10) C t r. Allows adjustment of the center speaker’s
level relative to that of the front left and right. To use,
p r ess the button until the indicator LED lights. Use the
volume pads to raise or lower the center chanel level
until you get the balance that you want. The central
display will show how much boost or cut you have
applied, in decibels (dB). Pressing the button again
until the LED goes out will lock the setting and re t u r n
the volume pads to master mode, controlling overall
level. To re t u r n to the original setting, just turn the con-

1 1 ) Mute. Tu rns the sound on and off. When the sys-
tem is muted, the LED above the button will light.
1 2 ) Mode Indicator LEDs. At the top of the contro l
module, there are three mode indicator LEDs. When
no LED is lit, stereo decoding is taking place. When
the incoming signal is decoded in 5-channel stere o
the "5 CH Stereo" LED will be lit. The "PLI I" LED will
be lit when Pro Logic II movie mode decoding is tak-
ing place. When the "Dolby Digital" LED is lit, the
GMX is receiving and decoding a Dolby Digital bit-
s t r eam. On Dolby Digital 2.0 signals, 5-channel
s t e r eo and Pro Logic decoding can be applied. If one
of these post-processing modes is applied, the appro-
priate LED will be lit in conjunction with the "Dolby
Digital" LED.
Choosing the Right Sur round
Mode
The GMX D-5.1 offers five surround modes,
selected via the Surround button on the
GMX control module:
• Dolby Digital. This is a discre t e - c h a n -
nel digital mode that allows 1- to 5.1-
channel re p r oduction. (The channels
a r e left, center, right, left surro u n d ,
right surround, and low-fre q u e n c y
e ffects.) The system automatically
engages Dolby Digital decoding
when it receives a Dolby Digital sig-
nal at one of its digital inputs. It is not
available with any other sort of signal
or when the analog input is selected.
The Dolby Digital decoder will configure
itself automatically according to the input
signal. From one to five satellites and the
subwoofer will be active.
• S t e reo. This is the standard mode for the analog
input and for two-channel signals received at a digi-
tal input. Only the front left and right satellites and the
subwoofer are active.
• 5-Channel Stere o . Available for all inputs re c e i v i n g
analog or two-channel digital signals. It re d i s t r i b u t e s
a stereo signal across the five satellite speakers to give
v e ry broad, even coverage. All five satellites and the
subwoofer are active.
• Dolby Pro Logic II. Available for all inputs re c e i v-
ing analog or two-channel digital signals. This mode
p r ovides accurate decoding of Dolby Surro u n d -
encoded signals and natural, realistic five-channel
enhancement of stereo signals. All five satellites and
the subwoofer are active. Dolby Pro Logic II has two
s u b - m o d e s :
Cinema (Red LED) - Select for sources that have
been encoded in Dolby Surro u n d . This includes
many games, TV programs, and movies on video.
Music (Green LED) - This mode is especially appro-
priate for stereo music, to which it adds a very
appealing sense of spaciousness and depth.
SWS Link
On the back of the GMX D-5.1’s subwoofer is a jack
labeled "SWS Link," a special port for attachment of
one or more Klipsch ProMedia SWS powered sub-
woofers. This port enables full integration of SWS
subwoofers into the GMX system. Although the GMX
D-5.1 provides good bass output on its own, one or
m o r e SWS subwoofers will add both depth and
power to your system’s bottom end. The Klipsch
P r oMedia SWS subwoofer system is available for
p u r chase at klipsch.com.
Accessories
A number of accessories are available for the GMX
D-5.1, including floor stands and wall-mounting
brackets for the satellites and grille and foot kits color-
c o o r dinated with the leading game consoles. For
m o r e information, visit your dealer or klipsch.com.
