Discrete Symmetrically Balanced Power

The balance of power.

Many of Furman products include isolation transformers that utilize Dual Screen Technology that yields the widest bandwidth of noise reduction available on the market.

Differential AC noise (electromagnetic and RFI) can be effectively reduced with a low-pass filter such as Furman LiFT, but common mode AC noise, (the cause of ground loops and video hum bars) requires more advanced solutions. The most effective solution is deployment of true symmetrically balanced isolation transformers. You can count on balanced power when you count on Furman products.

Furman Discrete Symmetrically Balanced Power is achieved by running the incoming AC into a 1:1 isolation transformer with a precisely placed center tap on the transformer’s secondary.

The incoming voltage (120V on the line terminal and 0V on the neutral and ground) is split into perfect halves on the transformer’s output. The AC line now has 60V on the line and 60V on the neutral when referenced to the new center-tapped ground, which remains at 0V AC.

Furman isolation transformers utilize Dual Screen Technology, which yields the widest bandwidth of noise reduction available. This allows Furman Discrete Symmetrically Balanced Power units to uncover unprecedented levels of video and audio detail while ensuring that flat panel displays or video projectors are free of AC ground contamination from an audio processor or power amplifier.

What is significant about this is that the two 60V AC terminals are now in opposite polarity. This completely cancels all common mode noise from the incoming AC line. This noise reduction is extraordinarily efficient and linear across a huge frequency range, and the result is perfectly clean power devoid of ground loops and AC hum noise.
