Most CTs were 20-inch, 24-inch and 25-inch TVs.
One of Panasonic's economy series of televisions in 1993 was the "CT." At the time, few consumer flat-panel displays were available. The technology was cathode-ray tube, which required larger and heavier models. The CT series was available in sizes of 36, 34, 32, 27, 25, 24, 20 and 13 inches. According to Panasonic, the 20-inch models were designed specifically for use in hotels.
Features
All Panasonic TVs sold in North America were powered with 120 volts AC 60 Hz. The available channels were VHF 2-13, UHF 14-69 and cable 125. TVs of that time were not digital; they received and broadcast analog signals. Most of the TVs had three video and three audio input jacks. The TVs were all stereo sound with spatializer surround sound. All the models had closed-caption display.
Picture Options
All Panasonic TVs from 1993 allowed the user to adjust color, tint, brightness, picture and sharpness. Some models offered color temp, video noise reduction and auto color. Color temp would change the tint of the picture; a bluish tint would be cool while a reddish tint would be warm. Video NR reduced the amount of static, snow or noise displayed. Digital TV has eliminated the need for video NR.
Audio Options
Most Panasonic TVs from 1993 allowed the user to control bass, treble and balance and allowed users to switch between stereo, second audio program and mono. Some TVs featured spatializers and AI sound. The spatializer makes the normal stereo sound more real, as if more speakers are being used. This process is called "Psycho-Acoustic." AI sound normalizes the volume between channels and programming so the sound level is consistent.
