Connecting Merging+NADAC with PC through the RJ45 port
How can I connect Merging+NADAC with my PC through the RJ45? My PC has only one RJ45 port. If I were to install a net card, would it work?
You can connect Merging+NADAC directly to the PC RJ45 port and install the ASIO driver on your PC. If you need to connect your PC to another device with the same port, just use a standard switch. Merging Technologies has a list of recommended switches at http://nadac.merging.com/support.
What is the Merging NADAC’s output impedance?
What is the NADAC's output impedance?
The NADAC-MC8's Output impedance is of 90 Ohms (Differential), equivalent to 45 Ohms (Single-ended) in 8 channel mode and about 53 Ohms (Differential), equivalent to 26.5 Ohms (Single-ended) in Stereo mode.
The NADAC-ST2's Output impedance is always of 90 Ohms (Differential), equivalent to 45 Ohms (Single-ended).
In terms of feeding power amps directly from the Merging NADAC, what would be the lower limit of impedance it can drive?
In terms of feeding power amps directly from the NADAC, what would be the lower limit of impedance it can drive?
Merging has tested it to work (at full specs) down to 300 Ohms (with Audio Precision) but it can even drive loads with a much lower impedance than that. We've had reports that it can even drive a zero Ohm load (equivalent to a short circuit) when set to +12 dBu (Low) and within about 1 dB of full scale output when set to 18 dBu (High).
Can the Merging NADAC DA outputs be calibrated independently, per channel?
Can the NADAC DA outputs be calibrated independently, per channel?
Yes this is possible from the NADAC Trim/Polarity option located under the Main menu. The Trim levels are individual and can be used for calibration (e.g. for a Surround setup). Note that the Trim Level settings are carried in Digital form.
How is the Merging NADAC Main max level option handled in the System Menu?
How is the NADAC Main max level option handled in the System Menu?
The Main Max Output Level setting option is carried in Analog form:
- High = + 18 dBu (on XLR balanced output), + 8 dBu (on RCA Unbalanced output)
- Low = + 12 dBu (on XLR balanced output), + 2 dBu (on RCA Unbalanced output)
Can Merging NADAC Main outputs and Headphone play files at different sampling rates ?
Can NADAC Main outputs and Headphone play files at different sampling rates ?
No, NADAC can only handle one sampling rate at a time. All outputs have to run at the same sampling rate.
What is the maximum length of the network cable for Merging NADAC?
What is the maximum length of the network cable?
100 meters - 328 ft for CAT5E or CAT6 cables.
Users with a need to extend their connections beyond 100 meters may take advantage of copper to fiber converters, which further extend the reach to 650 meters with multi-mode fibers and even several kilometers with single-mode fibers.
Which network cable can I use with Merging NADAC?
Which network cable can I use with NADAC?
CAT5E, CAT6 or higher copper cable, unshielded.
Is Merging NADAC compatible with any network switch or router?
Is NADAC compatible with any network switch or router?
NADAC uses the RAVENNA protocol, which is an open standard for real-time media over IP. As such it can be deployed on any Ethernet Network, be it 10 Mbits, 100 Mbits or 1 Gigabit based.
However in order to provide adequate bandwidth for High channel count upto and including the ultra high sampling rates offered by NADAC, Merging requires switches capable of handling 1GbE connections. Furthermore the performance of a RAVENNA system improves with the quality of the network infrastructure, so it is highly recommended to use Managed switches with the capacity to be configured adequately for QoS (Quality of Service).
Is Merging NADAC compatible with DLNA and UPnP devices?
Is NADAC compatible with DLNA and UPnP devices?
NADAC is not a uPnP or DLNA enabled device, it requires drivers to be installed on connected computers to communicate with it. Both ASIO driver for Windows and CoreAudio driver for MacOS are available here. Once installed NADAC will behave like any USB DAC, with all the advantages of Ethernet Networking in addition.
