Unpacking:
Please save the ight cases for future shipping needs. You can use the included custom
cover to cover the ampliers when not in use. Do not cover the ampliers while in
standby or during operation.
e MTRX2 comes packed in its own individual custom made
heavy duty ATA ight case. Included are the premium Kimber
power cables, CD manual plus included documentation.
e ight case also has removable heavy duty wheels with
brakes, making it easy to move the ampliers close to the
appropriate install position.
To unpack the amplier two people are required to unlock
and carefully li the top cover of the ight case over the
amplier. Remove the custom amplier cloth cover before
liing the amplier out of the ight case.
Do not attempt to li or move the MTRX2 without adequate assistance. At least two people
are required to li or move the MTRX2 amplier. A third person is highly recommended
when removing the amplier o the ight case base/platform. While liing the amplier up
o the base/platform, the third person should stop the base/platform from moving. Once
the amplier is lied up o the base/platform the third person can easily slide the
base/platform away and the amplier can then be lowered to the ground.

Location & Precautions:
• Install MTRX2 amplier on a solid level surface.
• Install the MTRX2 in a dry and well ventilated location out of direct sunlight.
• Allow at least 60cm or 2 feet of clearance behind the amplier for power cords and cable
clearance.
• Allow at least 30cm or 1 foot of clearance above and around the amplier for proper heat
dissipation.
• Do not cover amplier with custom cover during standby or operation.
• Do not cover or obstruct ventilation holes or heatsinks.
• Do not place the MTRX2 close to low level components. e MTRX2 is a power amplier
capable of producing large output currents and hence large magnetic elds which can
interfere and induce noise in sensitive components.
• Do not install or expose the MTRX2 to sources of heat or open ame, steam, water,
dampness, excessive humidity, smoke or dust.
e MTRX2 amplier must be connected to a mains socket outlet with a protective earthing
connection (grounding pin). Do not install a “ground lier” or “cheater” adaptors.

MTRX2 Power Requirements:
e MTRX2 is pre-congured at the factory for 100, 110-120 or 230-240VAC operation at
50 or 60Hz depending on customer requirements. Please make sure to check that the Voltage
Indicator label on the back of the MTRX2, under the power inlet, matches the correct
voltage before installation.
e MTRX2 is capable of incredible performance due to its ability to
deliver huge amounts of power instantaneously to drive the most
complex and dicult loads. Depending on listening habits and
speakers used the limiting factor may be your electrical service.
For optimum performance and to take full advantage of the MTRX2’s
remarkable power handling capabilities we strongly recommend that
each MTRX2 amplier be congured and installed on its own
dedicated AC circuit. For maximum power each MTRX2 should be
congured and installed on its own dedicated 230-240VAC circuit.
Building regulations and electrical codes dier from location to
location and country to country. Please consult a local licensed
electrician with regards to installation of the dedicated AC circuits
for the MTRX2 ampliers.

MTRX2 Power Modes and Precautions:
O: AC power is disconnected either using the Main Power Breaker Switch in the
back of the MTRX2 or by disconnecting/removing the main power cable
from the power inlet. Please see diagram on the right.
Standby: Power cable connected and Main Power Breaker Switch turned to the ON
position. Safety, control and operational systems are enabled. MTRX2 indicator
lights will glow RED. In Standby mode the MTRX2 consumes minimal power.
On: Once in Standby mode press the front panel Standby button to fully power the
MTRX2 amplier. e MTRX2 amplier will take between 5-10 seconds to go
through a complete systems and safety check before enabling full power. Once
at full power the MTRX2 indicator lights will glow BLUE.
Ind. O: MTRX2 will be ON but indicators will be o. Press and hold the front panel
button for 2 seconds while in Standby mode. e MTRX2 will fully turn ON,
indicators will glow BLUE for a few seconds before dimming and turning o.
To re-enable indicators, press the front panel button for Standby mode then
back ON again.
Recommended Turn ON an Turn OFF Sequence
Turn ON Sequence:
1. Check that Main Power Breaker Switch is OFF (down position)
2. Connect speakers/speaker cables to MTRX2 amplier
3. Connect power from wall plug to power inlet of the MTRX2 amplier

Standby Mode. Indicator lights will go from BLUE to RED
2. Once in Standby Mode you can remove the audio source cables (XLR/RCA)
3. Turn OFF (down position) the Main Power Breaker Switch to completely turn o the
MTRX2 amplier and to remove speakers cables or disconnect power cables.
MTRX2 Power Modes and Precautions:
MTRX2 amplier should always be placed in Standby Mode before turning the Main Power
Breaker Switch OFF (down position). Turn the Main Power Breaker Switch OFF (down
position) before removing speaker cables, power cables or when moving or relocating the
MTRX2 amplier.
We recommend unplugging the MTRX2 (30A 250V 3-pin, IP44, IEC60309 type) from the
main AC circuit during lightning storms or when unused for extended periods of time to
prevent damage from power surges.

Each MTRX2 amplier has a USB connection and an RS232 connection for system updates
and for diagnostics and real-time monitoring. ese ports allow for remote control,
monitoring and real-time diagnostics of the MTRX2 amplier via the onboard computer and
internal sensors.
MTRX2 Diagnostic and Safety Systems:
e MTRX2 amplier is equipped with a full and detailed set of sophisticated and
comprehensive diagnostic and monitoring systems. On top of providing critical safety, these
systems also perform real-time monitoring of the amplier. is allows the MTRX2 to both
perform at its maximum performance and to immediately protect not only itself but
speakers and source components when it detects issues and faults.
is includes a comprehensive short circuit system protection and fast oset detection.
All of which are implemented outside of the MTRX2’s critical audio paths. us ensuring
that while the MTRX2 is completely protected, its audio paths are never compromised.
