Digital Input LED: This LED turns on when a digital input signal is
detected. When this LED is ON, the analog input is turned off.
Surround Sound LED: The LED will light whenever the digital input is
being processed by the surround sound decoder. When this LED is
off, the audio signal will be heard in stereo.
Dolby® Digital LED: The LED will light whenever a Dolby Digital
encoded signal is detected on the digital input.
Power/Link LED: When the transmitter is powered on and
communicating with the headset, this LED will be on solid. When
the headset is turned off, the LED will turn off. A slowly pulsing LED
indicates that the transmitter can’t communicate with the headset.
This could happen when the headset is out of range, turned off or not
paired with the transmitter. (see pg. 6)
Digital Input and Output: Connect the digital input to the Xbox 360
digital output using the included digital optical cable. The digital input
is passed through to the digital output so you can connect the XP400
transmitter and your home theater system to hear the Xbox sound on
the headset and speakers at the same time. When a digital signal is
detected by the optical input, the Digital Input LED will be lit.
Analog Input Jack: Provides a 3.5mm input for digital music players or
additional audio sources. (3.5mm cable sold separately)
NOTE: The analog input is deactivated whenever a digital input is active, so
both the digital and analog inputs cannot be used at the same time.
Pair Button: Press and hold to activate pairing mode. (See pg. 6)
Surround Sound Angles Button: Press to select different HRTF
surround angles. (see pg. 14)
Surround Sound On/Off Button: Pressing this button toggles between
surround sound and stereo sound. When surround sound is active,
the Surround Sound LED will be lit.

Using the Transmitter

Transmitter Range
The transmitter sends game audio from your Xbox 360® to the headset
via digital radio frequency (RF) signal, so a direct line of sight is not
required. When you’re out of range, you may hear popping or clicking
sounds if the headset loses the RF signal. For best performance,
place the transmitter in an open area that is unobstructed by objects
that might absorb RF signals from the internal antenna. Avoid placing
it on a metal surface, such as the top of a home theater A/V receiver.

Pairing the Headset and Transmitter

The headset and transmitter in this package are “paired”, which means they’re synchronized to ensure they work together. When
the headset and transmitter are communicating, the POWER LED on the the transmitter will be on solid. If this LED is slowly pulsing
instead, it means the transmitter can’t communicate with the headset. This could happen when the headset is out of range, not turned
on or not paired with the transmitter. If the LED is slowly pulsing when the headset is on and within range, then they might need to be
“paired” as described below:
NOTE: Only one headset can be paired with the transmitter. If you pair two headsets with the same transmitter, they’ll interfere with each other
as they compete for the transmitter RF signal. This will cause one headset to shut off. So don’t try to pair two headsets with the same transmitter!
2 feet
Maintain a distance of at least
2 feet between the headset and
transmitter when pairing.
1. Make sure the headset and transmitter are turned off and
they are at least 2 feet away from each other.
2. Power on the transmitter by connecting it to a free USB
port on your gaming console. Then press and hold the
PAIR button on the transmitter. The transmitter LED will
begin to flash rapidly, then release the PAIR button.
3. Press and hold the headset POWER button for about 6
seconds until the LED begins to flash rapidly, then release
the button.
4. Wait for the headset and transmitter to pair. This process
could take up to 30 seconds.
If pairing is successful, the LED on the transmitter should be
on solid and the headset LED should be flashing about once
per second, indicating that the units are paired.
If pairing fails, repeat steps 1-4. It may take up to 5 attempts
to pair successfully.
Optimum range: within 30 ft.
