JVC HRS-6700U (c. 1981)
Surviving documentation on the JVC HRS-6700U is thin, and what exists calls it the HR-6700U. The most substantial record is an equipment profile in Audio (April 1981, p.56). It called the deck JVC's finest VCR to date for picture reproduction, special-effects capabilities, and programming facilities. The same profile printed the manufacturer's specifications, and those are the only confirmed specs known for this deck. Earlier, in the March 1981 issue's "Video Scenes" column, Bert Whyte noted that the HR-6700U allowed manual pretuning of each channel. He said this gave a sharper picture than automatic tuning alone. The profile also credited the deck with automatic playback-speed sensing - it would detect the speed a tape was recorded at and switch playback speed automatically. It also had a tuner that could preset up to 12 VHF or UHF channels with numbered labels.
Known specifications from the April 1981 profile:
- Format: VHS
- Maximum recording time: 2 or 6 hours on a T-120 cassette
- Audio signal-to-noise ratio: better than 40 dB
- Audio frequency response: 50 Hz–10 kHz
- Antenna input: 75-ohm VHF (unbalanced); 200-ohm UHF (balanced)
Beyond these period mentions, no service literature, price sheets, or further reviews have surfaced in the archive.
