into sensitive lines, particularly low level and unbalanced sources.  
FEATURES  
The IT-1210, IT-1220 and IT-1230 not only dramatically  
reduce the noise floor but also have been reported to noticeably  
improve dynamic range and sonic clarity.  
Available in 10 Amp, 20 Amp and 30 Amp models  
Provides precisely balanced AC power for ultra-low-noise  
installations  
Typically gives a 16 dB improvement in background noise  
floor  
Toroidal transformer with center-tapped secondary is the  
most efficient and compact design, with minimal magnetic  
field leakage  
At the heart of these units is a specially wound and shielded  
toroidal isolation transformer with a center-tapped secondary.  
These precision transformers, in conjunction with wideband  
EMI/RFI filters and output spike protection, make these units  
excellent power conditioning solutions for any situation.  
Exclusive “Soft Start” circuit prevents turn-on transients  
and high inrush currents  
Faraday shield reduces electrostatic coupling between  
primary and secondary  
Extreme Voltage Shutdown circuit protects against  
dangerously high or low input voltages  
An IT-1210 or IT-1220 can be installed in minutes without the  
need for an electrician; the IT-1230 may require some help in  
choosing and wiring an appropriate supply cable. All three models  
provide clean and completely safe power – there is no need to  
“lift grounds” or compromise the integrity of safety ground wires to  
achieve hum reduction.  
Microprocessor-controlled “smart” AC voltmeter monitors  
line voltage, flashes alerts for marginal and extreme  
conditions  
Provides basic power conditioning (spike suppression, RFI  
filtering) plus gas discharge tube to dissipate spikes  
Ground fault circuit interrupter (GFCI) protection  
Models IT-1210 and IT-1220 UL/CUL listed  
Special features include an accurate, self-checking AC  
voltmeter that not only measures normal voltages, but also  
flashes eye-catching special pattern alerts for off-scale but not  
extreme conditions (80-90 or 130-140 Volts); an Extreme Voltage  
Shutdown circuit to cause a protective shutdown if the unit is  
exposed to dangerous voltages (like accidental connection to 220  
Volts); and Furman’s exclusive “Soft Start” circuit to prevent the  
large inrush surge currents and spikes that would otherwise occur  
at turn-on and turn-off with such large transformers.  
The IT-1210 occupies two rack spaces (3.5" high); the IT-1220  
and IT-1230 occupy three rack spaces (5.25" high).  
DESCRIPTION  
Designed for the most critical, ultra-low-noise installations,  
the IT-1210, IT-1220 and IT-1230 can supply 10, 20 or 30 Amps  
of balanced AC power to recording studios, video or film  
production facilities, broadcast stations, etc. These models  
drastically reduce hum and buzz caused both by ground currents  
from power supply filtering and by radiation from supply cables  
The IT-1210 and IT-1220 rear panels provide 12 outlets, the  
front panel provides two. The IT-1230 rear provides ten 20 Amp  
outlets, one 30 Amp twistlock outlet and one 30 Amp twistlock  
inlet. The front provides two 15 Amp outlets. All outlets are  
balanced and Ground Fault Circuit Interrupter protected.
