System Requirements
The TX-NR900/900E is a network audio client that is connected via
a LAN to a PC and allows you to enjoy music files saved on the PC,
as well as Internet radio, from anywhere in your home.
Internet radio features
The TX-NR900/900E provides enhanced support for Internet radio and
allows you to:
• Listen to both WMA and MP3 audio streamed from Internet radio
stations
• Select stations by genre, location, or language
• Preset up to 30 Internet radio stations
Net-Tune Features
The Net-Tune Central is software which distributes music files stored on
PC through LAN to the TX-NR900/900E.
The TX-NR900/900E plays distributed music data whenever you need.
* This software is available from Onkyo’s web
US → http://www.onkyousa.com/net-tune/
Europe → http://www.onkyo.net/net-tune
Japan → http://www.onkyo.co.jp/
Asia, Oceania, and Central and South America
→ http://www.onkyo-intl.com/
In the connection between the Net-Tune Central and the TX-NR900/
900E, the standard TCP/IP network protocol and the Onkyo’s
proprietary NTSP protocol is used for music distribution through LAN.
The NTSP protocol handles not only data for music itself but also
additional music information including the name of tracks and artists,
enabling high usability.
In addition to the music distribution server function, the Net-Tune
Central can automatically retrieve the music files stored on PC to register
them easily with the Net-Tune Central database.
The Net-Tune Central supports WAVE (PCM), MP3 and WMA formats.
The WAVE format has high sound quality (equivalent to CD) with no
compression. The MP3 format is widely used through Internet
environment and has near-CD quality with compression. The WMA
format is developed by Microsoft
®
has also near-CD quality using higher
compression rate.
Editable music library
With the Net-Tune Central software, you can edit music titles, artist
names, genre names, and so on, while you can also create new genre
names, for all music files saved on the PC’s hard disks.
The Net-Tune Central also provides this information with the TX-NR900/
900E, allowing you to select tracks easier on the TX-NR900/900E.
Hint:
File Format: MP3/WMA (Approximately 1 MB for 1 minute)
WAVE (Approximately 10 MB for 1 minute)
* How much free space is actually required also depends somewhat on
such factors as the format and reserved space of your hard disk, and
the bit rate at which you make recordings.
* Depending on the MP3 encoder you use, your recorded file may not
be playable, or can play the music degraded by noise, or can
generate uncomfortable sound.
Also note that no WMA format file with copyright protection
enabled is playable on the TX-NR900/900E.
Requirements for listening to both Internet radio stations
and music files saved on the music server
■ Modem (a device that provides Internet connections via leased lines;
e.g., a cable modem, xDSL modem, terminal adapter)
* To have access to Internet, you typically need to make a contract
with an Internet service provider (ISP). Modem requirements differ
from ISP to ISP; for detailed information, consult with your ISP or
PC retailer.
■ Router (gateway) (a device that enables multiple PCs or devices to
connect to the Internet simultaneously)
An IP address can be obtained automatically by using the router’s
DHCP function.
* Some routers have built-in modem functionality. Router
requirements differ from ISP to ISP; for detailed information,
consult with your ISP or PC retailer.
■ Ethernet CAT-5 cable
■ Minimum Internet Connection Requirements:
• Broadband Internet Connection
• DHCP (Dynamic Host Configuration Protocol) based network
(requires a DHCP-enabled router)
• 100Base-TX switch built-in broadband router (recommended)
■ Minimum PC System Requirements:
600 MHz Intel Pentium III CPU or better, Windows 98SE, Me, XP,
or 2000 OS (operating system), more than 20 MB of free hard disk
space, RAM (Windows 98SE, Me, 2000; requires 128 MB, XP;
requires 256 MB) and Ethernet port.
Not compatible with Macintosh systems.
Notes:
• If your ISP contract assumes manual configuration of network
settings, you need to manually configure your network settings as
described in “Network Setup Menu” (see page 6).
• The TX-NR900/900E does not support network settings for PPPoE
connections; if your ISP contract requires PPPoE, therefore, you
must have a gateway/router with PPPoE support.
• You may have to set up a proxy server to listen to Internet radio,
depending on the ISP you choose. If your PC is configured to use a
proxy server for Internet access, the TX-NR900/900E must also be
configured the same way. For more information, see “5-2. Proxy
Setup Sub-menu” (see page 7).
• The TX-NR900/900E is designed to take advantage of the DHCP
and AutoIP functionality, thereby automatically configuring the
network settings. If you opt not to use the DHCP and AutoIP
functionality, you should manually configure the network settings.
For more information, see “5-1.IP Address Sub-menu” (see page 7).
• To enjoy music on Internet Radio, it is assumed that you provide a
broadband Internet connection on which you can successfully run a
web browser. If you have any problem in connecting to the Internet,
consult with your ISP.
