Introduction
Thank you for purchasing Monitor Audio Gold Signature loudspeakers.
The new Gold signature range has been designed from scratch with
improvements in every area, whilst the ethos of the original Gold reference
series has been preserved. All parts are made from die-cast alloys and in the case of the
driver chassis and chassis clamp system, a combination of cast aluminium and Zinc are
used alternately to provide a structure that has different resonance properties, thus
providing a high degree of resonance cancellation and damping. The cabinet is
more rigid with ‘old style’ tongue and groove construction and better internal
bracing. The plinth is also now made from a rigid cast alloy with a discreet aerofoil
profile. New metal feet and spikes round off this highly accomplished package.
The new RST®2 cone profile has been refined to provide better control of break up.
A new C-CAM® gold dome tweeter has been developed to propel high frequency
performance to beyond 40KHz. Extensive development has also resulted in another
unique feature; the HiVe®2 port design. This new port technology uses a straight rifled
construction to aid air flow and reduce turbulence.
In with the GS LCR, you will find four self adhesive rubber pads that can be placed on
the bottom of the cabinet to protect it against scratches and also to prevent vibrations
moving it. The GS FX comes with a wall fixing kit including all of the parts to secure
them to a wall.

Please retain this manual for future reference. Safety Instructions
1. Read Instructions
Please read and follow all of the instructions in this manual before enjoying
your loudspeakers. Any instructions preceded by this warning triangle MUST
be followed. Failure to do so may cause personal injury or damage the
speakers.
2. Water & Moisture
The loudspeakers should not be used near water - for example, bathtub,
washbowl, kitchen sink, washing machine, in a wet basement or near a
swimming pool. Under no circumstance should plants or fish bowls be placed
on the products.
3. Heat
The speaker/s should not be placed near any heat source such as radiators,
open fires, stoves, direct sunlight and any other appliance that produces heat.
These speakers are designed for use within the home environment.
Exposure to extreme temperatures & humidity when placed on patios or open
conditions could adversely affect the wooden cabinet.
4. Cleaning
Great care and attention has gone into the materials chosen to
produce the Gold GS loudspeakers. It is our intention that they should
provide a lifetime of musical pleasure. A gentle wipe with a dry, clean
cloth is all that is required to remove any dust. Treat them as you would
a fine piece of furniture because that is how they have been designed.
Avoid touching the loudspeaker’s drive units whilst cleaning, as any damage
will impair their performance.
5. Re-cycling
When it is time to replace this product please help us protect the
environment by disposing of it in an appropriate and responsible manner.
Further details are available from www.monitoraudio.co.uk
6. Natural wood veneers
Monitor Audio takes great pride in providing a high quality product.
We use only hand selected natural wood veneers, which are
carefully matched and hand finished to the highest standard possible.
The unique nature of each veneer may result in natural colour variation
and grain from samples you may have seen in photos or at the dealer’s
show room. This is what makes the product a special piece of furniture.
If your speaker is finished in a Cherry veneer please be aware that it will
naturally darken with age, more so than other types of wood veneer.

A centre speaker is often required to produce over 60% of the entire sound output
and, therefore, must be able to faithfully reproduce explosions and sound effects as
well as it does clear, tonally accurate dialogue. The outstanding dynamic reach and
generous power handling of the GS LCR means that it can cope with the most demanding
inputs and always have something in reserve. New design ideas have been employed to
optimise accuracy, control and dispersion over a wide listening area. And it has the
exact tonal signature and balance to integrate “invisibly” with any of the speakers in
the Gold Signature range.
The GS LCR has been designed to work just as well as a main left/ right speaker as it
is as a centre speaker. Because of this, if it is being used vertically, please ensure the
cabinet badge is always on the right. By doing this means that the low frequencies go
to the bottom bass unit and the mid frequencies go to the top bass unit.
To remove the grille, carefully prize it away from the cabinet using you fingers. The
main grille locates in the elongated holes around the outside of the driver chassis. To
replace it, line the peg fixings (in the grille) up with the elongated holes and gently
press into place.
For system set up please see positioning ideas on pages 7 and 8.

Your Gold GS FX
The new GSFX is a completely new design from Monitor Audio. A combined di-pole and
monopole speaker for use in high-end or professional cinema applications.
In monopole mode the front firing RST®2 bass/ mid-range and C-CAM® tweeter
provide an accurate full-bandwidth sound-field for use in multiples or as a rear effect.
In di-pole mode the side firing drivers (one set at each end), combined with the tailored
output from the front firing driver, to provide a diffused sound-field for use as a pure
effect speaker in a more advance installation. The di-pole drivers have also been design
to be a 2-way compliment incorporating a 4” C-CAM® bass driver and 25mm C-CAM®
gold dome tweeter. When in dipole mode the front tweeter is disconnected, and the
crossover frequency of the main driver lowered.
To remove the grille, carefully prize it away from the cabinet using you fingers. The
main grille locates in the elongated holes around the outside of the driver chassis. To
replace it, line the peg fixings (in the grille) up with the elongated holes and gently
press into place. The side grilles locate in recessed grommets in the cabinet itself.
These can be a very tight fixing.
For system set up please see positioning ideas on pages 7 and 8.

Setting up the GS FX (Optimum Performance)
12 volt Trigger.
When DVD soundtracks are made, they are done so with the original cinema
reproduction in mind. In movie theatres, there are a greater number of speakers than
discreet channels. Because of this, you get an effect that encompasses the viewer a lot
more, and the imaging from front to back, and left to right is a lot more seamless. The
closest to a cinema the majority of people can practically have is a 7.1 system. This is
where the 12 volt trigger comes into its own.
When you have a 7.1 system set up, and the DVD that is being played has been set up to
recognise 7.1, the AV amplifier will see this and switch the speaker to dipole mode via
the 12 volt trigger. If the DVD is only 5.1, the AV amplifier will also see this and not send
the signal to the GSFX, therefore enabling it as a full range speaker.
The trigger inputs can be seen in the below image, above the speaker terminals. This is
connected to your AV amplifier/ receiver, and determines the mode of the GSFX (mono/
dipole). For the trigger to work, the monopole/ dipole switch on the front needs to be
set to ‘monopole’. Please refer to your AV amplifier manual for further instruction.

Front Panel Switches
Monopole/ Dipole Switch.
This switch determines the actual
mode of the GS FX. When used
in a 5.1 system as rear speak-
ers, set the switch to monopole.
If they are used in a 7.1 system
as side speakers set the switch
to dipole. If you are using 4 GS
FX’s (side and rear) set them all
to dipole mode. Please see the
illustrations on pages 7 & 8 to
determine what position the
‘Location Switch’ needs to go
in 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.
Location Switch.
This switch is used to determine
the location of your GSFX’s.
Please refer to the illustrations on
pages 7 & 8 for correct
positioning. This will only make a
difference when the Monopole/
Dipole switch is set to ‘dipole’
mode.
Tweeter Attenuation Switch.
This switch adjusts the level of
the main high frequency tweeter
unit. In the middle position there
is no attenuation. Place it in the ‘-‘
position and the high frequencies
will be attenuated by 3dB. Place
it in the ‘+’ position and the high
frequencies will be boosted by 3dB.
