Net-Tune
 
The TX-NR901 can be used as a Net-Tune client on a 
standard Ethernet network. By installing Onkyo’s Net-
Tune Central server software on your computer, you can 
play all of your MP3, WMA, and WAV files through the 
TX-NR901. If your network is connected to the Internet, 
you can also tune into Internet radio stations.
 
Internet Radio
 
With Internet radio you can:
• Listen to stations that use MP3 or WMA format 
streaming.
• Select stations by genre, location, or language.
• Preset up to 30 Internet radio stations.
 
Net-Tune
 
For audio delivery over Ethernet, Onkyo developed 
NTSP (Net-Tune System Protocol). Since it’s based on 
the industry standard TCP/IP protocol, it’s efficient and 
very responsive.
You can download Onkyo’s Net-Tune Central server 
software from the following Onkyo Web sites:
 
America: 
 
http://www.onkyousa.com/net-tune/
 
Europe:
 
 http://www.onkyo.net/net-tune/
 
Japan:

Asia, Oceania, and Latin America:

Net-Tune Central searches your PC’s hard disk for music 
files and creates a music database automatically, making 
it very easy to set up. Net-Tune clients, including the 
TX-NR901, can then play music in the database.
Net-Tune Central supports the following file formats, 
and sampling rates of 32 kHz, 44.1 kHz, and 48 kHz.
 
WAV:
 
 high-quality, uncompressed, linear PCM.
 
MP3:
 
 high-quality, compressed, small file size.
 
WMA:
 
 high-quality, compressed, smaller file size 
than MP3, developed by Microsoft. (Protected WMA 
files cannot be played.)
Before you download Net-Tune Central, you’ll be 
prompted to enter the serial number printed on the rear 
of your TX-NR901. Depending on your Internet connec-
tion, it may take 10 or more minutes to download.
 
Net-Tune Central Editing Functions
 
With Net-Tune Central you can edit the titles, album and 
artist names of your MP3, WMA, and WAV files, and 
create and edit genre names. In addition, you can make 
playlists of your favorite tracks.
 
Computer Requirements
 
The computer requirements necessary for running the 
Net-Tune Central server software are as follows:
 
Operating system:
 
 Windows 98SE, Me, XP, or 2000. 
(Mac OS not supported.)
 
Processor:
 
 Intel Pentium III, 600 MHz or higher
 
Memory:
 
 128 MB (Windows 98SE, ME, 2000) 
256 MB (Windows XP)
 
Display:
 
 800 x 600 pixels or higher, High Color
 
LAN/Ethernet network port
 
 
Sound capabilities
 
 
Hard disk:
 
 At least 20 MB for Net-Tune Central
Obviously you’ll need space to store your music files. 
MP3 and WMA uses approximately 1 MB per minute, 
while WAV uses approximately 10 MB per minute, 
although this will depend on the sampling rate and bit 
rate that you use. MP3 files made using certain encoders 
may not be playable, or may be noisy when played.
 
Network Requirements
 
 
Ethernet Network
 
The TX-NR901’s Ethernet port supports 10Base-T. For 
best results, a 100Base-T switched Ethernet network is 
recommended. Although it’s theoretically possible to use 
a wireless network, due to unpredictable performance, it 
may not provide satisfactory results, so a wired network 
is recommended.
 
 
Ethernet Router
 
A router manages the network, routing data and supply-
ing IP addresses. Your router must support the following:
• NAT (Network Address Translation). NAT allows sev-
eral networked computers to access the Internet simul-
taneously via a single Internet connection. The 
TX-NR901 needs Internet access for Internet radio.
• DHCP (Dynamic Host Configuration Protocol). 
DHCP supplies IP address information to network 
devices, allowing them to configure themselves auto-
matically.
• A router with a 100Base-TX switch built-in is recom-
mended.
Some routers have a modem built-in, and some ISPs 
require you to use specific routers. Please consult your 
ISP or computer dealer if you’re unsure.
 
 
CAT5 Ethernet cable
 
Use a standard CAT5 Ethernet cable (straight-type).
 
 
Internet Access (for Internet radio)
 
To use Internet radio, your Ethernet network must have 
Internet access. A narrowband Internet connection (e.g., 
56K modem, ISDN) will not provide satisfactory results, 
so a broadband connection is strongly recommended 
(e.g., cable modem, xDSL modem, etc). Please consult 
your ISP or computer dealer if you’re unsure.
