Sanyo Flot MR-C02 (1984) – A Visionary Modular Portable Audio Prototype

 

In 1984, Sanyo unveiled an intriguing prototype that showcased its vision for the future of portable audio systems — the Sanyo Flot Separate System Radio Cassette Recorder MR-C02. This futuristic concept represented a bold step toward modular and flexible design, long before such ideas became mainstream. The Sanyo Flot MR-C02 was built around a central control unit featuring a radio tuner, a detachable cassette deck, and a graphic equalizer for fine-tuning sound performance. On each side of the main body, two detachable stereo speakers completed the system, allowing users to enjoy both portability and a wider, more immersive stereo soundstage. For convenience, the central unit could be tilted upward for better visibility of controls, while the speakers could either be attached for a compact, all-in-one boombox style, or separated to create a true stereo setup. Sanyo promoted this concept as a “floating audio system,” a reference to its sleek, balanced design and modular “floating” components. Although the Sanyo Flot MR-C02 never reached mass production, it remains a fascinating glimpse into 1980s Japanese audio innovation — a perfect example of Sanyo’s experimental spirit during the golden era of portable cassette technology.
