Symptom

Likely Cause

No sound

Speaker not connected to
active AC power

Verify that the speaker is connected and that the circuit is on.

No sound, speaker is
connected to working

AC power but won't

come on

Speaker power cable is faulty
or improperly connected.

Blown fuse

*Re-seat the power cable at both ends.
*Substitute a known-good power cable.

No sound

Speaker comes on

Signal source (mixer, Amp
instrument) is not sending

*Check that the signal LED indicators are lit.
*Verify that the tape or CD is playing.
*Use headphones to verify that the instrument is actually sending

an audio signal.

*Disconnect and re-seat signal cables.
*Replace the suspected cable with a known-good cable.

No sound with

microphone

connected to MIC /

LINE input

Microphone requires
phantom power

The EON does not supply phantom power. Switch to a dynamic
microphone, use a battery powered microphone (if possible),
use an external phantom power supply for condenser type
microphones.

Excessive input signal,
trying to exceed the
capabilities of the speakers

*Reduce the output level of the source.
*Turn down the level controls on the speaker.
*Use additional EON speakers.

Lots of hiss in sound.

Mixer controls are at

very low settings

Improper gain structure

Hum or Buzz

Improper A/C gr

ounding,

ground

loops

Excessively long
unbalanced cable run

Improper system gain
structure

*Use the balanced outputs (if available) of your mixer or source

equipments to drive your EON speakers.

*Use the "DI" (direct injection) box to convert unbalanced

equipment output to a balanced output.

Signal

distorted and
very loud, LIMIT light
is lit most of the time

Reduce the INPUT level controls and increase the output level
of your source devices.

Faulty cables & connections

*Make sure that the MIC/LINE switch is in the LINE

(disengaged) position.

*Reduce the level settings on the speaker. Review the manual

for your mixer and adjust the controls as needed.

*Input sensitivity (gain).
*Channel faders.
*Master faders.

*"Lift" audio ground using XLR/F to XLR/M adaptor on one end.
*Re-route audio cables away from AC power and lighting cables.

What to do

*Check fuse and replace with the same type and specification.

SAFETY RELATED SYMBOLS

CAUTION

RISK OF ELECTRIC SHOCK

DO NOT OPEN

The symbol is used to indicate that
some hazardous live terminals are
involved within this apparatus, even
under the normal operating conditions.

The symbol is used in the service
documentation to indicate that
specific components shall only be

replaced by the component specified in
the documentation, for safety reasons.

Protective grounding terminal.

Alternating current/voltage.

CAUTION: Describes precautions that
should be observed to prevent danger of the
apparatus.

WARNING

Power Supply

Ensure the source voltage matches the
voltage of the power supply before turning the
apparatus on.

:

Hazardous live terminal.

ON: Denotes that the apparatus turns on.

OFF: Denotes that the apparatus turns off,
because of using the single pole switch, be
sure to unplug the AC power to prevent
any electric shock before you proceed
with your service.

WARNING: Describes precautions that
should be observed to prevent the danger of
injury or death to the user.

This product should not be placed
in municipal waste and should be

tr

eated as Waste Electrical &

Electronic Equipment (WEEE).

Unplug this apparatus during
lightning storms or when unused for long
periods of time.

External Connection

The external wiring connected to the
output hazardous live terminals requires
installation by an instructed person, or the use
of ready-made leads or cords.

Do not Remove any Cover

There are some areas with high voltages
inside, so to reduce the risk of electric
shock, do not remove any cover if the power
supply is connected.
The cover should be removed by qualified
personnel only.
There are no user serviceable parts inside.

Fuse

To prevent a fire, be sure to use fuses
with a specified standard (current, voltage,
type). Do not use a different fuse or short
circuit the fuse holder.
Before replacing the fuse, turn off the
apparatus and disconnect the power
source.

Protective Grounding

Be sure to connect the protective grounding in
order to prevent an electric shock before

turning on the apparatus.
Never cut off the internal or external
protective grounding wire or disconnect the
wiring of the protective grounding terminal.

Operating Conditions

Do not expose to rain or moisture. Do not
immerse the appliance in water or any other
