Furman IT-1220 Balanced Isolation Transformer Power Conditioner Rack Mount

With the flick of a switch (literally!), the Furman IT-1220 will supply you with 20 amps of balanced AC power. Perfect for a recording studio, video or film production facility, broadcast station, outdoor music venue, and more, this power condition is made to drastically reduce the hum and buzz you would typically get from the noise floor. Since it improves the dynamic range and sonic clarity, you'll get better sound than you ever thought possible.

Housed in a 3-unit rack chassis, the front panel provides two balanced outputs and the back panel provides an incredible 12 more. The IT-1220 offers that clean, safe power you need when operating multiple systems. It even has some awesome features like a self-check AC voltmeter, an Extreme Voltage Shutdown circuit, and a unique "Soft Start" circuit to prevent large inrush surge spikes that would otherwise occur in such a large transformer when it's turned on and off. Complete with a sleek black front panel, this heavy (66 lbs!) beast of a power conditioner is just what you need to protect against unwanted noise and surges.
