After careful design and engineering, the Model DVS-4A emerges as a high-quality and durable 4x1 DVI switch, perfect for users seeking a user-friendly solution to manage multiple DVI-equipped devices. This compact switch seamlessly routes audio and video signals from four different sources to a single DVI display, such as a plasma or LCD screen, ensuring a clutter-free setup.

Crafted for versatility, the DVS-4A supports single-link, DVI-D video signals with crisp resolutions up to 1920x1200, as well as high-definition television (HDTV) standards up to 1080p, delivering reliable performance for both professional and home entertainment environments. The integrated audio switching capability further enhances the multimedia experience, allowing for smooth transitions between audio sources without the need for additional equipment.

The rear panel of the DVS-4A is thoughtfully arranged with all audio/video and control connections, promoting an organized and accessible interface. The front panel boasts a straightforward push-button switch complemented by clear LED indicators for effortless source selection. Users can enjoy the convenience of multiple control options, including manual operation via the front panel, automatic switching based on video signal detection, or remote operation through the RS-232 serial port, catering to a variety of user preferences.

To accommodate advanced user requirements, the DVS-4A can be configured to operate in three distinct modes: Auto, Scan, and Manual. This feature ensures that the switch can adapt to different scenarios, from automatic source selection to systematic scanning or direct manual control. Additionally, the unit is equipped with EEPROM, which reliably stores the last operating mode even when the power is turned off, ensuring a seamless experience upon restart.

The DVS-4A's long cable equalization feature is particularly noteworthy, as it maintains signal integrity over extended cable runs, making it an ideal choice for setups that require longer distance connections without compromising video quality.
