Ultra-Low Resistance Magnetic Power Switch / Circuit Breaker:

Furman's Prestige Series 30 amp capacity power switch / circuit breaker is specifically designed to stand up to the enormous high

in-rush current demands of many power amplifiers. If the 30 amp maximum RMS current capacity of the P-6900 AR E is exceeded,

the spring tensioned switch will immediately reset to the "0" position. You will need to switch back to the "1" position once the

problem is corrected (typically by eliminating one component), or until the RMS current does not exceed 30 amps (6900 watts @

230VAC).

Total Current Capacity (maximum and minimum load):

The P-6900 AR E can handle loads totaling up to 30 amperes as long as the input voltage is equal to or above 230 volts (or; 240V

with the 240V output setting). For voltages below that level, its capacity must be de-rated at approximately 130 milliamperes per

volt. (See graphs on back page.) As a practical matter, therefore, to cope successfully with worst-case brownout conditions, you

should plan your total load so that it does not exceed approximately 25 amps, or 5800 watts. Please note that this refers to the ag-

gregate power requirement of all equipment plugged into the P-6900 AR E, not to each individual item.

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 300+ VAC where 230VAC is expected, or an open series neutral from a multi-phase 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-6900 AR E, 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-6900 AR E's outlets. If the unit has been

operating with an acceptable input voltage and subsequently that voltage exceeds 275V, 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-6900 AR E'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.

Note: As there are currently different charging standards for USB devices, some devices may not be compatible with our charger.

Isolated Outlet Banks:

The Furman P-6900 AR E features six rear-panel IEC-320 10 Amp outlets in two isolated banks. If you are connecting digital and ana-

log equipment to the P-6900 AR E, it is recommended to connect the analog equipment to "Bank A" and digital equipment to "Bank

B" (or vice-versa) to minimize electrical crosstalk.
