Panasonic CT-9R11A

Quick view

The Panasonic CT-9R11A is a CRT (Cathode Ray Tube) television released in the late 1980s. It features a 9-inch diagonal screen with a standard definition display supporting NTSC signal format for North American regions. The device includes composite video input and RF tuner allowing reception of analog broadcast channels. The CRT technology provides a resolution suitable for standard TV shows and basic video playback during its time. It supports mono audio output with basic volume and channel controls via built-in analog tuning. Power consumption is typical for CRT TVs of the era, requiring a mains voltage power source.

Its build includes a compact chassis designed for tabletop placement. The picture tube uses shadow mask technology to create color images with electron beam scanning. The device lacks digital interfaces or advanced connectivity options common in modern televisions. Its operation relies entirely on analog circuitry for signal processing and display output.

The CT-9R11A offers a compact and lightweight form factor suitable for small spaces and portability. Its 9-inch CRT screen delivers vivid color reproduction using traditional cathode ray tube technology. The TV includes a built-in RF tuner, enabling reception of standard UHF and VHF analog broadcast channels without external tuners. It provides user-friendly manual channel selection and volume adjustment controls. The composite input allows connection to external video sources such as VCRs and gaming consoles of that era. Additionally, its durable build quality ensures long-lasting performance under typical usage conditions.

As a CRT-based television, the CT-9R11A is limited by lower resolution and bulkier design compared to modern flat-panel displays. It supports only analog NTSC signals, making it incompatible with current digital broadcasting standards without converter boxes. The screen size is relatively small at 9 inches, reducing viewing comfort for larger rooms. Its mono audio output restricts sound quality and stereo playback capabilities. The absence of remote control and limited input options constrain usability and connectivity. Moreover, the device generally consumes more power than modern energy-efficient TVs.
