Helpful Tips

ü
Although the headphones will continue to operate on low battery power, the performance will
degrade as the batteries begin to drop in voltage.
1. You sense that the sound is dropping out more often than usual, or...
2. The sound is distorting, regardless of the volume levels, or...
3. The headphone power light is constantly on rather than flashing.
ü
If the sound is distorted when using the transmitter analog input, it may be that the audio
source is overloading the X4 analog inputs. Try turning down the volume on the transmitter
to reduce the input sensitivity, then turn up the headphone volume to a comfortable level.
Note that the transmitter volume control has no effect on the digital input.
ü
Standing too close to the transmitter can cause the IR signal to overload the headphones,
which will mute the sound. For best performance, stand at a distance between 4' and 30'
from the transmitter.
ü
The transmitter analog inputs will automatically shut off whenever the digital input is active.
To hear the analog input signal, either disconnect the optical cable from the digital input on
the transmitter, or shut off the device connected to the optical cable (e.g. Xbox) to disable
the digital audio signal.
ü
Don't wear the headphones with the headband behind your head. The headband must be
positioned on top of your head to optimize the surround sound effect.
ü
Don't cover the headphone IR sensors with your hands or hair.
ü
Don't use the system in areas exposed to direct sunlight or strong light or the IR signal may
be reduced, causing the sound to be interrupted.
ü
Be sure to position the mic so that the jack indicator is facing your mouth. Or, remove the
foam cover and check that the holes in the mic case are facing your mouth.
ü
Switching the power button on and off repeatedly may cause the transmitter to not power up
correctly. If this happens, turn off the transmitter power, wait a few seconds, then turn it on
again so that it may reset properly.
Using the X4 with Plasma TVs
Some plasma TVs generate infrared (IR) interference at the same frequencies used by the X4
transmitter. This IR interference can be picked up by the X4 headphones as a background
"buzz" or "crackling" sound. This is not unique to the X4 headphones--
headphones can exhibit this problem with plasma TVs
The plasma IR interference is most noticeable when there is no audio playing through the X4
transmitter, such as when the Xbox game menu is displayed or just before the game begins.
Once the game sound begins, the X4 IR transmitter signal will overpower the plasma IR
interference so the plasma generated noise in the headphones is eliminated.
Plasma IR interference decreases as you move further away from the screen. So it may be
more noticeable if your TV is located in a small room and you're sitting closer to the TV screen.
Also, if the X4 transmitter is placed too low, too high or too far to the side of the plasma screen,
the X4 IR signal will be reduced because it is not in direct line-of-sight with the headphones. As
a result, the plasma IR interference signal may be stronger than the X4 IR signal, resulting in
plasma IR noise in the headphones.
To minimize or eliminate the plasma IR interference, it is important to maximize the X4
transmitter IR signal intensity and minimize the plasma IR interference signal. This may be
accomplished by standing further away from the plasma TV screen and placing the transmitter
either in direct line of sight with the headphones, or closer to the headphones.
