Network Audio Adapter (NAA)
Extremely high-resolution music is normally delivered to the SDV 3100 HV by
the direct route via a USB connection between the audio workstation (Audio
PC) and the SDV 3100 HV. However, since USB connections are limited to a
maximum length of 3m the Audio PC must be set up in the immediate vicinity
of the SDV 3100 HV.
In installations where the distance between PC and SDV 3100 HV is greater
than this, what is known as a Network Audio Adapter is required, and the
SDV 3100 HV incorporates this facility. This technology makes it possible to
convey extremely high-resolution music files on the network: up to PCM768
and DSD1024. The Audio PC can then be installed in any location in the
house.
Hardware and software
requirements
In addition to the SDV 3100 HV you will need a high-performance Audio PC, a
GigaBit network router, a LAN connection between the Audio PC and the
SDV 3100 HV and “HQPlayer” software from the Signalyst company. A copy
of “roon-Server” software from the roonlabs company can also be installed
on the Audio PC to help you manage your music archive; it also provides a
convenient means of controlling the entire system.
More information on HQPlayer and roon software can be found on the
Internet at:
https://www.signalyst.com/consumer.html
and

Since the transmission of ultra-high resolution music data using what is
known as isochronous transfer mode requires data transfer at rates of up to
300 MBit per second with total immunity to interruption, all network
components involved in the signal transfer must guarantee completely
interference-free data transfer.
It therefore follows that it is not possible to use WLAN, or a 10 or 100 MBit
LAN network, for this purpose. It is also necessary to isolate the audio
network from the rest of the home network, so that other network traffic
cannot interrupt or interfere with the audio data transmission. For details on
connections please see the Wiring diagram in Appendix A.
Select the NAA input (Network Audio) on the SDV 3100 HV.
(it may be necessary to activate the input beforehand in the System
Configuration menu. Please refer to the section entitled “Basic settings
of the SDV 3100 HV”).
Start HQ Player on the Audio PC.
In HQPlayer select “NetworkAudioAdapter” as Backend under
File/Settings.
In HQPlayer select “TA-NetworkAudio:DAC SDV 3100 HV: USB Audio”
as Device under File/Settings.
In HQPlayer select “None” as SDM Pack under File/Settings (this
enables native DSD transmission).
Complete the remaining settings in accordance with the characteristics
and capabilities of your Audio PC, then confirm with “OK” and leave the
Settings menu.
If you now select a track in the HQPlayer control window, it should be
audible via the SDV 3100 HV.
