MTRX REFERENCE AMPLIFIER

MTRS STEREO AMPLIFIER

EMM Labs is proud to present its latest innovation in audio

technology: the MTRS Stereo Amplier. e MTRS is a 400W Class

A/B solid-state amplier. e MTRS is able to drive the most severe

loads with no overall feedback, using Ed's completely re-designed high

current Meitner Power Driver. e MTRS can handle any speaker load

with ease, delivering high power, low distortion and wide bandwidth.

e MTRS also incorporates:

• A new proprietary power system

• Fully discrete circuits

• Fully balanced audio paths throughout

• Our custom ceramic PCB boards

• Real time protection to avoid speaker and amplier damage

e MTRS is the ultimate amplier for those who demand the best in

audio reproduction in a stereo package. Just like our reference MTRX

and MTRX2 ampliers, the MTRS Stereo Amplier is designed,

manufactured, and built in Canada with no compromise.

Installation

Unpacking:

Please save the ight cases for future shipping needs. You can use the included

cover to cover the ampliers when not in use. Do not cover the ampliers while in

standby or during operation.

e MTRS comes packed in its own individual custom made

heavy duty ATA ight case. Included is a premium

Kimber power cable, CD manual plus included documentation.

e ight case also has 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 amplier cloth cover before liing the

amplier out of the ight case.

Do not attempt to li or move the MTRS without adequate assistance. At least two people are

required to li the MTRS amplier. A third person is highly recommended when removing

the amplier o the ight case base/platform. 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.

Installation

Location & Precautions:

• Install the MTRS amplier on a solid level surface.

• Install the MTRS 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 during standby or operation.

• Do not cover or obstruct ventilation holes or heatsinks.

• Do not place MTRS close to low level components. e MTRS 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 MTRS to sources of heat or open ame, steam, water,

dampness, excessive humidity, smoke or dust.

e MTRS Stereo 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.

Operation

MTRS Power Requirements:

e MTRS is pre-congured at the factory for 100, 110-120 or 230-240VAC operation at 50

or 60Hz depending on customer/country requirements. Please make sure to check that the

Voltage Indicator label on the back of the MTRS, under the power inlet, matches the correct

voltage before installation.

e MTRS 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 MTRS remarkable power

handling capabilities we strongly recommend that that amplier be installed on its own

dedicated AC 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 MTRS Stereo Amplier.

Operation

MTRS Power Modes and Precautions:

O: AC power is disconnected either using the Main Power Breaker Switch in the

back of the MTRS 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. MTRS indicator

lights will glow RED.

On: Once in Standby mode press the front panel Standby button to fully power the

MTRS. e MTRS 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 MTRS indicator lights will glow BLUE.

Ind. O: MTRS with indicators o function. Press and hold the front panel button for 2

seconds while in Standby mode. e MTRS 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 and Turn OFF Sequence

Turn ON Sequence:

1. Check that Main Power Breaker Switch is OFF (down position)

2. Connect speakers/speaker cables to MTRS Stereo Amplier

3. Connect power from wall plug to power inlet of the MTRS amplier

4. Plug in audio input from source components

MTRS and to remove speakers cables or disconnect power cables.

MTRS Power Modes and Precautions:

MTRS Stereo Amplier should always be placed in Standby Mode before turning the Main

Power Breaker Switch OFF (down position). Always turn the Main Power Breaker Switch

OFF (down position) before removing speaker cables, power cables or when moving or

relocating the MTRS Stereo Amplier.

Operation

MTRS System Connections:

Each MTRS amplier has an RS232 connection for system updates and for diagnostics and

real-time monitoring. is port allows for remote control, monitoring and real-time

diagnostics of the MTRS amplier via the onboard computer and internal sensors.

MTRS Diagnostic and Safety Systems:

e MTRS amplier is equipped with a full and detailed set of sophisticated and

comprehensive diagnostic and monitoring system. On top of providing critical safety, this

system also performs real-time monitoring of the amplier. is allows the MTRS 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, comprehensive short circuit system protection and fast oset detection.

All of which are implemented outside of the MTRSs critical audio paths. us ensuring

that while the MTRS is completely protected, its audio paths are never compromised.

Care and Maintenance

Care and Maintenance (General)

e MTRS amplier requires just basic routine maintenance and care to ensure optimal

performance.

• Before performing any maintenance please ensure to turn the MTRS amplier OFF

and remove the power cable from the amplier.

• To remove dust from the exterior surface of the MTRS you can use a, low pressure

blower or brush it with a dry clean lint free or micro bre cloth.
