That is, VHS stereo decks play VHS mono, and VHS HiFi decks play VHS stereo and mono. 2) Both formats have comparable HiFi specs to those of professional quality 30ips reel to reel analog tape recorders. Both HiFi Beta and VHS formats are essentially identical in audio performance. 3) The video bandwidth of BOTH formats approaches 2MHz, terrible by today's standards for video monitors that already have bandwidths of 4MHz and better. (What consumer deck regardless of format can boast 0dB at just 2MHz? Most measure -6dB or worse at this point.) 4) The reason that there are few VHS HiFi tapes is because of the age of this format, not the type of format. VHS HiFi is new and manufacturers respond cautiously to new innovations. (It has taken over two years for audio Compact Disc player titles to reach the 2,000 plus mark with a large percentage of these being released in just the past 6 months.)
