AV-25K83, AV-21D83, AV-20N83 specifications

The JVC AV-20N83, AV-21D83, and AV-25K83 are part of JVC's renowned line of CRT televisions that offered a blend of advanced technology and consumer-friendly features. These models, although classic by today's standards, played a significant role in the evolution of home entertainment systems during their production era.

The JVC AV-20N83 is a 20-inch model that was designed with a compact footprint, making it ideal for smaller living spaces such as apartments and dorm rooms. It features a 4:3 aspect ratio, which was the standard for television programming at the time. This model incorporates JVC’s proprietary color technology, which enhanced picture clarity and vibrant color reproduction. Its built-in stereo sound system delivered clear audio, providing an immersive viewing experience that complemented the high-quality visuals.

The AV-21D83, a slightly larger 21-inch variant, built upon the strengths of the AV-20N83. This model was equipped with a range of connectivity options, including composite and RF inputs, making it suitable for various external devices such as VCRs and gaming consoles. The AV-21D83 also featured an enhanced audio system, allowing for a richer sound experience. One of its standout characteristics was the ease of operation. The user-friendly remote control made switching channels and adjusting settings simple, enhancing the overall user experience.

The AV-25K83, the largest of the three at 25 inches, was a compelling option for families looking to enjoy movie nights or gaming sessions. This model boasted advanced picture processing technology, ensuring high-quality images with minimal distortion. The 25-inch screen size offered a more immersive viewing experience, making it a popular choice for larger rooms. The AV-25K83 included features such as sleep timer and parental control settings, which catered to family needs and preferences.

All three models were equipped with JVC’s reliable build quality, ensuring durability and longevity.
