Symptom
Likely Cause
What to do
Speaker not connected to active AC power
Verify that speaker is connected and that the circuit is on
Power not switched on
Switch on power and verify that power Led is on
Speaker power cable is faulty or omproperly
connected.
*Re-seat theh power cable at both ends;
*Substitute a known-good power cable
Blown fuse
*Check fuse and replace with same type "spare fuse in holder"
Signal source(mixer, instrument, etc) is not
sending
*Check VU meters on the source mixer;
*Verify that the tape or CD is playing;
*Use headphones to verify that the instrument is actually sending an
audio signal
Faulty cables and connections
*Disconnect and re-seat signal cables;
*Replace suspected cable with a known-good cable
No sound with microphone
connected directly to the
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 and
external phantom power supply for condenser type microphones.
Signal sounds distorted and
very loud, LIMIT light is lit
most of the time
Excessive input signal, rying 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
Signal sounds distorted
even at moderate vlumes,
LIMIT light is nong lit
Mixer or other source is overdriven
Review the Owner's Manual for yout mixer and adjust controls as needed.
*Input sensitivity(gain);
*Channel faders;
*Master faders once this is done, review the instructions in the Quick
Start section of this guide.
Lots of hisee in the sound,
the mixer controls are at very
low settings.
Inproper gain structure
*Make sure that the MIC/LINE switch is in the LINE(disengaged)position;
*Reduce the level settings at speaker, Review the Owner's Manual for
yout mixer and adjust controls as needed;
*Input sensitivity(gain);
*Channel faders;
*Master faders;
Noise or hiss heard at output Noisy source device
Disconnect the devices that are connected to yout speaker one at a time.
If the noise goes away, the problem is with the source or the connecting
cable.
Improper A/C ground or faulty equipment
connected to mixer input
Disconnect or mute channels on at a time to isolate the problem. Refer to
the owner's manual of the faulty equipment for trouble shooting help.
Faulty cable between source equipment and
mixer
Substitute a known-good cable for the suspected faulty cable.
Improper A/Cgounding, ground loops
*"lift" the audio ground by using an XLR/F to XLR/M adapter on one end.
*Re-route audio cables away from AC power and lighting cables.
Excessively long unbalanced cable run
*Use the balanced outputs(if available)of yout mixer or source equipment
to drive your EON speakers.
*Use a "DI"(direct injection) box to convert your unbalanced equipment
output to a balanced output.
Improper system gain structure
Reduce the INPUT level controls and increase the output level of your
source devices.
The inputs from INPUT 1 and
INPUT 2 aren't coming out of
the OUT connector
MIX/LOOP SWITCH set improperly
Set the MIX/LOOP SWITCH to the MIX position(depressed)
The speaker connected to
the OUT connector goes up
involume when I adjust the
INPUT 3 control on the first
speaker
MIX/LOOP SWITCH set improperly
Disengage the MIX/LOOP OUT switch, set to LOOP.
Microphone are pointed into the speakers
Move thespeakers so they do not point at the microphone's pickup
pattern.
Equializer settings are incorrect
Locate the feedback frequency and reduce it using the mixer EQ or an
external equalizer.
Excessive gain
Reduce the gain at the mixer and move the micronphone closer to the
sound source.
Hum or Buzz
Speakers feed back and howl
when the micronphone
volume is truned up
No sound
No sound, speaker is
connected to working AC
power but won't come on
No sound. Speaker cones on
Hum ot Buzz that increases
or decreases when the mixer
level controls are moved.
