated connector for MERGING+PLAYER or NADAC.
There are two versions of the MERGING+CLOCK. They both use instrument-grade crystal oscillators to achieve stability better than an atomic clock. The LN (Low Noise) version achieves a frequency stability of +/-25ppb which is remarkable enough, but the ULN (Ultra Low Noise) version achieves an unbelievable +/-10ppb. At least we believe so, but this is outside measurable limits!
The ULN version is dedicated to the audiophile who wants the ultimate clock, has the money to pay for it, and must have the absolute best.
We are confident the LN version already beats all other clocks on market. Our experts have been listening to both the ULN and the LN versions in very controlled conditions and they can confirm that there is a significant audible difference in both cases!


Merging is all about eliminating compromises but offering a choice to
meet different budgets. The MERGING+PLAYER offers fidelity and audio
quality that has left many critics in awe. The MERGING+POWER pushes
the envelope a little further by providing the optimum power conditions
for each circuit. The MERGING+CLOCK eliminates the last possible
performance compromise: The Master Clock.
>  MERGING+CLOCK gets you to the pinnacle of accuracy by employing
an instrument-grade crystal oscillator OXCO that is coupled to a Q
Damping System. This reduces the effects of any mechanical vibrations
that might be present in your listening environment. Merging offers a
choice of performance to match the budget and expectation.
The MERGING+CLOCK LN offers extraordinary accuracy with a
frequency stability of +/-25ppb but if the ultimate is your goal, the
MERGING+CLOCK ULN version offers the almost unbelievable figure of

>  Years of experience and research by Merging led to the discovery
of these critical points – short-term clock stability and phase noise
performance are exceptionally important for sound quality.
MERGING+CLOCK provides the state-of-the-art solution for digital audio
applications, which achieves 3E-13 grade short-term stability at sub-
second and as low as -120dBc at 1Hz offset (ULN). More important
than the technical specifications, the MERGING+CLOCK will stir the
emotions and touch your heart with the purity of the sound.
>  High-precision clocks are supplied by a number of manufacturers and
there are recognized standards for devices that are not part of a
network. The MERGING+CLOCK provides three different connection
types. The first is the RJ45 connector for RAVENNA/AES67 networks;
two 10MHz BNC connectors for other Hi-End components and BNC
Word Clock connectors for every sample rate from 44.1kHz to
1536kHz. That is 32 times 1FS!
