IT-REFERENCE 20i is an exclusive Discrete Symmetrical Power product marketed by Furman. The range includes video screens, projectors, CD-DVD players, pre-amplifiers, and scalers. The power components marketed by Furman are linear-filtered and enhance performance via ultra-low-noise symmetrical power. In the bargain, the masked low level signals and content affect the harmonics, depth and clarity in any audio/visual display unit. These features of the IT-REFERENCE 20i technology reduce AC noise considerably.
