from the unit when the POWER switch is on with nothing plugged in. This effect will sometimes disappear as soon as you plug in any
equipment drawing 40 to 50 watts total.
Extreme Voltage Shutdown Indicator:
The Extreme Voltage LED indicator is normally off. It is located within the meter lens assembly directly above the blue voltage me-
ters LED's, though during normal use it will NOT be visible.
The Extreme Voltage indicator monitors a hazard common in the entertainment industry, as well as remote broadcast: wiring faults,
such as accidental connection to 208VAC where 120VAC is expected, or an open series neutral from a 208 to 240VAC electrical ser-
vice. The Furman EVS circuit senses voltages that are so high that operation would be impossible and shuts the power down before
damage can occur.
Upon initially applying power to the P-2400 AR, the Extreme Voltage indicator will illuminate to a bright red if the input voltage
is above the extreme voltage cutoff. When this occurs, power will not be applied to the P-2400 AR's outlets. If the unit has been
operating with an acceptable input voltage and subsequently that voltage exceeds 140V, it will shut off power to the outlets and the
Extreme Voltage LED will light.
NOTE: If the mains power is above the high cutoff voltage and has caused the EVS circuit to remove power from the Furman's
outlets, it cannot restore power without the operator manually turning the unit off, then on again. Avoid turning the unit back on
without first checking the source of the problem and perhaps changing the AC source.
Protection OK Indicator:
Although the Furman SMP circuit assures virtually maintenance free protection from transient voltage spikes and surges, nature has
a way of occasionally creating electrical forces that are beyond the capabilities of any TVSS device to absorb without some degree
of damage (such as a direct lightning hit in an outdoor application). In the rare instance that this occurs, the green "Protection OK"
LED indicator (located to the lower right of the voltage meter) will not illuminate. If this happens, some level of protection from
voltage surges will remain, but the Furman's clamping voltage rating will be compromised. The unit must be returned to Furman.
USB Charger:
The Furman P-2400 AR's USB charger provides an easy way to recharge many popular electronic accessories as well as cellular
communication devices by simply plugging the re-charge cord into the front panel socket. Please note: as there are currently many
standards for USB, some devices may not be compatible with our charger.
Isolated Outlet Banks:
The Furman P-2400 AR features twelve rear-panel outlets in 2 isolated banks. If you are connecting digital and analog equipment to
the P-2400 AR, it is recommended to connect the analog equipment to "Bank A" and digital equipment to "Bank B" (or vice-versa)
to minimize electrical crosstalk. The two front panel convenience outlets deliver all of the protection, filtration and regulation ben-
efits of the rear panel outlets, and are functionally part of "Bank B".
TROUBLESHOOTING
1.) Symptom: No power to the AC outlets; "Protection OK" indicator is not lit.
Possible Cause: Either the AC outlet to which your P-2400 AR is connected has no AC voltage present, or there has been damage to
the unit's circuitry.
Action Needed: Plug the P-2400 AR into an AC receptacle where a nominal 120 VAC is present. If the problem persists, the internal
circuitry may be damaged and the unit will require factory service (see "Service" section below).
2.) Symptom: Extreme Voltage indicator lit.
Possible Cause: Input voltage is above 140 volts causing power to the unit's outlets to be shut down.
Action Needed: Correct the line voltage, and then turn the Furman conditioner on.
SERVICE
Questions or issues with your Furman unit should be directed to the Furman Customer Service Department, available 8AM-4PM Pa-
cific Time at (877) 486-4738 or via email at info@furmansound.com. If a unit requires service, it must have an RA number assigned
from Furman's Customer Service Department.
Before returning any equipment for repair, please be sure that it is adequately packed and cushioned against damage in shipment,
and that it is insured. We suggest that you save the original packaging and use it to ship the product for servicing. Also, please en-
