The Roland V-1SDI is a flexible and versatile video switcher that makes it easy to connect and switch professional 3G SDI cameras and playback sources along with HDMI sources including cameras, smartphones, computers, tablets, and Blu-ray players. Compact and portable, the V-1SDI delivers professional switching results with its easy-to-use hardware interface complete with T-Fader and easy-to-see backlit buttons. With support for 3G-SDI, the V-1SDI can operate at full 1080p resolution and can take advantage of the longer cable distance of SDI, making this compact solution suitable for events and applications in even large spaces with the most professional level of SDI camera sources. The V-1SDI features three dedicated 3G SDI inputs, a third channel input that supports 3G SDI or HDMI, and a fourth channel HDMI input that includes scaling. This makes the V-1SDI ideal in a variety of configurations for both all-camera applications and applications that mix cameras, video sources, and computer data sources. The switcher also includes a quad input multi-viewer with source labeling and audio metering, composition effects including DSK (Downstream Keyer) and picture-in-picture, and a full 14-channel audio mixer. The V-1SDI can be controlled using the V-1SDI RCS application for Mac and PC and remotely via RS-232 connection, making it a powerful and versatile tool for webcasting, videography, installations, and live events.
