Powerful 4K Switching and Streaming in a Portable, All-in-One Design

Roland’s popular V-1 series has led the industry since 2004, redefining entry-level video switching with innovative, professional-grade products that are easy for anyone to operate with minimal training. The V-1-4K sets a new benchmark, offering comprehensive support for today’s 4K 60p workflows in a compact, accessible, and user-friendly hub for live events, houses of worship, conference rooms, livestreaming, and more.

HDMI Connectivity with Input Scaling

The V-1-4K features five HDMI inputs with scalers on every channel, enabling seamless switching between HD and 4K 60p HDR video sources. Five HDMI output channels include multi-viewer functionality, allowing independent video signals to be fed to a main monitor, a confidence monitor, and other destinations without a distribution amplifier.

Flexible Routing

The five video inputs and six total outputs (HDMI plus USB streaming) offer flexibility for a wide range of production needs. In addition to program, preview, and multi-view outputs, output channels 3 and 4 can be assigned to any output bus and any input signal via 4K-to-HD downscalers.

Video Composition Tools

The V-1-4K makes it simple to keep audiences engaged with layered graphics and visual effects. Three composition layers allow you to use scalable picture-in-picture images and add titles, logos, social media comments, and more.

Efficient Multi-Angle Shots with ROI

The ROI (Region of Interest) processor lets you compose up to four shots from a single 4K camera image, such as a wide shot of the stage, a medium shot of a speaking panel, and close-ups of each speaker. This powerful feature elevates your production value without increasing camera count, complexity, or costs. Using the V-1-4K RCS or
V-1-4K Remote app, it’s easy to set and adjust cropped areas from a computer or iPad.

Professional Graphics in 4K

Graphics Presenter software for Windows allows you to create stunning titles and graphics without the need for expensive third-party graphic presentation solutions. V-1-4K setup is quick and straightforward, requiring only a single HDMI connection to send fill and key signals from the computer to the switcher.

Graphics Presenter Version 3.0 and later supports 4K and HD workflows with a wide selection of ready-to-edit templates, including animated title text, sports scores, motion graphics, and more. The software and templates are available free of charge, and additional content is periodically provided for download on Roland Cloud.

Plug-and-Play Streaming Up to 4K 60p

The V-1-4K uses the same connection technology as webcams for a plug-and-play streaming experience. Simply connect the USB-C output to a computer and start streaming with Zoom, Microsoft Teams, or any streaming platform that supports a standard webcam connection.

Deep PTZ Camera Integration

Robotic PTZ (pan-tilt-zoom) cameras greatly expand your production capabilities, thanks to their small size and remote-controlled positioning. The V-1-4K includes built-in control support for select Canon, JVC, Panasonic, Sony, PTZOptics, Avonic, and VISCA-compatible PTZ LAN cameras. Mix and match different brands and operate up to five PTZ cameras simultaneously. The V-1-4K Remote app for iPad is an ideal companion for PTZ operation, providing remote camera controls from the tablet.

High-Quality Audio Mixing and Effects

The V-1-4K features 14 channels of audio mixing and a wide selection of processing tools, including equalizers and compressors. There are also sync delays on all input and output busses to align audio with video if needed. I/O routing options include main, monitor, and two aux buses supporting complex audio configurations for hybrid events.

Customizable Control Pads

Eight user-assignable pads provide instant control of many functions during live events. The pads are organized into four banks, providing direct access to 32 operations, including video input routing, audio muting, system configuration access, and more. It’s also possible to control functions in the Graphics Presenter software when the host computer is connected via USB.

Versatile Tools for Remote Operation

The V-1-4K supports extended workflows with dedicated software apps and a variety of remote devices.

The free V-1-4K Remote app for iPad supports wireless LAN connectivity to operate functions via a portable touch interface.
VenuSet is a free customizable control panel app that allows you to configure essential controls, buttons, and faders to fit venue needs and operator skill levels.
Use the free V-1-4K Remote Control Software to operate the switcher from a large display on a Mac or Windows computer.
Seamlessly integrate with system installations via the LAN connector.
Set up a tally light with Roland’s Smart Tally.

V-1-4K Remote Control for iPad

The V-1-4K Remote app turns an iPad into an efficient touch interface for the V-1-4K, with versatile connectivity via a USB or LAN (Wi-Fi) connection. Run essential switching functions, mix audio with virtual faders, change settings and effect parameters quickly, and create custom scenes for fast, efficient setup changes.

V-1-4K RCS for macOS and Windows

The V-1-4K RCS application for macOS and Windows goes even further than the iPad app, providing extended hardware control from your computer via USB, wired LAN, or wireless LAN (Wi-Fi) connections. The V-1-4K RCS can run at the same time as your streaming software over USB, and you can manage all video and audio switching from your large computer screen, including some operations that are unavailable from the V-1-4K panel.

VenuSet Customizable Control Panel App

The VenuSet app (iPadOS/Mac/Windows) offers a friendly, customizable solution that makes it easier for anyone to operate the V-1-4K and other Roland video products. With this configurable app, system integrators can build unique panels with essential functions for different applications, enabling fluid remote control of video switching, audio levels, memories, Graphics Presenter software, and more.
