Congratulations on your purchase of
a Furman AR-1220 AC Line Voltage
Regulator. The AR-Series regulators
are designed specifi cally for any audio,
video, or computer rackmount system
requiring clean, fi ltered, and regulated
AC power for optimum operation.
Nominal output voltages vs.
Usable range for most equipment is an
additional 10% above and below the
capture ranges shown in the table Ten
LED bar graphs for Input Voltage and
Output Current Extreme overvoltage or
undervoltage causes instant shutdown,

20A outlets on the back panel, two 15A
Fast acting user accessible circuit break-

AR 1220J NOTE: FIRST SELECT
Before using your model AR 1220J Voltage Regu-
lator, be sure that the output voltage switch on
the rear panel is correctly set for the AC voltage
required by your equipment Each item of equipment
that you intend to power with the AR 1215J Voltage.
Regulator should have its required voltage indicated
on it, usually on the rear near the cord. If in doubt,
Furman Voltage Regulators are intended to pro-
tect sensitive electronic equipment from problems
caused by AC line voltage ir-regularities brownouts
or overvoltages that can cause audio to-nal chang-
es, digital equipment malfunction (such as loss of
MIDI programs or other data), or, in extreme cases,
permanent damage. They accept input voltages
over a wide AC voltage range (see table at left) and
convert them to, and stabilize them at, the desired
national voltage standard, ±5V. Voltages approxi-
mately ±10% beyond that range may be converted
to usable levels, depending on the requirements of
