Birth of MD Base

Introducing a groundbreaking concept, the composite model combines a Station with an MD Walkman. On-the-go, it serves as a portable MD, while at home, combined with the Station, it transforms into a mini audio recorder.

The R4ST incorporates a slim replication head mechanism and a 4-layer printing machine, enabling highly integrated circuitry. Compared to its predecessor, the MZ-R3, it achieves a volume reduction of -26% and a weight reduction of -21%, marking the thinnest (23mm) and lightest model of the year. However, the Walkman itself can only record with a microphone (a minor shortcoming?), while recording through the Optical/Line interface requires connection with the Station.

The R4ST is Sony's first dual LCD (main unit + remote control) Recorder. The remote control also begins supporting kana display.

The battery life, approximately ↑200% compared to previous models when fully charged, reaches up to 10.5 hrs in simultaneous use.

The well-planned Station boasts a large backlit screen that even puts professional recording stations to shame, displaying approximately 80 characters at maximum. It simultaneously shows disc information, track names, controls, total tracks, recording levels, and more without needing to switch—an exceptional display capability.

The Station is equipped with shortcut keys for commonly used functions such as display, track marking, navigation, and deletion, providing an efficient and intuitive user experience. Additionally, it features thoughtful extra battery storage on the right side, allowing for direct charging.

With a comprehensive set of digital and analog input/output terminals, the editing and expansion capabilities are exhaustive, making it a fully-equipped arsenal. Moreover, it marks the first inclusion in the Sony MD Walkman series of built-in digital sampling, allowing direct recording of digital audio sources at different frequencies via the Optical interface.
