Merging NADAC MC-8

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.

NETWORKING

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, itwas 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 theaudiophile 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.

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!

REMOTE CONTROLLING MERGING+NADAC FROM ANY SMARTPHONE OR TABLET

If you use your MERGING+NADAC with a CD transport or any other device connected to the digital inputs, just connect your MERGING+NADAC to your Wifi hotspot to access it from any web browser like Safari, Internet Explorer, Chrome, etc… You can then control the main output level and the source selection.

THE MOST USUAL CONFIGURATION

Connect your MERGING+NADAC and your computer to the same switch or Wifi router and enjoy audio playback from that computer and remote control from any smartphone or tablet.
