Network Attached Digital to Analogue Converter
The first 384kHz, DSD256, multichannel and open standard network attached DAC, NADAC by Merging Technologies presents the same technology deployed in the recording, mixing and mastering of music program. Now the discerning listener can enjoy the same unrivalled specifications and optimum linearity experienced by the artist, producer and engineer in the control room.
As is the case with the Merging Technologies tools used by music production engineers, the listener can now experience the liberation and networking capability of RAVENNA; a layer3 IP based protocol. The major advantage of networked operation is the removal of cable length restrictions and allowing genuine multi-room and multi-zone operation, all controllable from a single location and using standard components and cabling. Being a ‘mission critical protocol’ RAVENNA has been designed to ensure immensely low jitter rates and latencies (sub-millisecond) and reliably ensures that every single sample gets to where it needs to go without fail.
NADAC is presented in two formats; stereo, and multi-channel-8 for surround sound applications. Analogue outputs are balanced on 3-pin male XLR and unbalanced RCA Phono connectors. Separate headphone sockets are provided on ¼” jack and min-jack with uncompromised quality and ability to connect a different source than the main output with separate volume control.
Digital inputs are Ethernet (RAVENNA / AES67) on RJ45 connecter, with support for 44.1kHz – 384kHz PCM, DXD, DSD64/128/256 being standard. Communication with the computer is provided using ASIO on Windows and CoreAudio/DoP on MacOS allowing for multi-sources and multi-zones from any standard applications such as Roon, JRiver, iTunes etc. Ultra-precise communication clocking driven by the DAC through IEEE 1558 Precision Time Protocol is provided ensuring a clock resolution of one nanosecond. Input connectivity includes AES/EBU on 3-pin female XLR connector (44.1kHz-192kHz), SPDIF Optical on Toslink connector (44.1kHz-96kHz), SPDIF Coaxial on RCA Phono (44.1kHz-96kHz), Wordclock and DC Power Supply.
So let’s summarize the benefits of NADAC:
