The Qv2 is designed to enhance the musical performance and picture quality of any audio or video system, delivering readily demonstrable benefits at an incredibly affordable price.  It can be used as a "stand alone" product or to complement a full QRT system with a Q-base and QX2 or QX4. The Qv2 works directly on the AC line, introducing a carefully calculated range of pulsed frequencies, clocked from the original 60 Hz waveform. The result is a drop in noise floor, with a commensurate increase in image depth, dimensionality and presence, significantly increasing the realism of both musical and visual performance. Like other QRT products, the benefits are cumulative and Qv2's are even more impressive when used en masse.
