Turtle Beach X4 Manuel D’Utilisation

The Ear Force X4 Dolby surround sound gaming headphone system uses an infrared
signal to transmit wireless game audio from the XBOX 360 to the X4 wireless
headphones. The X4 transmitter uses Dolby Headphone technology to produce a
more realistic game experience by recreating the sound of a 5.1 channel speaker
system with the X4 stereo headphones. The X4 incorporates the following features
designed specifically to enhance Xbox 360 gaming:

Dolby Digital, Dolby Pro Logic II and Dolby Headphone processing technology.

Digital and analog inputs for listening to the XBOX and other audio sources.

High powered IR beam covers a wide reception range for freedom of movement

during game play.

Large, soft ear cushions and lightweight design for optimum comfort during long

gaming sessions.

Chat Boost automatically adjusts Xbox Live chat levels during loud game play.

Microphone monitor lets you hear what you’re saying.

Bass boost enhances deep game sounds.

Independent volume controls for balancing game and chat levels.

Automatic power-off function turns off the headphones after a period of no sound to

conserve battery power.
