The Front LED Does Not Light Up

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

       way.

  ➞

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

      voltage.

Verify 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.

Verify 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 (+45 2343 8007
or [email protected]).

The Front LED Lights Up but There is No Sound

  ➞

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.

Troubleshooting

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

The Sound Quality Changes

  ➞

Perform 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 Studioquake’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.
