Signal Input Connections
The GMX control module has three audio inputs (see
Fig. 4A): Toslink optical digital, coaxial digital (orange
RCA jack), and stereo analog (red and white RCA
jacks). Use these inputs to connect audio sources, such
as a game console, DVD player, CDplayer, computer
sound card, or TVset. Whenever possible, use one of
the digital inputs, since this will allow Dolby Digital
playback. Fig. 4B illustrates asetup in which a game
console, DVD player, and TVset are connected to the
GMX D-5.1.
Important Note: Each input demands a particular
type of cable and a matching output on the source
component. The optical digital input requires a Toslink
fiber-optic cable. The coaxial digital input requires a
coaxial cable with RCA plugs on each end. To ensure
reliable operation,use a cable labeled for video or
digital audio connections. The stereo analoginput
requires a pair of ordinary shielded audio cables with
RCA plugs on each end. If you are connecting the
analog inputs to a devicethat has a minijack output,
use the supplied miniplug-to-RCA adaptor.
Speaker Setup
The subwoofer requires an AC power connection (do
not plug it in until setup is completed). All five satellite
speakers and the control module connect tothe sub-
woofer, which provides the power for all channels.
Set up the speakers as follows:
1) Place the satellite speakers around the area where
you will be sitting, more or less as illustrated in Fig. 1.
The center speaker should be directly above or below
your TV or monitor (the satellites are magnetically
shielded to prevent picture interference). Place the left
and right front speakers to either side and equidistant
from the screen. Place the surround (rear) speakers to
the left and right and slightly behind the seating area
and facing in toward it. If possible, all fivesatellites
should be about the same distance from the seating
area.
2) The subwoofer can go virtually anywhere that is
convenient, but we recommend placing it in the front
soundstage of your system and, if possible, against a
wall or in a corner.
3) Using the five supplied speaker cables, connect the
outputs on the back of the subwoofer to the matching
satellites, as shown in Fig. 2. The striped wire should
be connected tothe red speaker terminal.
4) Using the supplied multipin DIN cable, connect the
DIN output on the back of the system controlmodule
tothe DIN input on the back of the subwoofer (see
Fig. 2).
5) The satellite speakers attach to their pedestal
bases via a ball socket that allows a very wide
range of motion. Adjustments are simple as illustrat-
ed in Fig. 3.
ProMedia®GMX D-5.1
Welcome to the Klipsch ProMedia® GMX D-5.1
speaker system. The GMX D-5.1 is a high-perform-
ance powered speaker system consisting of five small,
identical satellites and a single subwoofer. It is operat-
ed from a compact, easy-to-use control module with
built-in Dolby Digital and Dolby Pro Logic II surround
decoders. Although designed primarily for use with
game consoles, suchas the Microsoft Xbox™and
Sony PlayStation®2, the GMX D-5.1 will also deliver
excellent sound as a multimedia speaker systemfor a
personal computer or even as the audioportion of a
small home theater.
IMPORTANT NOTE: Before You Begin
Do not plug in the GMX D-5.1 subwoofer’s power
cord until all other wiring is completed, and do not
disassemble the system before you have unplugged
the subwoofer’s power cord. Be especially careful not
to connect or disconnect any signal cables while
power is applied. Failure to observe this caution may
result in loud hums, buzzes, or pops that will at the
very least be annoying and that in the extreme may
damage your speakers.
Unpacking
Carefully remove the system components from the
carton:
• 1 Subwoofer
•5 Satellite speakers on pedestal bases
•1 Digital preamplifier and control module
•1 Multipin control cable with DC supply cord
•5 Speaker cables with RCA connector on one end
• 1 Stereo miniplug-to-RCA-sockets adaptor
• 1 AC power cord

Power Connections
The last setup steps are the power connections (see
Fig. 2). Plug the DC supply cord into the jack
labeled "Decoder Supply" on the subwoofer cabi-
net. Next, plug the other end into the jack labeled
"DC 7V IN" on the back of the GMX control mod-
ule. Plug the subwoofer’s power cord into a wall
outlet or AC power strip. Your GMX D-5.1 is now
ready to rumble.
The Control Module
Everything you needto run the GMX D-5.1 is on the
face of the control module. The function and opera-
tion of each control is listed below (see Fig. 4A):
1) Display. Indicates master volume setting and level
trim during setup.
2) Volume Pads. Press the (+) and (-) buttons to raise
or lower the volume. These buttons are also used to
adjust the levels of the speakers in the system relative
to one another (channel balance).
3) Power.Turns the system on and off. The red LED
indicates standby mode.
4) Input. Pressing this button selects one of the inputs.
Choosing an input will cause its indicator LED above
the button to light up.
5) Surround. Pressing this button selects one of the
available audio modes. Modes that can be used will
depend on the input and type of signal.
•Dolby Digital Signals: If you have selected one of
the digital inputs, it will automatically switch to the
appropriate Dolby Digital mode when a Dolby
Digital signal is present. The Dolby Digital indicator
LED (above the Surround button) will light. Dolby
Digital modes are available only when a Dolby
Digital signal is present at the selected digital input;
no surround changesmay be made toa discrete
Dolby Digital5.1 signal. The Surround button will be
active in Dolby Digital mode only when the signal is
two-channel stereo, as described immediately below.
• Stereo Signals: If you have selected the analog
input or a digital input receiving a PCM signal, such
as from a CD, you have a choice of four modes:
Stereo, 5-Channel Stereo, Dolby Pro Logic II Cinema
and Music. The Dolby Pro Logic II modescan also
be applied to a Stereo Dolby Digital signal. Switch
modes by pressing the Surround button until you
reach the one you want, as indicated by the LEDs
above the button. Stereo is indicated when no LEDs
are lit.
6) Test. This button turns the channel test signal on
and off. When on, the LED above the button will light
and you will hear noise for several seconds from
each satellite speaker in turn. The signal will rotate
from speaker to speaker in this fashion until you turn
it off. This signal has two uses:
• Making sure that all speakers are connected and
working.
• Helping you setchannel balance.Because the five
satellites in the GMX D-5.1 are identical, you will usu-
ally get correct channel balance automatically. To find
out, turn the test signal on and listen; it shouldbe
equally loud from each speaker. If not, you can use
the CTR and SURR buttons
(described below) together
with the volume pads to
adjust the level of the sur-
round speakers up or down
relative to the front left and
right.
The adjustment level trim is
from -9dB to +9dB, with
default settings of "0." Note:
Possible gain range settings
for each channel are -9dB to +9dB and will be
retained as the main volume approaches 60dB.
However, new settings made at high volumes will
only be allowed as the total reaches 60dB. In other
words, if the main volume reads 55dB, the boost will
be limited to +5dB, and if main volume is set to 60dB
(maximum), noboost is available.
7) Dyn. Comp. Toggles through the three modes of
the Dolby Digital dynamic compression function.
Dynamic compression reduces the level difference
between loud and softsounds. This can be useful
when you are having trouble hearing dialogue clear-
ly or when youwant to minimize disturbance ofoth-
ers by very loud sounds. Available modes are "Half,"
"Full," and "Off"; the selected mode will be indicated
by the LEDs above the button. "Off" selects no com-
pression, whereas"Full" selects maximum compres-
sion. This function is available only when the system is
processing a Dolby Digital input.
8) Sub. Allows adjustment of the subwoofer’s relative
level. To use, press the button until the indicator LED
lights. Use the volume pads to raise or lower the bass
level until youget the balance of lows to highs that
you want. The central display will show how much
boost or cut you haveapplied, in decibels (dB).
Pressing the button again until the LED goes out will
lock the setting and return thevolume pads to master
mode, controllingoverall level. To return to the origi-
nal setting, just turn the control on again and adjust
the level until the display shows "0." Note: This also
controls the "SWS Link" output level (see "SWS Link"
section).
9) Surr. Allows adjustment of the surround speakers’
level relative to that of the front left and right. To use,
press the button until the indicator LED lights. Use the
volume pads to raise orlower the surround level until
you get the balance that you want. The central dis-
play willshow "SR" or "SL" to indicate adjustmentof
the Surround Right or Surround Left output channel,
and thenswitch to indicate how much boost or cut
you have applied in decibels (dB). Pressing the button
once will allow youto adjust the surround right chan-
nel. Pressing the button a second time will allow you
to adjust the surround left channel. Pressing the button
again until the LED goes out will lock the setting and
return the volume pads to master mode, controlling
overall level. To return tothe originalsetting, just turn
the control on again and adjust the level until the dis-
play shows "0."
FIGURE 4B

10) Ctr. Allows adjustment of the center speaker’s
level relative to that of the front left and right. To use,
press the button until the indicator LED lights. Use the
volume pads to raise orlower the center chanel level
until you get the balance that you want. The central
display will showhow much boost or cut you have
applied, in decibels (dB). Pressing the button again
until the LED goes out will lock the setting and return
the volume pads tomaster mode, controlling overall
level. To return to the originalsetting, just turn the con-
trol on again and adjust the level until the display
shows "0."
11) Mute. Turns the sound on and off. When the sys-
tem is muted, the LED above the button will light.
12) Mode Indicator LEDs. At the top of the control
module, thereare three mode indicator LEDs. When
no LED is lit, stereo decoding is taking place. When
the incoming signal is decoded in 5-channel stereo
the "5 CH Stereo" LED will be lit. The "PLII" LED will
be lit when Pro Logic II movie mode decodingis tak-
ing place. When the "Dolby Digital"LED is lit, the
GMX is receiving and decoding a Dolby Digital bit-
stream. On Dolby Digital 2.0 signals, 5-channel
stereo and ProLogicdecoding 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-5.1offers five surround modes,
selected via the Surround button on the
GMX control module:
• Dolby Digital. This is a discrete-chan-
nel digital mode that allows 1- to 5.1-
channel reproduction. (The channels
are left, center, right, left surround,
right surround, and low-frequency
effects.) 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.
• Stereo. 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 Stereo. Available for all inputs receiving
analog or two-channel digital signals. It redistributes
a stereo signal across the five satellite speakers to give
very broad, even coverage. All five satellites and the
subwoofer are active.
• Dolby Pro Logic II. Available for all inputs receiv-
ing analog or two-channel digital signals. This mode
providesaccurate decoding of Dolby Surround-
encoded signals and natural, realistic five-channel
enhancement of stereo signals. All five satellites and
the subwoofer are active. Dolby Pro LogicII has two
sub-modes:
Cinema (Red LED) - Select for sourcesthat have
been encoded in Dolby Surround. This includes
many games, TV programs, and movies on video.
Music (Green LED) - This mode is especially appro-
priate for stereomusic, 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 theGMX
D-5.1 provides good bass output on its own, one or
more SWS subwoofers will add both depth and
power to your system’s bottom end. The Klipsch
ProMedia SWS subwoofer system is available for
purchase at klipsch.com.
Accessories
A number of accessories areavailable for the GMX
D-5.1, including floor stands and wall-mounting
bracketsfor the satellites and grille and foot kits color-
coordinated with the leading game consoles. For
more information, visit your dealer or klipsch.com.
