Introduction to the NADAC
The NADAC Network Attached D/A Converter
The NADAC audiophile D/A converter has been developed from our professional high-resolution
D/A converter and shares the same technology. It was designed in Switzerland, where it is assembled and
tested to the same exacting standards as our professional products and is intended to deliver the same high
level of performance and reliability. It can accept PCM data at sample rates up to 384kHz and 24-bit resolution
and also DSD data, in DSD64, DSD128 and DSD256 formats. The NADAC
+NADAC can function as a stand-
alone D/A converter, but can also be connected to a network using Ethernet, where it can provide
considerable additional functionality and be remotely controlled via the network. The Ethernet interface is
exceptionally resistant to disturbances caused by RFI and EMI and has the additional advantage that cable
runs of up to 100m may be employed. It uses a professional protocol called RAVENNA to manage the data
transfer and this ensures a very high level of data integrity and a timing accuracy of 1 nanosecond.
Environmentally Friendly by Design
The NADAC has been carefully designed in order to keep power consumption to a strict minimum.
Merging Technologies believes in a sustainable future and takes appropriate measures at all phases of a
product's design and manufacture to avoid wasting energy. This said, we will never compromise on sound
quality and electronic components are carefully selected based on their audio performance first and foremost.
The side benefit is that if equipment runs cool it is usually also guarantee of longevity and long-term reliability.
Key Features
• Accepts 44.1kHz – 384kHz PCM at 24-bit resolution, DXD, DSD64, DSD128 and DSD256.
• SPDIF (RCA and Toslink) and AES/EBU inputs for conventional digital sources.
• Ethernet with RAVENNA interface allows asynchronous data transfer with computer audio systems and
allows cable runs up to 100m with Cat6 cable.
• Connects from the computer using standard ASIO on Windows and Core Audio on Mac.
• Multiple NADACs can be connected to the network.
• Web based remote control accessible via smartphone, tablet or computer.
• The remote allows control of volume level and source selection of any NADAC on the network.
• Front panel multifunction Rotary Control allows easy adjustment of volume level.
• The Rotary Control also provides access to a comprehensive and intuitive menu.
• Two front panel mounted headphone sockets enable connection without the use of adapters.
The NADAC: Two Versions
S T E RE O ( ST2 )
This employs an ESS Sabre ES9008S Reference D/A converter IC, which contains 8 individual D/A converters. In
the stereo unit 4 of these converters are merged to drive each output channel, providing improved linearity,
greater dynamic range and a lower noise floor.
M UL TI C HA NN E L-8 ( M C 8 )
In this version, each of the ESS Sabre ES9008S IC’s D/A converters drives an individual output channel. A
simple menu setting allows this unit to be configured to work as a stereo unit in exactly the same way as the
ST2 version, with the same advantages in performance.
