HAS BEEN RECENTLY SENT IN TO MERGING FOR THE MOST CURRENT FIRMWARE/SOFTWARE UPDATE!

MERGING+NADAC was born out of the repeated request from Merging’s mastering and recording engineer customers to provide a DAC for the audiophile market. This would be for their own customers, the music lovers, the high-resolution lovers, the purity lovers, a DAC able to reproduce the same experience, the same transparency they, as engineers, enjoyed in their studio when working on their Masters.

The universally acclaimed sound quality, transparency and precision of the Horus and Hapi professional converters was something these engineers were dying to offer to the people who were purchasing their music, their chef d’oeuvre.

We carefully listened and designed MERGING+NADAC based on the Horus and Hapi architecture and principle, but with a lot of improvements expected by the audiophile market, like channel summing, dedicated headphone DA, unique ergonomics and of course a superb aluminum chassis.

Not only did we deliver state of the art music listening in an audiophile environment, but also introduced some radical design enhancements to MERGING+NADAC, like tablet and smartphone remote control as well as some of the recipes which made Horus and Hapi such a great success and revolutionary in their own market. Most notably, the network audio communication through RAVENNA. You will find below some details about the benefits of this technology.

NETWORK ATTACHED DIGITAL TO ANALOG CONVERTER
Nice acronym, but what is it all about? The modern world has become dependent on networks and the technology has been designed to be reliable and scalable. As the network capacities have increased, the possibility of using IP networks for video and audio became an obvious choice. Clearly Gigabit Ethernet had sufficient capacity for high quality audio but it was not optimal without an additional protocol adding the required precision and management. Merging needed to move away from the PCIe technology that had served us well for many years and we looked at alternatives that could offer sufficient accuracy and reliability with high channel counts and Hi-Res Audio data rates. Other IT based point-to point connections such as USB or Firewire were either not optimum or obsolete for audio even though other manufacturers had pressed them into service. There was only one choice that made sense: RAVENNA.

RAVENNA

This open and published IP network technology had been created to meet the demands of national broadcasters and focused on essential requirements of extremely accurate clocking, high resistance to packet loss and very low latency. Initially it did not encompass high PCM sampling rates and certainly not DSD. However, it was not difficult to make changes to allow that, so Merging worked closely with the developers to make sure that sufficient channels at up to DSD256 could be handled with an accuracy that exceeded anything previously available. It remains the only logical choice for the professional and the audiophile and is now available in MERGING+NADAC. The added bonus to using an advanced networking solution is being able to send and receive control information as well as audio data. This opened up exciting possibilities in the studio and now you can enjoy these same benefits in your own home.

COMPATIBILITY
The RAVENNA protocol comes with absolutely standard drivers for any computer operating system. ASIO for Windows, CoreAudio with DoP support for MacOS. As easily installed and configured as any other driver for USB or Firewire, the MERGING+NADAC RAVENNA driver allows use of any application of your choice to playback your music files, Emotion, JRiver, Audirvana, iTunes, etc... as well as any music server or streamer able to communicate through those standard ASIO or CoreAudio drivers.

NETWORK CONFIGURATIONS
So, what is this network story about and what does it allow for ?

Better that any pontificating sentences and technical explanations, some drawings will simply illustrate the most common applications and scenarios that can be achieved with MERGING+NADAC in a networked environment !

PEER TO PEER CONNECTION TO A COMPUTER OR SERVER
Just plug a cat5e or cat6 cable between the MERGING+NADAC and any computer, music server or streamer and send audio to the MERGING+NADAC from your favorite application through the standard ASIO or CoreAudio driver. As soon as the playback application is running on the computer it will appear in the MERGING+NADAC source selection menu, exactly like any internal digital input. Select it... et voilà!
