The Luxman K-351 is an auto-reverse stereo cassette deck that showcases advanced features for audio enthusiasts. Introduced in 1991 and priced at approximately $600, it offers functions such as Dolby B/C and HX-Pro noise reduction. The deck is equipped with a two-head design and features a digital tape counter with four digits, allowing users to track tape lengths and playback time easily. The K-351 is designed to automatically select the tape type, accommodating normal, chrome, and metal tapes. It utilizes a belt-driven auto reverse transport system, enabling seamless playback in both directions. The cassette compartment is positioned on the left side, and the mechanical tape eject mechanism requires the cassette to be inserted with the side to be played facing forward. The digital peak reading meters provide an accurate visual representation of audio levels, while full-logic transport controls ensure responsive operation. The Dolby C-type noise reduction system effectively minimizes background noise, and the Dolby HX Pro system enhances recording quality by optimizing bias control. The K-351 also features a switchable MPX filter to eliminate interference from FM stereo broadcasts. Additionally, it provides microphone inputs for live recording and a jack for headphones, making it versatile for both recording and playback purposes. RCA connections facilitate interaction with other audio components.
