n Broadband Internet connection
A broadband line connection to the Internet is required in order to 
use the AVR-4308’s Internet radio function and firmware update.
n Modem
This  is  a  device  that  is  connected  to  the  broadband  line  to 
communicate  with  the  Internet.  Some  are  integrated  with  the 
router.
n Router
• When  using  the  AVR-4308,  we  recommend  you  use  a  router 
equipped with the following functions:
·  Built-in DHCP (Dynamic Host Configuration Protocol) server
  This function automatically assigns IP addresses on the LAN.
·  Built-in 100BASE-TX switch
  When connecting multiple devices, we recommend a switching 
hub with a speed of 100 Mbps or greater.
• When using with a wireless LAN, prepare a broadband router with 
built-in access point.
n Ethernet cable (CAT-5 or greater recommended)
Use for wired LAN.
• The AVR-4308 does not come with an Ethernet cable.
• Some flat type Ethernet cables are easily affected by noise.
  We recommend using a normal type cable.
• For the Ethernet cable, used a shielded twisted pair (STP) cable.
  Do not use an unshielded twisted pair (UTP) cable, as it may exceed 
noise standard limits.
n Computer
A computer with the following specifications is required to use a 
music server:
• OS
  Windows
®
 XP Service Pack2, Windows Vista
• Software (Prepare one of the following.)
·  .NET Framework 1.1 and Windows Media Connect (Windows XP)
·  Windows Media Player ver.11
·  DLNA-compatible server software
• Internet browser
  Microsoft Internet Explorer 5.01 or later
• LAN port
• 300 MB or more free disk space
b Free  disk space is required to store music and video files. The 
following sizes are approximate.
Format Bit rate Per minute Per hour
MP3 / WMA

NOTE
• A contract with an ISP is required to connect to the Internet.
  No  additional  contract  is  needed  if  you  already  have a  broadband 
connection to the Internet.
• The types of routers that can be used depend on the ISP. Contact an 
ISP or a computer shop for details.
• Depending  on  the  server,  video  files  may  be  displayed,  but  they 
cannot be played on the AVR-4308.
For  connections  to  the  Internet,  contact  an  ISP  (Internet  Service 
Provider) or a computer shop.
n Others
• If you have an Internet provider contract for a line on which network 
settings  are  made  manually,  make  the  settings  at  GUI  menu 
“Manual Setup” – “Network Setup” (vpage 33 ~ 35).
• With  the  AVR-4308,  it  is  possible  to  use  the  DHCP  and  Auto IP 
functions to make the network settings automatically.
• When  using  a  broadband  router  (DHCP  function),  the  AVR-4308 
sets the IP address, etc., automatically.
  When using the AVR-4308 connected to a network with no DHCP 
function, make the settings for the IP address, etc., at GUI menu 
“Manual Setup” – “Network Setup” (vpage 33 ~ 35).
• The AVR-4308 is not compatible with PPPoE. A PPPoE-compatible 
router is required if you have a contract for a line of the type with 
which the PPPoE is set.
• Depending on the ISP with which you have your contract, it may 
be  necessary to  make  proxy  server  settings  to  use  the  Internet 
radio function. If you made proxy server settings on the computer 
to connect to the Internet, make the proxy server settings on the 
AVR-4308 in the same way.
Turn clockwise.
