The X41 uses Dolby Pro Logic
®
IIx, Dolby Digital, and Dolby Headphone surround pro
-
cessing technologies, the industry-standard formats for encoding multi-channel game
audio. Dolby Headphone processing recreates 7.1 channel surround sound using the
X41 stereo headset so you can hear the sound all around you, as if you were listening
to a 7.1 speaker system.
The transmitter supports three types of digital source material and analog stereo.
When the Bypass button is ON, Dolby processing is defeated, so you can hear the un
-
processed input signal in stereo, as it sounds from the source. Here’s how the signal
processing modes operate:
• When the digital input signal is active, the front panel digital LED turns on and the
analog inputs are turned off. You do not have to disconnect cables to switch be
tween analog and digital sound sources.
• If the Bypass LED is on, Dolby processing is defeated and the signal will be heard
as stereo.
• If the digital input is a Dolby Digital 5.1 or 7.1 channel signal, the front panel
LED turns on and Dolby Headphone processes the channels to create surround
sound in the headset.
• If the digital source is a Dolby Pro Logic IIx signal, both Dolby LEDs will turn on and
Dolby Headphone creates Pro Logic IIx surround sound in the headset.
• If the digital input is stereo, the LED turns on and the signal is processed
by Dolby Headphone to create an expanded stereo sound in the headset.
• If the digital input is not active (or is disconnected) the analog stereo signal will be
active.
• If there is an analog stereo input and the Bypass LED is on, there will be no Dolby
processing and the signal will be heard as stereo.
• If there is an analog stereo input and the Bypass LED is off, the front panel
LED turns on and the analog stereo signal is processed by Dolby Pro Logic IIx and
Dolby Headphone to create an expanded stereo sound in the headset.
