For over 33 years Furman has pioneered the development of AC power products for the most demanding audio video and broadcast professionals. Though the need for pristine AC power is nothing new the IT-REFERENCE 15i's technology and its unique implementation are revolutionary and without peer. The extreme AC demands encountered in the professional audio/ video arena have required technological developments far in excess of typical home theater/audiophile power products. In studios live sound and broadcast facilities breakdown is unacceptable. Equipment failure or poor performance is costly. The same is true of today's home theater. Our solution-based technology extensive engineering expertise and robust build quality have answered the challenge of today's corrupted power lines and led to the creation of the IT-REFERENCE 15i. The IT-REFERENCE 15i also features comprehensive virtually maintenance-free protection from voltage spikes and surges.
