Modifications and Configurations of the Console

We should mention that the same retail versions of Xbox 360 may differ a little depending on a region. For example, European versions of the Xbox 360 include a 5M RCA adapter (component connection) for the popular European connector SCART. And Xbox 360 for Australia and New Zealand lacks a headset for voice communication with other owners of the Xbox 360.

When the sales began, Microsoft offered two modifications of the Xbox 360:

Xbox 360 (Premium System or Premium Package)

A more expensive bundle that already includes a number of accessories to be sold separately.




Bundle
  • Xbox 360
  • HDD for Xbox 360 (20 GB; 13 GB of them are available to users)
  • A single wireless gamepad with an adapter for two AA batteries
  • Component HD AV cable (1 Xbox 360 Multi AV Out — 5M RCA Video + 2M RCA Audio + 1 S/PDIF Out)
  • Wireline headset for Xbox Live! services
  • LAN cable (Ethernet)

The main functional difference of the more expensive Xbox 360 is its backward compatibility with the Xbox right "in the box", you don't have to buy a HDD.

Exterior of the more expensive Xbox 360 can be distinguished by a chromium-plated DVD tray.

Xbox 360 Core System

A more affordable bundle without practically all accessories in order to drop the retail price.


Bundle
  • Xbox 360
  • A single wireline gamepad (3-meter cord)
  • Composite AV cable (1 Xbox 360 Multi AV Out — 1M RCA Video + 2M RCA Audio).

Here are the main functional peculiarities of the Xbox 360 Core System:

  • No backward compatibility with "boxed" Xbox — you can get it by purchasing Xbox 360 HDD
  • No way to output HDTV — you will have to buy one of HDTV cables (component or VGA)
  • No way to store user settings, profiles, and game saves — you should either add Xbox 360 HDD, or Xbox 360 Memory Unit.

You can identify a cheap modification of the Xbox 360 by a while plastic DVD tray.

Additional equipment
