Technics SH-3066 (1983)
The SH-3066 is a compact audio-video selector from Technics, released in 1983 and listed at ¥34,800 in Japan. It sits at the center of an AV stack and switches both picture and sound between up to six components.
Video routing covers two VCRs, a TV, and a video disc player. The monitor output is 1 Vp-p into 75 ohms, and there are VHF antenna in/out terminals too. The audio side handles line sources, tape, and the two VCRs. It is rated at 150mV input/output, 0dB gain, 22kΩ input impedance, and 600Ω output impedance. The feature list mentions a "DA Processor with Digital Copy Input" - a label suggesting early digital-audio copying capability. No deeper explanation of that circuit appears in the surviving record. No THD, frequency response, or S/N figures are documented either.
It's a low-slung box: 430mm wide, 53mm high, 157mm deep, weighing 1.9kg and drawing 9W from a 100VAC line. One manual archive offers free downloads for the user, service, repair, and parts-list manuals, and labels the unit "music Center" - likely a translation quirk. Beyond that, the record is thin. No period reviews or owner reception have surfaced so far.
