Marshall VAC-23SHUC
3G-SDI and HDMI to USB-C Converter
-Patrick S.
Description
The Marshall VAC-23SHUC represents a professional-grade signal conversion solution that bridges professional broadcast equipment with computer-based streaming and video conferencing platforms. This versatile converter accepts either HDMI 2.0 or 3G-SDI video inputs, converting them to USB-C output compatible with Mac, PC, and Linux computers for seamless integration with Teams, Zoom, OBS Studio, and other popular streaming applications. The compact, rugged design eliminates the need for external power supplies by drawing power directly from the USB-C connection, reducing cable clutter and simplifying mobile production setups where portability and quick deployment are essential.
Engineered with professional video producers and content creators in mind, the VAC-23SHUC supports video resolutions up to UHD 4K at 30 frames per second via HDMI and USB outputs, while the 3G-SDI input handles formats up to 1080p at 60 frames per second. Active loop-through outputs for both HDMI and SDI inputs enable simultaneous routing to monitoring displays or recording equipment, maintaining the original high-quality signal path while feeding the USB conversion. An input selector switch on the device allows instant switching between HDMI and SDI sources, providing flexibility for multi-camera productions or hybrid workflows mixing consumer and professional video sources.
The VAC-23SHUC's plug-and-play design leverages UVC protocol, presenting itself as a standard camera device to host computers without requiring proprietary drivers or complex configuration. This universal compatibility ensures reliable operation across operating systems and applications, while allowing the host software to control stream parameters including resolution, frame rate, and aspect ratio. A 3.5mm analog stereo audio input automatically embeds into the USB stream, enabling high-quality audio capture from external sources. Whether deployed in houses of worship, educational institutions, corporate training environments, or live event production, the VAC-23SHUC delivers the reliability and performance that professional video applications demand.
Frequently Asked Questions
Can I use both HDMI and SDI inputs simultaneously?
No, the VAC-23SHUC processes one video input at a time, selected via a physical switch on the device. The switch toggles between HDMI and SDI inputs, routing the selected source to the USB-C output. However, both input types feature active loop-through outputs that remain active regardless of which input is selected for conversion. This means you can have both HDMI and SDI sources connected simultaneously, with each routed to its respective loop-through for monitoring or recording, while manually switching which source feeds your computer via USB.
What is the maximum cable length for USB-C connection?
USB-C connections using USB 3.0 protocol are typically reliable up to 3 meters (approximately 10 feet) for video transmission applications. For installations requiring greater distance between the VAC-23SHUC and the host computer, consider using an active USB 3.0 extension cable or a USB-over-IP extender system. Marshall includes a USB-C cable with the VAC-23SHUC, but for permanent installations, high-quality certified USB 3.0 cables ensure consistent performance. Keep in mind that the converter draws power from the USB connection, so cable quality impacts both signal integrity and power delivery.
Does the converter support HDCP content protection?
The VAC-23SHUC's HDCP handling depends on the source content and application. HDCP-protected content from Blu-ray players, streaming devices, or set-top boxes typically cannot be captured or streamed due to copyright protection mechanisms. However, content from video cameras, professional switchers, and computer graphics outputs generally does not employ HDCP protection and converts without issues. For video conferencing and live streaming applications using cameras and presentation sources, HDCP is rarely a concern. If you encounter HDCP-related issues, the problem typically lies with the source device enforcing content protection rather than the converter itself.
Is this compatible with iPads or Android tablets?
The VAC-23SHUC is primarily designed for use with Mac, PC, and Linux computers with full USB 3.0 or USB-C ports. While some modern iPads and Android tablets with USB-C ports support UVC devices, compatibility is not guaranteed and depends on the specific tablet model, operating system version, and application being used. For reliable tablet-based production workflows, verify UVC compatibility with your specific device before deployment, or consider Marshall's dedicated solutions designed explicitly for mobile device integration. Desktop and laptop computers provide the most reliable and well-supported platform for this converter.
