Furman IT 20 II

Furman Sound announced a new 20-amp balanced isolation transformer that provides two levels of noise filtration for sensitive electronics and advanced protection against surges and overvoltages. With 80 dB of common-mode noise reduction and 40 dB of differential-mode noise reduction, the IT-20 II unveils important low-level signals, enabling high-end audio/video equipment to achieve their maximum performance.

The IT-20 II can supply 20 amps of balanced AC power with more than 80 dB of common-mode noise reduction from a frequency range of 20 to 20k Hz. One unique feature of the IT-20 II is its ground lift switch, which allows equipment plugged into the output of the unit to be 100-percent isolated on all three lines (hot, neutral and ground) from the input.

The IT-20 II is also equipped with Furman’s Series Multi-Stage Protection Plus (SMP+) circuitry, which includes Linear Filtering Technology (LiFT) that suppresses more than 40 dB of differential-mode noise consistently across the entire dynamic range. In addition, the circuit incorporates Series Multi-Stage Protection, which clamps and dissipates damaging transient voltages at the highest degree available without sacrificing any components, and Extreme Voltage Shutdown (EVS), which protects against accidental connections to 208 or 240 VAC by shutting off the incoming power until the overvoltage condition is corrected. These technologies ensure that expensive equipment is not destroyed by power problems.

The rackmount IT-20 II has a toroid transformer that contains its magnetic field so that other components can operate in close proximity. The unit provides 12 ultralow-resistance isolated Hubbell AC outlets in the back, plus two additional outlets on the front panel, all of which are GFCI-protected. A laboratory-grade digital voltmeter displays the incoming voltage on the front panel.
