Thank you for purchasing the MPower series of powered studio monitors:

MPower 6 and/or MPower 8.

When it comes to studio monitors, one would want sound clarity, accurate

audio reproduction, transparent performance with low distortion and

exceptional imaging. Each component of the MPower studio monitors was

meticulously chosen to deliver those desired characteristics.

The built-in amplifier of the MPower monitor accepts unbalanced (RCA)

and balanced (1/4” TRS and XLR) inputs. It also features High Frequency

adjustment control for listening personalization.

The woofer installed in the MPower monitor uses Aramid glass fiber cone

which is stiff and has low mass, allowing the woofer to have low harmonic

distortion. The ultra efficient ribbon tweeter has flatter impedance and

better response. The combination of these two components ensure

dynamic, melodious balance, transparency and neutral audio reproduction.

7. Volume Control

This volume knob controls the MPower monitor’s input

sensitivity. Typically, you would want to set this knob to the

maximum setting (+6dB), adjust the source’s output level

and then use this volume knob to match the left and right

MPower monitors.

8. HF Adjustment

This high frequency adjustment is factory set at 0dB.

Simply adjust accordingly to your listening preference.

Simply slide the selector to the

required power input setting and replace the fuse to the

proper rating prior to connecting the monitors to the

power source.

USE OF IMPROPER VOLTAGE MAY RESULT IN

HAZARDOUS CONDITIONS AND/OR DAMAGE TO THE

MONITOR COMPONENTS THAT ARE NOT COVERED

BY THE FACTORY WARRANTY.

FOR YOUR SAFETY, PLEASE MAKE SURE THAT THE

MONITOR IS NOT CONNECTED TO ANY POWER

SOURCE PRIOR TO ACCESSING THE AC SELECTOR

AND FUSE COMPARTMENT.

This AC line connector is fused to protect the amplifier from

unwanted power surges. Be sure to use the proper fuse

rating when replacing the existing fuse:

M6: ø5 x 20mm 2A/250V UL/VDE slow blow tube fuse

M8: ø5 x 20mm 3.15A/250V UL/VDE slow blow tube fuse

To access the fuse compartment, simply

unplug the power cable from the monitor,

place a flat-head screw driver in the small

notch and pry it open as illustrated.

Placing Your MPower Monitors

Proper placement of your MPower studio monitors is crucial to their

performance.

Studio/Stereo Application

We suggest placing the monitors within the front 1/3 of the room, about 3 to

5 feet away from each other and directed at a 60 degree angle towards the

listening position.

Surround Sound Application

Begin by placing the center channel monitor right in front of your listening

position. Then place the front left and right monitors at equal distance and

about 25 - 30 degree angle from the center. The three front monitors (left,

center and right) should form a slight arc as shown below. Continue by

placing the rear monitors at equal distance from the listening position and

angled about 90 - 110 degrees from center as illustrated below.

To reduce distortion by reflection and diffraction, we suggest placing the

MPower monitors at least 3 feet away, at ear level of the listening position.

To achieve the optimized performance, you may angle the monitors so they

are aimed towards your ears when in listening position.

Avoid placing any large objects near the monitors and listening position.

Troubleshooting

The Front LED Does Not Light Up

The Front LED Lights Up but There is No Sound

Inspect the power cable. Never use one that has been altered in any

way.

èVerify the power AC outlet is active and supplying the appropriate AC

voltage.

èVerify the monitor’s AC selector is at the proper setting with the correct

fuse installed (refer to page 7 for fuse rating and how to access the

fuse compartment). Make sure that the fuse is not blown.

èVerify that the power cord is securely plugged into the unit and into the

power AC outlet.

Make sure the monitor’s POWER switch is ON.

If the fuse(s) blow once the monitor is switched on, please contact

Earthquake Sound’s Support/Technical Team for service (1-800-576-7944

or [email protected]).

Perform the troubleshooting steps above prior to proceeding with the

next steps.

Verify that all devices plugged into the same AC outlet are still working.

Make sure that the signal source (e.g. mixing console, CD player work

station, etc.) is at a level that can properly send a signal to the

monitor(s).

Make sure that the VOLUME knob (system gain potentiometer) is

turned fully clockwise to +6dB.

Make sure that the audio source cable is firmly plugged into both the

source output and the monitor input.

If you are using two monitors and this problem only occurs on one of

the units, exchange the audio input cable from the non-working unit to

the working one to determine where the problem lies (the monitor, the

cable or elsewhere).

If the problem still persists at this point, please contact Earthquake Sound

for service.

The Monitor Suddenly Stops Working

Turn the monitor off.

Perform the troubleshooting steps above prior to proceeding with the

next steps.

Carefully, check to see if the amplifier’s back plate is hot. It is possible

that the protection circuitry of the amplifier kicked in and shut the

amplifier down because it had been running at highest power output

for an extended period of time. Turn the monitor power off and keep it

off for at least 30 minutes to allow the amplifier to cool down before

turning it back on.

Increase the volume to check for normal operation.

If the monitor is still unresponsive, please contact Earthquake Sound for

service.

The Sound Quality Changes

èPerform

the previous troubleshooting steps before proceeding with

the next steps.

Disconnect the signal cable at the monitor’s input. With the monitor

powered on, place your ear close to each driver (tweeter/woofer) and

listen for any noise (i.e. a slight hiss or hum). If no noise of any kind

was heard, it is possible that one or more of the drivers (woofer,

tweeter or both) is faulty. It is also possible that the problem lies

elsewhere in the electronics.

Reconnect the signal cable to the monitor’s input and play some non-

distorted source material at a low volume. Carefully cover the tweeter

to block the sound. If the woofer sounds distorted or has no sound at

all, then the woofer may have gotten internally disconnected or may

need to be replaced.

Play the same non-distorted source material but cover the woofer

instead so the tweeter is mostly heard. If the sound from the tweeter is

not of clear tonal quality or if there is no sound at all, then the tweeter

may have gotten internally disconnected or may need to be replaced.

Please contact our Support/Technical Team once you isolate the issue to

get the best solution to fix your monitor(s).

The Monitor Produces Hisses, Hums or Other Loud Noises

Make sure the power cord is firmly plugged into the monitor.

Check the connection between the signal source and the monitor.

Note that the MPower’s XLR and TRS connectors are completely

balanced. If you are connecting an unbalanced signal to the monitor,

make sure to use Pin 2 for signal and tie Pin 1 and 3 together at the

source end.

Make sure that the AC mains is matched to the operating voltage

requirements.

Make sure that all audio equipment in your system uses the same

ground point. Avoid connecting dimmers, neon signs, TV screens and

computer monitors to the same AC output of your audio equipment.
