The Sony TC-KB820S is a vintage portable cassette player and recorder from the 1980s. It is a part of Sony's KB (karaoke broadcasting) series and was designed specifically for use at karaoke bars and music studios. Some of its notable features include:1. Dolby C noise reduction: This technology helps to reduce background noise in recorded cassettes, making them sound clearer and more crisp.2. Built-in Karaoke mode: This mode allows you to remove the lead vocals from pre-recorded music, leaving only the instrumental track behind. This feature was especially popular in karaoke bars, as it allows singers to sing along to their favorite songs using the included microphone.3. Large 120mm full-frequency speaker: This speaker provides clear and powerful audio output, making it ideal for use at loud venues like karaoke bars and music studios.4. MPX format: The MPX format, also known as reinforced stereo, was designed specifically for karaoke use. It provides enhanced left and right stereo channels, making it easier for singers to hear their own voices over the music.5. 3-speed playback: This feature allows you to adjust the speed of the playback to match the singer's vocal range, making it easier for them to hit the right notes.Overall, the Sony TC-KB820S is a highly specialized device designed for use in karaoke venues and music studios. Its unique features and high-quality audio output make it a popular choice among karaoke enthusiasts and musicians alike. However, it may not be as relevant today, as digital karaoke machines and software have largely replaced the use of cassette players in these settings.
