The Wohler PRESTO is a compact, robust switcher designed to facilitate rapid selection and monitoring of up to 16 standard-definition SDI (Serial Digital Interface) video sources. Housed in a durable half-rack 1U enclosure, it is an efficient tool for control rooms, flypacks, or production trucks where space is limited but professional connectivity is required. The unit features an intuitive front-panel interface, often with a large push-button selector and a clear display, allowing operators to quickly monitor various sources. It manages not only the video signal but also the embedded audio signals within the SDI stream. The PRESTO is built for the reliability demanded by broadcast environments, ensuring clean switching and signal integrity.
