EXPOSURE LEVELS AND USE OF
HEARING PROTECTION.
OPERATING ENVIRONMENT:
The amplifier is designed for use in environments which
protect it from rain, unusually high air humidity and
temperature.
Place on a surface where it cannot be easily dislodged,
potentially causing damage to the unit or injury to a person.
Ensure that the location will not expose the amplifier to
spillage of liquids/drinks, sprays/vapours or high humidity.
Ensure the amplifier is installed in a place which is not
subject to abnormally high temperatures and maintain
sufficient ventilation to prevent overheating.
For temporary use outside, apply similar caution however,
careful to ensure placement accounts for changing weather
conditions and that extreme wind/rain/heat will not find its
way to the equipment.
When taking any equipment from a cold environment
(unheated storage, vehicles, etc), into a warm one, allow the
equipment time to become acclimatised to the ambient
temperature, as condensation is likely to form in the
amplifier, potentially causing it to malfunction if put into
service too soon.
Note: This equipment has been tested and found to comply
with the limits for a Class B digital device, pursuant to part
15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a
residential installation. This equipment generates, uses and
can radiate radio frequency energy and, if not installed and
used in accordance with the instructions, may cause harmful
interference to radio communications. However, there is no
guarantee that interference will not occur in a particular
installation. If this equipment does cause harmful
interference to radio or television reception, which can be
determined by turning the equipment off and on, the user is
encouraged to try to correct the interference by one or more
of the following measures:
— Reorient or relocate the receiving antenna.
— Increase the separation between the equipment and
receiver.
— Connect the equipment into an outlet on a circuit different
from that to which the receiver is connected.
— Consult the dealer or an experienced radio/TV technician
for help.

(2) Indicator Section, Status:
a. Power Indicator
This indicator shows when the amplifier is on and is receiving power.
b. Parallel Mono Mode Indicator
This indicator shows if (parallel) MONO mode is selected on the rear panel.
For channel pair A and B only Input A will be used to drive both channels. Full
independent level control of the amplifier output stages is still possible via the Gain
controls.
c. Bridged Mono Mode Indicator
This indicator shows if Bridged mode is selected on the rear panel. It is most
important that this indicator is not illuminated unless bridged mode is required. This
is because when bridged mode is selected, Channel A will be out of phase with
Channel B. This will result in poor bass response and an unsatisfactory sound if left
and right outputs are used. In this mode Channel A controls the output level.
d. Protect Indicator
This indicator lights briefly during the power up cycle and also lights should a
fault occur. Illumination of the protect indicator, shows that the output of the
amplifier has been disconnected by means of an internal relay to protect connected
speaker systems from being damaged by the fault.

The level of each Channel is individually adjusted by these controls.
Rotating these controls fully clockwise, results in no attenuation to the incoming audio
signals.
(4) Indicator Section, Signal levels:
These show the (Peak) output level of the amplifier for each channel, in both
Stereo and Mono modes. These will start to illuminate when a signal is present at the
speaker sockets when driven above a threshold of approximately -9db. Note that for
levels below this amount the led may not illuminate. The signal level lights are useful in
indicating how much power is being sent to the speaker connected. The -9db threshold
relates to approximately 12.5% of the amps available power at the load it is connected
to. The table below gives the ratings at -9db for typical impedances connected.
Signal lights starting to blink at -9db
For every increase of 3db that occurs, a doubling of the power is needed, so to that
effect, when the signal lights start to stay permanently on at -6db the power the amp
produces is doubled. Most stage volumes will occur somewhere between the two
Signal lights starting to stay on at -6db
but if you’re happy with the volume levels and the signal lights are not lighting up,
that’s fine!

(5) Cooling Fan Outlets
Hot air exits here. Make sure all rear (and front) ventilation paths are
free from obstruction and air flows freely, otherwise the amplifier will
trip into thermal protect mode prematurely and in some extreme
circumstances damage may occur.
(6) Output Connectors
The Output sockets are Neutrik® Speakon / 1/4” combi connectors.
They accept both Neutrik® NL2FC & 1/4” jack plugs (NL4FC
accepted, however only terminal pair 1 carry signals). Avoid inferior
alternatives, as they may present numerous hazards due to less than
ideal construction.
9
When inserting speakon plugs turn clockwise until you hear it
click; This ensures correct connection has been made. To remove, pull
back the levered tab and turn anti-clockwise.
Ready-made, sensibly priced, quality interconnection leads
suitable for use with the amplifier should be easy to source. However,
with sufficient skill, it is possible to make/modify leads for the task.
•Only the first two pins (+1 and -1) are used in this amplifier.
•When utilising the 1/4” output option the centre pin (Tip) is
connected to +1 & the outer sheath (Sleeve) is connected to
-1.
•For STEREO/MONO operation, unmodified “off the shelf”
cables will usually work fine.
•For BRIDGED MONO mode, Output is exclusively available
from OUTPUT X, do not use at any other time.
5
Page 7
CAUTION: Whilst we recommend that Neutrik speakon connections
are always used for the safest way of connecting to the amplifier, the
option is also provided to use 1/4” jack connections with these
outputs. Take extra care when connecting leads to ensure that these
are not accidentally connected to the inputs and outputs of other
equipment not designed specifically to do so, otherwise damage to
equipment is likely to occur.
Take extra care with 1/4” jack speaker connections, the exposed plug end
can present an electric shock hazard, also never allow the outputs to be
shorted, equipment damage may occur. Finally, never use standard 1/4”
instrument leads for connection between amplifier and loudspeaker, choose a
quality speaker lead for this specific task for safe operation. and optimal
performance.
(7) Input Signal Sockets.
These are Neutrik® combined female XLR and 1/4" jack sockets.
For cable runs of under 12”, (ie. within a rack system) standard good quality
instrument leads should provide a similar level of RF shielding to XLR cables.
For longer cables runs, balanced cables (XLRs) are recommended.
(8) Output Mode Selector.
STEREO, MONO or BRIDGED (mono) Output can be selected using this
switch.
Take care to ensure the correct mode for your application is selected.
•In Stereo mode, channels A and B operate independently, when fed
with separate input signals. (Think of this as two separate mono amps
fed by their own input.)
•In Parallel (Mono) mode, Input A is connected to feed both amplifier
channel A and B. Input B is not used. Full independent level control
over each amplifier output channel remains possible. (This is useful if
you want to send the same mono signal to two separate cabs).
•In Bridged (Mono) mode, the input from channel A is fed out of phase
to channel B and combined to give a higher power mono output.
Note: Bridged Output X is used exclusively for this mode, do not
use at any other time. Using output channel A or B whilst
Bridged mode is selected will give a thin, out of phase sound,
lacking bass through those outputs.

Page 8
(9) Power Connection
Mains power is supplied to the amplifier by a standard 10 Amp IEC
mains socket.
An appropriate mains lead is supplied with the amplifier.
Note: The amplifier requires a stable power supply to function
as intended. Ensure that the power source (mains power
supply, generator, etc.) is suitable for this application and
adequate power is available. Poorly selected power sources
result in sub-optimal performance, increased likelihood of
tripping breakers, blowing fuses and in extreme situations
damage to equipment may occur.
BEFORE YOU START:
If you intend to rack mount your GT series amplifier you may want to
consider removing the rubber feet from the amplifier to allow maximum
room for other units that may share the rack space. This is a simple
process. Using a small flat bladed screwdriver gently prise the shiny plastic
insert up from the chassis which will enable the feet to be removed. Store
somewhere safe!!
1234
To replace the feet simply pull the plastic insert so the mechanism is closed,
line up the foot with the chassis hole and push into place.

GETTING STARTED, POWERING UP & CONNECTIONS:
Your GT Series amplifier comes equipped with a power lead specific for the
requirements of your country. Use only the correct lead with the correct rated
fuse for your country’s power requirements. Use of an incorrect lead or fuse
rating could lead to damage of your amplifier.
NOTE: Unlike a Valve powered amplifier, it is not
necessary to connect a speaker (or load) to the amp
whilst it is powered on. Powering on or operation of the
amp without a speaker or load attached will NOT damage
the amplifier.
1.Connect the supplied mains power lead to the IEC inlet on the rear of the
amp.
2. Connect the signal source (this can be your pre-amp, modelling device or
main outs from your effects unit) to the inputs on the rear of the amp. If you
are running in mono from your source, then only use one channel of the amp
and keep the amp in stereo mode. Note: If you are running the Matrix amp
as part of a wet/dry or wet/dry/wet system then make sure the connections
between your ampfier or source are in place to the effects system you intend
to use before feeding the signal to the Matrix amp.
3. Connect the GT amplifier to a speaker or cabinet with a good quality
speaker cable. Never use a screened (shielded) guitar cable for this as you
may damage the cable and the amplifier. The GT-series amps will accept
various standard impedance cabinets and even non standard but bear in
mind that the total load must NOT exceed 4 ohms per channel (or 8 ohms
in bridged mode).
4. Making sure that the amp is turned off at this point, power up your signal
source (this prevents any unwated signal noise transmitted to your
speaker(s). Now with the volumes on the amp all the way down, power on
the amplifier via the power switch located on the front. You may hear a
slight “thump” as the unit is powered on. This is perfectly normal.
5. Adjust the controls of the input source to a required level (ideally 0db or
.775v) and steadily increase the GTs volume until a sufficient level is
achieved.
6. Adjust the levels of the relevant volume controls on the Matrix amp until
desired volume is achieved.
8
Page 10
NOTE: The Matrix’s volume controls are basically
attenuators. That means that to achieve full power at
their specified load they requires a signal of .775v
(0db) and the volume knobs up full. If you put a higher
level signal into the amp, it will achieve it's full power
rating earlier than at full volume position and inversely,
if you put a lower level signal in, say -6db, the amps
full volume will always be -6db of full power rating.
If your volume is lower than expected even with the Matrix amp on full
then look to increse the signal level going into the amp. This could be the
individual patch volume or the master volume of the unit or indeed the
send level of a preamp. Be aware of the noise floor of a unit as well.
Turning something up full will usually turn up the amount of noise the unit
generates. The Matrix units are obviously designed to be turned up full
and have a low level of noise/distortion but you may experience issues if
you turn up the signal being fed into the Matrix too much and have the
volume of the amp set too low.
Important Notice regarding connection to multiple
input and switchable input cabinets.
Care must be taken when connecting the amp to any
cabinet that has more than one jack plug or socket or
features switchable stereo/mono operating modes.
Certain cabinets are known to have more than one
socket but are not stereo capable cabs.
Orange® 2x12 and 4x12 cabs for instance have two unlabeled parallel
inputs. Connecting the amplifier to both inputs effectively shorts the
amplifiers outputs and will cause damage to the amplifier. This will not
be covered under warranty.
Similarly, cabinets which feature stereo/mono switchable inputs
(Marshall® style) must always be switched to stereo operation when
both channels of the amplifier are connected to it. Switching to mono
mode will turn the input into a parallel output and again effectively link
and short the amps channel outputs together. If you are unsure of your
cabinets’ specifications, please refer to the manufacturer’s instructions
or consult a qualified technician for guidance. Care must also be taken
with Mesa® style cabinets to use the applicable socket for stereo or
mono and manually switch to the correct one(s).
If in doubt consult your cabinets manual or relevant support page.

NOTE: The above system can also be adapted to run the Matrix as a “slave”
amp. Take care that the Matrix amp receives only a line level signal and not
a signal direct from the main amps speaker out otherwise damage will
occur. This can be from the amps line out or effects send or from a suitable
ISO/Load box with a line out facility. Care must also be taken to ensure the
main amp still has a “load” attached to it either in the form of a cabinet or
suitable load box.

traditional guitar cabinets and
FRFR systems for maximum
realism and tonal possibilities.
This cab could be 8 ohms
and the bottom cab could

INTERNATIONAL VOLTAGE SELECTION
Your Matrix amplifier should be set at the voltage for your specific country if
selected correctly at the time of ordering. It is possible however to select
alternative region voltages internally via an on-board switch.
This allows for selection of 230v or 110v modes respectively at +/- 15%.
This is approximately 200 to 265v or 95 to 125v.
If you are unsure about undertaking this procedure, please refer to qualified
service personnel.
To access the internal switch, firstly disconnect amplifier from all
equipment & mains supply as lethal voltages are present inside.
Next remove the screws on the lid shown below with a suitable
cross head screwdriver, the lid should now simply lift away without
obstruction, should any resistance be encountered, inspect for
further fasteners holding the lid down.
Within the region indicated below by the dotted area a
internal view similar to that shown below should be visible. With a
finger or ballpoint pen move the switch shown into its alternative
position for secondary voltage mode. Re-assemble amplifier
ensuring all fixings are tight before further use.
NOTE: Ensure correct voltage for region is always selected, otherwise
damage is likely to occur!

CABLE CHOICE & NEUTRIK® SPEAKON CONNECTORS
Whilst the Matrix GT series amps come with Neutrik® combi inputs and outputs for
maximum flexibility it is important to use good quality cables and connectors. We
recommend using Neutrik® branded connectors wherever possible. We’ve come
across certain low cost 1/4” jacks not connecting properly as well as XLRs not
“locking” which can cause loss or degradation of signal. Whilst many guitarists are
used to using traditional 1/4” jack to jack speaker cables we recommend trying out
Speakon connectors as they offer certain advantages over 1/4” jacks
•No possible confusion with low-current microphone or instrument cables.
•They lock into their sockets with a twisting motion, making them significantly
less prone to disconnection than push in jack plugs.
•They are shielded from human touch, preventing electrical shock from a high-
powered amplifier (especially important given the high wattage of our amps).
•The contacts do not short out during connection or disconnection. This can be a
benefit when working with sound equipment that is in operation.
•The chassis receptacles are airtight, so do not provide an air leak path from
speaker enclosures. (Important in high SPL FRFR cabinets)
•They are usually solderless connections making field maintenance and
construction much easier.
Whilst we appreciate that not everyone will convert their traditional cabs over to
Speakon connectors, you can still use Speakon to 1/4” cables to connect to the GT
series and at least get some benefit!
You can use either NL2FC or NL4FC Speakon connectors with the GT series but only
pins +1 and -1 are used if you use the 4 pole connector type!
If you decide to make your own speaker cables we recommend a twin core cable with
a copper core of at least 2.5mm2 / 12 awg. For cables longer than 6m/20ft a heavier
gauge cable may provide improved performance.
An approximate guide of cable sizing in relation to that of a pencil is shown
below, also note on the right the thin 'bell wire' / budget domestic speaker cable...
never use cable of this gauge to connect to power amplifiers, this can present a fire
risk and will result in poor performance.

TROUBLESHOOTING:
NOTE:
•Ensure the amplifier has no less than 4 Ohms worth of loading across
each channel for Stereo/Parallel modes.
•Ensure Bridge Mode (if used) is utilised via Output X and is loaded
with no less than 8 Ohms.
•Ensure wiring is safe and correct.
•When heavily driven, the amplifier itself may make a noticeable
hissing sound in relation to the supplied signal. This is a normal
phenomenon relating to the behaviour of certain components which
vibrate slightly under the high powers involved.
•The fans on the GT series may increase their speed when the
amplifier is under load to improve cooling efficiency.
.
(1) THE POWER LIGHT DOES NOT ILLUMINATE
•Check that the mains supply is turned on.
•Check that the mains switch is turned on.
•Check mains lead for damage & check fuse. Replace lead if damaged,
replace fuse if blown.
•Check internal fuse. Replace if blown.
(same type of fuse specified/installed must be used, do not change)
•If fuse re-blows refer to service personnel.
•Check voltage selector of amp is in correct position for required
voltage.
•If fuse has not blown and the voltage selector is in correct position but
the amplifier still malfunctions, refer to service personnel.
(2) OUTPUT VOLUME IS LOW
•Check the signal from the input source and check signal cables. The
amplifiers are designed to operate at an input voltage of 0.775V. If
the intended signal source is below this a lower output volume will
result. Raise the signal level from the source.
(3) NO OUTPUT VOLUME
•Check the amp is receiving a signal from it’s source.
•Check both input and output leads and replace and re-test. In the
case of outputs, if speakons are used make sure they are securely
attached or try a 1/4” cable.
•Check signal output lights are lighting up. These lights are directly
connected to the amplifiers output circuits so if they are lighting up,
the amplifier is outputting a signal and the problem lies elsewhere.
16
Page 18
(4) OUTPUT IS DISTORTED OR THIN SOUNDING
•The protection circuits (current clamps) are operating. Check all leads
for short-circuits. Try another set of leads and loudspeakers.
•Check the amp is not switched to bridged mode and non bridged
output is being used.
•Check leads for correct wiring.
(5) AMPLIFIER IS OVERHEATING (PROTECT LIGHT ON)
•Check that the fan is not obstructed with debris, and is operating and
rotating freely. If the amp is overheating the fans will run in high speed
mode which is audibly louder than normal mode. Switch off amp and
allow to cool. Power on and ensure protect light turns off.
(6) PROTECT LIGHT IS ON
The protect light will illuminate under certain conditions to prevent damage to
the amplifier or connected speakers.
•Check cabinet impedance is not less than 4 ohms per channel or less
then 8 ohms in bridged mode.
•If both channel outputs are connected, check cabinet is in correct
mode (see important notice on page 9) or is compatible.
•Check for short circuits in leads (try a different lead).
•Check for possible short circuit in speaker (try a different speaker).
•Make sure amp has sufficient air flow through fans and vents to avoid
the amp going into thermal protect.
•Power down, disconnect all leads except power and switch on. If
protect light extinguishes then problem was linked to one of the above
items.
•If the protection circuits have detected a DC signal or other damage the
amp will stay in protect mode.
If any of these, or other symptoms persist, please contact your dealer or
alternatively email us at [email protected] for help, advice
and service.

CARE & MAINTENANCE:
Your Matrix GT series amplifier should give you years of trouble free
service provided you take care of it. Any cleaning should be done with a
damp (not wet) lint free cloth and if needs be, the fans can be cleared
of any dust or debris using either a small brush or compressed air (the
kind suitable for cleaning computer devices). Do not use any abrasive
cleaning products as these may damage the powder coating or printing.
