Setting up the GX-FX
The Gold GX-FX’s are independent speakers that can be tailored to be either left or right
handed at the flick of a switch. Likewise, they can be operated in either di-pole or mono-
pole modes. The default factory setting is mono-pole.
In mono-pole mode, only the main driver and tweeter will be active. In di-pole mode, the
main tweeter is disengaged and the side drivers and tweeters are active. The front firing
tweeters are out of phase with the other tweeter and mid/bass unit. It is recommended to
implement this configuration when using two pairs GX-FX as part of a 7.1 channel system,
with the GX-FX’s taking up positions on side and rear walls. Please note, it is essential they
are positioned correctly when used in a 7.1 channel system. Please refer to the switch
positioning images on pages 8 and 9.
NOTE: Before adjusting any switches, please ensure that the speaker wires
are disconnected from the loudspeakers or amplifier. This will help to
protect the amplifier.
Tweeter Attenuation Switch.
This switch adjusts the level of
the main high frequency tweeter unit. In the middle position, there
is no attenuation. Placed in the ‘-’ position, the high frequencies
will be attenuated by 3dB. Placed in the ‘+’ position, the high
frequencies will be boosted by 3dB.
Location Switch.
This switch is used when determining the
location of the GX-FX’s. Please refer to the illustrations on pages
10 & 11 for correct positioning. This will only make a difference
when in ‘di-pole’ mode.
Mono-pole/ Di-pole Switch.
This switch determines the
actual mode of the GX-FX. When part of 5.1 systems as a rear
speaker, set the switch to monopole. If part of a 7.1 system as
side speakers, set the switch to di-pole. If using 4 GX-FX’s (side
and rear) set them all to di-pole mode. Please see the illustrations
on pages 8 & 9 to determine the setting of the ‘Location Switch’
depending on system set up.
If you are using the 12v trigger, set the switch to monopole mode.
The trigger will switch a relay to enable the di-pole mode.
12 volt Trigger.
(Not shown) This feature is present on some AV
amplifiers. It is possible to customise the 12v trigger to switch
the speakers to di-pole for certain sources. For example, multi-
channel music should be listened to in mono-pole mode, however,
movies should be listened to in di-pole mode. This feature automates the switching
between the two modes. Please refer to your AV amplifier manual for further instruction.
2 Channel Positioning
When arranging a 2 channel system, the listening position and the loudspeakers should
form an equilateral triangle. The speakers should be positioned approximately 6 - 10 feet
(1.8 - 3m) apart. The ideal distance from the rear wall varies depending on the speaker (see
list below), however, they need to be a minimum of 3 feet (91cm) from the side walls.
• GX50 and GX100 8 - 18 inches (20 - 45cm)
• GX200 18 - 24 inches (45 - 60cm)
• GX300 upto 36 inches (91cm)
Experimentation is strongly advised when initially setting up the speakers, as environment
and personal preference differ with every installation. If there is insufficient bass for example,
try moving your speakers closer to a wall. The opposite approach is recommended if there
is excess bass. Also see the information on page 7 refering to Port Bungs. If stereo imaging
is being lost, try ‘toeing’ them in slightly. The sound should appear to originate from the
centre point between the speakers, not the actual speakers themselves.
Fixing the GX-FX to a wall
CAUTION:
Always determine where the GX-FX will be fixed and the structure of the wall.
For safety reasons, if unsure of your ability to provide a secure and safe fixing, do not
attempt to fix these speakers to a wall. Instead, please obtain the services of a competent
and qualified trades person.
CAUTION:
Ensure that water pipes or electricity cables do not run behind where the wall
plate is going to be secured. Work from secure steps and avoid trailing wires.
NOTE:
We do not supply wall fixing screws and plugs with the GX-FX. Please only use
suitable fixings for the type of wall construction the GX-FX’s will be fixed to.
To fix the GX-FX’s to a wall, we would recommend using the wall fixing template provided
within the packaging carton. Fix the wall plate to the wall, connect the speaker cables, and
12v trigger cables (if being used) and hang the cabinet on the wall plate.
