Brand: Sony
The Sony ST-S390 is a wireless tabletop speaker system that was released in the late 1990s. It uses Sony's proprietary Digital Wireless Communication (DWC) technology to transmit audio signals wirelessly between the main unit and up to two remote speakers (sold separately). This allows for flexible placement and configuration options, making it ideal for larger spaces where wired connections may be impractical or unsightly. The ST-S390 supports a variety of audio sources, including CD players, tape decks, radios, and external inputs via RCA or mini-jack connections. It also features a digital clock display and can be controlled using a wireless remote. Overall, the Sony ST-S390 was a well-regarded product in its time for its high-quality audio reproduction, sleek design, and innovative wireless connectivity.
