Voltage Selection And Fuses

Changing Voltage

Your EON Sub G2 will typically be set at the factory to accommodate the power mains voltage in
your area. Before you set up your EON Sub G2 for the first time it is a good idea to verify that the
setting of the selector is appropriate for the power in your area. Directly below the IEC power con-
nector you will see a seal that indicates the factory setting for the voltage. If the voltage indicated is
correct for your area, go ahead and power up your EON Sub G2.
In the event that you do need to change the voltage:
• Make sure that the AC is disconnected from the speaker.
• Directly below the male IEC connector on the speaker is a voltage selector. Break the factory-
applied seal.
• Set the voltage selector switch to the 115V or 230V setting as required for your area.
• After having reconfirmed that the correct voltage is selected, connect the AC (IEC connector)
and power the unit up.
DO NOT UNDER ANY CIRCUMSTANCES OPERATE THE UNIT WITH THE WRONG VOLTAGE
SELECTED. DOING SO MAY RESULT IN SERIOUS DAMAGE TO YOUR SPEAKER SYSTEM
WHICH WILL NOT BE COVERED BY WARRANTY.

Fuse Replacement

The EON Sub G2 has no user-serviceable fuses. Failure of fuses is most frequently a symptom of
problems requiring service by a competent technician.

Speaker power cable is faulty
or improperly connected.
Blown fuse.
Signal source (mixer,
instrument, etc.) is not
sending.
Faulty cables and
connections.
Excessive input signal, trying
to exceed the capabilities
of the speakers.
What to do
Verify that speaker is connected
and that the circuit is on.
Switch on power and verify that
power LED is on.
• Re-seat the power cable at both
ends.
• Substitute a known-good power
cable.
• There are no user-serviceable
fuses in the EON SUB G2. Take
your speaker to a competent
servicer.
• 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.
• Disconnect and re-seat signal
cables.
• Replace suspected cable with a
known-good cable.
• Reduce the output level of the
source.
• Turn down the LEVEL controls on
the speaker.
• Use additional EON speakers.
