UPC-HB Power Center
need to do is have it plugged into an AC power source and powering a piece of equipment.
Expectations are a funny thing. If you are not expecting much, you’re usually quite happy with any result
at all and the opposite is equally true. The UPC-HB will lower the apparent noise fl oor of recordings,
improve the harmonic structure of instruments, increase depth and ambience and for video, improve
black levels and color saturation. If you expect 1000 veils to be removed from your system, or the
picture to magically become three dimensional, you’ll most likely be disappointed. The improvements
are subtle to dramatic depending on your system’s resolving power and program material. We suggest
you listen for signs of improvement on music featuring non-complex music containing a lot of upper
harmonics, such as acoustic guitar, piano, human voice, light orchestral pieces.
Video will also have a lower noise fl oor and this will be displayed as apparent blacker blacks, richer
colors and a more three dimensional image. Again, these can range from subtle to dramatic depending
on the quality of the power line in the fi rst place and the resolution of the video source.
