to avoid distorting the AC waveform. If necessary, it
can switch taps as often as once each cycle. Some
commercial voltageregulators using multiple-tapped
transformers switch taps at uncontrolled times,
thereby creating voltage spikes and clicks that can
leak into the audio! Hysteresis in the switching cir-
cuits avoids “chatter” or unnecessary switching back
and forth between adjacent taps. And unlike voltage
regulators that employ ferro-resonant transform-
ers, Furman Voltage Regulators are not sensitive to
small errors in line frequency, making them ideal for
use with generators.
SUPPLY CABLE WIRING
The AR-1230’s rear panel provides a NEMA L14-30R
male inlet connector; a NEMA L14-30P cord mounted
female connector is included with the unit. Please
refer to the “Rear View” wiring diagram at below.

It is essential that all equipment powered by an AR-
1230 be properly grounded! Never cut off the power
cord ground pin or use a “cheater” adaptor on any of
your equipment!
INSTALLATION
The AR-1230 is designed for mounting in a standard
19-inch rack. Because of its weight, the best position
for it is at the bottom of the rack. Its toroidal trans-
former minimizes magnetic leakage, but neverthe-
less, due to its high capacity, it can radiate an appre-
ciable magnetic fi eld. Therefore, we recommend that
it not be positioned adjacent to sensitive, low level
signal processors, especially mic preamps, mix-
ers, tape recorders, etc. Power amps may be more
suitable “rack neighbors.” As with any rackmount
equipment, be sure to use 10-32 machine screws
for mounting in the rack’s tapped holes, and to avoid
marring the front panel fi nish, use plastic washers
under the screw heads.
ONE YEAR LIMITED WARRANTY
Furman Sound, Inc., having its principal place of busi-
ness at 1997 South McDowell Blvd., Petaluma, CA
94954 (“Manufacturer”) warrants its AR-1230 (the “Prod-
uct”) as follows:
Manufacturer warrants to the original Purchaser of
the Product that the Product sold hereunder will be free
from defects in material and workmanship for a period
of one year from the date of purchase. The Purchaser
of the product is allowed fi fteen days from the date of
purchase to complete warranty registration by mail or
on-line at the Furman website. If the Product does not
conform to this Limited Warranty during the warranty
period (as herein above specifi ed), Purchaser shall notify
Manufacturer in writing of the claimed defects. If the
defects are of such type and nature as to be covered by
this warranty, Manufacturer shall authorize Purchaser to
return the Product to the Furman factory or to an autho-
rized Furman repair location. Warranty claims should be
accompanied by a copy of the original purchase invoice
showing the purchase date; this is not necessary if the
Warranty Registration was completed either via the
mailed in warranty card or on-line website registration.
Shipping charges to the Furman factory or to an autho-
rized repair location must be prepaid by the Purchaser of
the product. Manufacturer shall, at its own expense, fur-
nish a replacement Product or, at Manufacturer’s option,
repair the defective Product. Return shipping charges
back to Purchaser will be paid by Manufacturer.
THE FOREGOING IS IN LIEU OF ALL OTHER
WARRANTIES, EXPRESS OR IMPLIED, INCLUDING
BUT NOT LIMITED TO THE IMPLIED WARRANTIES
OF MERCHANTABILITY AND FITNESS FOR A PAR-
TICULAR PURPOSE. Manufacturer does not warrant
against damages or defects arising out of improper or
abnormal use of handling of the Product; against defects
or damages arising from improper installation, against
defects in products or components not manufactured by
Manufacturer, or against damages resulting from such
non-Manufacturer made products or components. This
warranty shall be cancelable by Manufacturer at its sole
