Tenuous

He realized his grasp on the technology was tenuous. Everything was HDMI; analog (which he’d understood) was dead as a dodo. The hook-up options were impenetrable, the manual no help. From cable box to TV, or through the amp then to the TV? The Blu-ray (already obsolete) had to connect somewhere, too. The speakers were wireless and needed their own power source. When everything ran it’d draw about a kilowatt – if he ever got it running.
