INTRODUCTION

Thank you for purchasing a Furman Prestige Series Voltage Regulator/Power Conditioner, and congratulations on your choice.  The 
Prestige Series P-1400 AR E features Furman’s True RMS Auto Regulation, Series Multi-Stage Protection (SMP) circuit, and our exclusive 
Linear Filtering Technology (LiFT).  Together, these technologies comprise precisely what our customers have grown to expect from 
Furman: uncompromised protection and purification.  The P-1400 AR E has been precisely engineered to more than meet the critical 
demands of recording studios, broadcast facilities, and discerning musicians alike.   

The Furman P-1400 AR E is intended to protect sensitive electronic equipment from problems caused by AC line voltage irregularities—
brownouts or over-voltages that can cause audio tonal changes, digital equipment malfunction (such as loss of MIDI programs or other 
data), or, in extreme cases, permanent damage. It accepts input voltages between 188V-270V and converts them to a steady, stable 
output of either 230V or 240V (switchable), plus or minus 10 volts. Voltages approximately ±10% beyond that range may be converted 
to usable levels, depending on the requirements of the equipment. This stable voltage protects equipment and allows optimal 
performance. If you frequently move your rack to different locations, derive power from generators, use excessively long extension 
cords, travel internationally, or are in an area prone to brownouts, you will benefit from the use of a Furman P-1400 AR E.  

DESCRIPTION

True RMS Voltage Regulation Technology

True RMS Voltage Regulation is designed around an ultra-low noise eight-tap toroidal autoformer.  A microprocessor within the P-1400 
AR E monitors the incoming RMS voltage with each cycle, measuring the phase angle in time with the advancing cycle.  Most com-
mercial voltage regulators using multiple-tapped transformers switch taps at uncontrolled times. This creates voltage spikes and clicks 
that can leak into audio. When a voltage fluctuation requires correction by the P-1400 AR E, True RMS Voltage Regulation advances a 
new tap with less stress and in turn avoids distortion to the AC waveform. Hysteresis in the P-1400 AR E circuits avoids the unneces-
sary switching back and forth between the adjacent taps (or “chatter”) found in many commercial voltage regulators. If necessary, 
True RMS Voltage Regulation technology can switch taps as often as once each cycle and do so with a shorter recovery time than a 
commercial voltage regulator. In addition and unlike voltage regulators that employ ferroresonant transformers, the P-1400 AR E is not 
sensitive to small errors in line frequency, making it ideal for use with generators.
The P-1400 AR E has ten outlets on the rear panel and one convenience outlet on the front panel. All are functionally interchangeable. 
The outlets are regulated, surge-suppressed, and linearly filtered, making the unit a full-function power conditioner. The autoformer’s 
toroidal design assures minimal leakage of stray magnetic fields.  

Note:

P-1400 AR E is for use with AC voltage only. DC voltages should never be applied. Also, it does not change or regulate line  

Frequency. The output frequency will always be the same as the incoming frequency. 

SMP (Series Multi-Stage Protection) with EVS (Extreme Voltage Shutdown)

Furman’s SMP (Series Multi-Stage Protection) surge suppression virtually eliminates service calls and costly “down time”.  Traditional 
surge suppression circuits sacrifice themselves when exposed to multiple transient voltage spikes, requiring the dismantling of your 
system and repair of your surge suppressor.  Not so with Furman’s SMP.  With SMP, damaging transient voltages are safely absorbed, 
clamped, and dissipated.  Your connected equipment is protected, while your P-1400 AR E protects itself!
