The Roland VRC-01 EXP AeroCaster is a complete, all-in-one mobile live streaming system designed to empower content creators, journalists, and educators to produce and broadcast professional-quality multi-camera video from virtually any location. At its core is a compact hardware unit that integrates a video switcher, audio mixer, multi-view monitor, and a 4G LTE cellular modem, eliminating dependency on fixed internet connections. This system is engineered for true portability and rapid deployment, allowing users to connect up to three HDMI video sources—such as cameras, computers, or media players—and instantly stream high-definition content directly to platforms like YouTube, Facebook Live, or a custom RTMP server using built-in cellular data connectivity.

Operation is centered on a responsive 7-inch capacitive touchscreen which serves as both a live multi-viewer, displaying all camera feeds and the program output, and as the primary control surface for switching, adjusting audio levels, and managing stream settings. The system includes essential production tools like picture-in-picture effects, a title keyer for lower-thirds, and a color correction tool to match different cameras. For audio, it features two combo XLR/TRS inputs with phantom power for professional microphones, along with a built-in speaker for monitoring. The entire system is powered by a removable, hot-swappable battery pack, ensuring continuous operation during remote broadcasts.

Housed in a rugged, portable case with integrated mounting points for cameras and accessories, the AeroCaster is built for the demands of field production. It represents a paradigm shift in live streaming technology by combining professional video mixing, reliable cellular bonding for robust internet connectivity, and long-lasting battery power into a single, cohesive package. This system enables users to bypass traditional infrastructure limitations and deliver stable, high-quality live video directly from the field with unprecedented ease and flexibility.
