INTRODUCTION
Thank you for purchasing a Furman Prestige Series Voltage Regulator/Power Conditioner, and congratulations on your choice. The
Prestige Series P-2400 AR features Furman's True RMS Voltage Regulation, Series Multi-Stage Protection (SMP) circuit, and our exclu-
sive Linear Filtering Technology (LiFT). Together, these technologies comprise precisely what our customers have grown to expect from
Furman: uncompromised protection and purification. The P-2400 AR has been precisely engineered to more than meet the critical
demands of recording studios, broadcast facilities, and discerning musicians alike.
The Furman P-2400 AR 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 over a wide AC voltage range and converts them to a steady,
stable output of 120V, plus or minus five volts. Voltages approximately ±10% beyond the capture 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 inter-
nationally, or are in an area prone to brownouts, you will benefit from the use of a Furman P-2400 AR.
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-2400
AR monitors the incoming RMS voltage with each cycle, measuring the phase angle in time with the advancing cycle. Most commer-
cial 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-2400 AR, True RMS Voltage Regulation advances a new tap
with less stress and in turn avoids distortion to the AC waveform. Hysteresis in the P-2400 AR circuits avoids the unnecessary 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-2400 AR is not sensitive to small er-
rors in line frequency, making it ideal for use with generators.
The P-2400 AR has twelve outlets on the rear panel and two convenience outlets on the front panel. All are functionally interchange-
able. The outlets are regulated, surge-suppressed, and linearly filtered, making the unit a full-function power conditioner. The auto-
former's toroidal design assures minimal leakage of stray magnetic fields.
Note: P-2400 AR 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-2400 AR protects itself!
Unique to Furman's SMP is its unparalleled clamping voltage. While other designs offer clamping voltages that are well above 330
Vpk, Furman's SMP clamps at 188 Vpk, (133 V RMS) even when tested with multiple 6000 Vpk - 3000 amp surges! This unprecedented
level of protection is only available with Furman's SMP technology. Additionally, Furman's trusted EVS (Extreme Voltage Shutdown)
circuitry protects against catastrophic overvoltage conditions (such as all-too-frequent accidental connections to 208 or 240 VAC or an
